[[MediaWiki]] [[Browser engine|renders]] mathematical equations using a combination of [[HTML]] and a variant of [[LaTeX]].

The version of LaTeX used is a subset of [[AMS-LaTeX]] markup, a superset of [[LaTeX]] markup which is in turn a superset of [[TeX]] markup, for [[Mathematical notation|mathematical formulas]]. Only a limited part of the full TeX language is supported; see below for details.{{efn|Although, in all cases mentioned, TeX is generated by [[compiler|compilation]], and not by an interpreter program, there is one essential difference between, e.g., [[Donald Knuth|Knuth]]'s [[TeX]] or [[Leslie Lamport|Lamport]]'s [[LaTeX]] and the present implementation: whereas in the first two cases the compiler typically generates an ''all-in-one'' printable output, which has the quality of a whole book with all chapters, sections and subsections, and where no line is "special", in the present case one has, typically, a mixture of TeX images (more precisely: PNG images) for the equations, embedded into usual text, and with short TeX elements usually replaced by HTML parts. As a consequence, in many cases TeX-elements, e.g. vector symbols, "stick out" below (or above) the text line. This "sticking out" is ''not''&nbsp; the case in the above-mentioned original products, and the HTML-substitutes for small TeX additions to the text are often insufficient in quality for many readers. In spite of these shortcomings, the present product characterized by "many embedded PNG-images" should be preferred for small texts, where the equations do not dominate.}}

By default SVG images with non-visible [[MathML]] are generated. The older [[Portable Network Graphics|PNG]] images can be set via [[Help:Preferences|user preferences]].{{efn|This can cause difficulty with setting the baseline as vertical alignment with the surrounding text can also be a problem (see [[bugzilla:32694|bug 32694]])}} On some browsers like [[Firefox]], it is possible to use MathML for display via [https://addons.mozilla.org/firefox/addon/native-mathml extensions]; see the main extension page at [[Mw:Extension:Math|mw:Extension:Math]] for details. Client side [[MathJax]] is no longer supported.

==Basics==

Math markup goes inside {{tag|math}}. Chemistry markup goes inside <code><nowiki><math chem>...</math></nowiki></code> or {{tag|chem}}. All these tags use TeX.

The TeX code has to be put literally: MediaWiki templates, predefined templates, and parameters cannot be used within math tags: pairs of double braces are ignored and "#" gives an error message. However, math tags work in the then and else part of #if, etc. See {{tim|Demo of attempt to use parameters within TeX}} for more information.

The now deprecated tag <code><nowiki><ce></nowiki></code> was considered too ambiguous, and it has been replaced by <code><nowiki><chem></nowiki></code>.<ref>{{cite web |title=Consider a longer, less ambiguous name for <ce> |date=December 18, 2016 |author=Ed Sanders |publisher=[[Wikimedia Foundation]] |url=https://phabricator.wikimedia.org/T153606 |accessdate=April 24, 2017}}</ref> 

===LaTeX commands===

LaTeX commands are case-sensitive, and take one of the following two formats:

*They start with a backslash \ and then have a name consisting of letters only. Command names are terminated by a space, a number or any other "non-letter".
*They consist of a backslash \ and exactly one non-letter.

Some commands need an [[argument]], which has to be given between curly braces { } after the command name. Some commands support optional [[parameter]]s, which are added after the command name in square brackets []. The general syntax is:

 \commandname[option1,option2,...]{argument1}{argument2}...

===Special characters===

The following symbols are reserved characters that either have a special meaning under LaTeX or are unavailable in all the fonts. If you enter them directly in your text, they will normally not render, but rather do things you did not intend.

 # $ % ^ & _ { } ~ \

These characters can be entered by prefixing the escape character backslash <code>\</code> or using special sequences:

 \# \$ \% ^\wedge \& \_ \{ \} \sim \backslash

yielding
:<math> \# \$ \% ^\wedge \& \_ \{ \} \sim \backslash</math>.

The backslash character \ can ''not'' be entered by adding another backslash in front of it (\\); this sequence is used for line breaking. For introducing a backslash in math mode, you can use <code>\backslash</code> instead which gives <math>\backslash</math>.

The command <code>\tilde</code> produces a tilde which is placed over the next letter. For example, <code>\tilde{a}</code> gives <math>\tilde{a}</math>. To produce just a tilde character ~, use <code>\tilde{}</code> which gives <math>\tilde{}</math>, placing a ~ over an empty box. Alternatively <code>\sim</code> produces <math>\sim</math>, a large centred ~ which may be more appropriate in some situations.

The command <code>\hat</code> produces a hat over the next character, for example <code>\hat{o}</code> produces <math>\hat{o}</math>. For a stretchable version use <code>\widehat{abc}</code> giving <math>\widehat{abc}</math>. The wedge <code>\wedge</code> is normally used as a mathematical operator <math>\wedge</math> the sequence <code>^\wedge</code> produces <math>^\wedge</math> the best equivalent to the ASCII caret ^ character.

===Spaces===

"Whitespace" characters, such as blank or tab, are treated uniformly as "space" by LaTeX. Several consecutive [[whitespace character]]s are treated as one "space". See [[#Spacing|below]] for commands that produces spaces of different size.

===LaTeX environments===

''Environments'' in LaTeX have a role that is quite similar to commands, but they usually have effect on a wider part of formula. Their syntax is:
<syntaxhighlight lang="latex">
 \begin{environmentname}
   text to be influenced
 \end{environmentname}
</syntaxhighlight>
Environments supported by Wikipedia include ''matrix'', ''align'', etc. See [[#Fractions, matrices, multilines|below]].

===Rendering===
The font sizes and types are independent of browser settings or CSS. Font sizes and types will often deviate from what HTML renders. Vertical alignment with the surrounding text can also be a problem; a work-around is described in the [[Help:Displaying_a_formula#Alignment with normal text flow|"Alignment with normal text flow"]] section below. The [[Help:User style#CSS selectors|CSS selector]] of the images is <syntaxhighlight lang="latex" inline>img.tex</syntaxhighlight>.

{{outdated|topic=Alt-Text}}

The [[WP:ALT|alt text]] of the PNG images, which is displayed to visually impaired and other readers who cannot see the images, and is also used when the text is selected and copied, defaults to the wikitext that produced the image, excluding the <code><nowiki><math></nowiki></code> and <code><nowiki></math></nowiki></code>. You can override this by explicitly specifying an <syntaxhighlight lang="latex" inline>alt</syntaxhighlight> attribute for the <syntaxhighlight lang="latex" inline>math</syntaxhighlight> element. For example, <syntaxhighlight lang="latex" inline><math alt="Square root of pi">\sqrt{\pi}</math></syntaxhighlight> generates an image <math alt="square root of pi">\sqrt{\pi}</math> whose alt text is "Square root of pi". This should not be confused with the ''title'' attribute that produces popup text when the hovering over the PNG image, for example <syntaxhighlight lang="latex" inline><math title="pi">\pi</math></syntaxhighlight> generates an image <math title="pi">\pi</math> whose popup text is "pi".

Apart from function and operator names, as is customary in mathematics, variables and letters are in italics; digits are not. For other text, (like variable labels) to avoid being rendered in italics like variables, use <syntaxhighlight lang="latex" inline>\text</syntaxhighlight> or <syntaxhighlight lang="latex" inline>\mathrm</syntaxhighlight> (formerly <syntaxhighlight lang="latex" inline>\rm</syntaxhighlight>). You can also define new function names using <syntaxhighlight lang="latex" inline>\operatorname{...}</syntaxhighlight>. For example, <syntaxhighlight lang="latex" inline>\text{abc}</syntaxhighlight> gives <math>\text{abc}</math>. <syntaxhighlight lang="latex" inline>\operatorname{...}</syntaxhighlight> provides spacing before and after the operator name when appropriate, as when <syntaxhighlight lang="latex" inline>a\operatorname{sn}b</syntaxhighlight> is rendered as <math>a\operatorname{sn}b</math> (with space to the left and right of "sn") and <syntaxhighlight lang="latex" inline>a\operatorname{sn}(b+c)</syntaxhighlight> as <math>a\operatorname{sn}(b+c)</math> (with space to the left and not to the right). LaTeX's starred version, <syntaxhighlight lang="latex" inline>\operatorname*</syntaxhighlight> is not supported, but a workaround is to add <syntaxhighlight lang="latex" inline>\limits</syntaxhighlight> instead. For example, <syntaxhighlight lang="latex" inline>\operatorname{sn}_{b>c}(b+c) \qquad \operatorname{sn}\limits_{b>c}(b+c)</syntaxhighlight> renders as
:<math>\operatorname{sn}_{b>c}(b+c) \qquad \operatorname{sn}\limits_{b>c}(b+c)</math>.

Latex does not have full support for Unicode characters, and not all characters render. Most Latin characters with accents render correctly. However some do not, in particular those that include multiple diacritics (e.g. with Latin letters used in Vietnamese) or that cannot be precomposed into a single character (such as the uppercase Latin letter W with ring), or that use other diacritics (like the ogonek or the double grave accent, used in Central European languages like Polish, or the horn attached above some vowels in Vietnamese), or other modified letter forms (used in IPA notations, or African languages, or in medieval texts), some digram ligatures (like Ĳ in Dutch), or Latin letters borrowed from Greek, or small capitals, as well as superscripts and subscript letters. For example, <syntaxhighlight lang="latex" inline>\text{ð}</syntaxhighlight> and <syntaxhighlight lang="latex" inline>\text{þ}</syntaxhighlight> (used in Icelandic) will give errors.

The normal way of entering quotation marks in text mode (two back ticks for the left and two apostrophes for the right), such as <syntaxhighlight lang="latex" inline>\text{a ``quoted'' word}</syntaxhighlight> will not work correctly. As a workaround, you can use the Unicode left and right quotation mark characters, which are available from the "Symbols" dropdown panel beneath the editor: <syntaxhighlight lang="latex" inline>\text{a “quoted” word}</syntaxhighlight>.

====Force-rerendering of formulas====
MediaWiki stores rendered formulas in a [[web cache|cache]] so that the images of those formulas do not need to be created each time the page is opened by a user. To force the rerendering of all formulas of a page, you must open it with the getter variables <code>action=purge&mathpurge=true</code>. Imagine for example there is a wrong rendered formula in the article [[Integral]]. To force the re-rendering of this formula you need to open the URL https://en.wikipedia.org/w/index.php?title=Integral&action=purge&mathpurge=true . Afterwards you need to [[WP:Bypass your cache|bypass your browser cache]] so that the new created images of the formulas are actually downloaded. See also [[mw:Extension:Math#Purging pages that contain equations]] for more details.

==TeX vs HTML==
{{See also|Wikipedia:Rendering math}}
TeX markup is not the only way to produce special characters. As this comparison table shows, sometimes similar results can be achieved in HTML using [[Template:Math]]. See also [[Help:Special characters]].

| <syntaxhighlight lang="html5" inline>{{math|{{abs|''z'' + 1}} &le; 2}}</syntaxhighlight>
| {{math|{{abs|''z'' + 1}} &le; 2}}
|}

Care should be taken when writing sets within {{tlx|math}}, as braces can conflict with template syntax.  The {{tlx|mset}} template is available to help with this as shown in the example above.  Likewise, {{tlx|abs}} encloses its parameter inside vertical bars to help with the pipe character conflicting with template syntax.

The codes on the left produce the symbols on the right, but the latter can also be put directly in the wikitext, except for ‘=’.

The project has not reached a consensus on HTML and TeX because each has advantages in some situations.

===Native MathML===

The default MathML/SVG [[Browser engine|renderer]] option, selectable through [[Special:Preferences#mw-prefsection-rendering|My Preferences - Appearance - Math]], generates hidden MathML code. This code can be used by screen readers and other assistive technology. To actually display the [[MathML]] in Firefox you can install the [https://addons.mozilla.org/en-US/firefox/addon/native-mathml/ Native MathML] extension, or simply copy [https://github.com/fred-wang/webextension-native-mathml/blob/master/content-scripts/mediawiki.css its CSS rules] to your Wikipedia [[Help:User style|user stylesheet]]. In either case, you must have [https://developer.mozilla.org/en-US/docs/Mozilla/MathML_Project/Fonts fonts that support MathML] installed on your system. For copy-paste support also install [https://addons.mozilla.org/en-US/firefox/addon/mathml-copy/ MathML Copy]. Details on using MathML in other systems can be found at [[Mw:Extension:Math|mw:Extension:Math]].

===Display attribute===
The {{tag|math|o}} tag can take a <code>display</code> attribute with possible values of <code>inline</code> and <code>block</code>.

====Inline====

If the value of the display attribute is inline, the contents will be rendered in inline mode; i.e., there will be no new paragraph for the equation and the operators will be rendered to consume only a small amount of vertical space.

=====Example=====
The sum <math display="inline">\sum_{i=0}^\infty 2^{-i}</math> converges to 2.

The next line-width is not disturbed by large operators.

The code for the math example reads:
:<syntaxhighlight lang="xml" inline><math display="inline">\sum_{i=0}^\infty 2^{-i}</math></syntaxhighlight>

=====Technical implementation=====
Technically the command ''\textstyle'' will be added to the user input before the tex command is passed to the renderer. The result will be displayed without further formatting by outputting the image or MathMLelement to the page.

====Block====
In block-style the equation is rendered in its own paragraph and the operators are rendered consuming less horizontal space.

=====Example=====
The equation <math display="block">\text{geometric series:}\quad \begin{align} \sum_{i=0}^\infty 2^{-i}=2 \end{align}</math>

It was entered as
:<syntaxhighlight lang="xml" inline><math display="block">\text{geometric series:}\quad \sum_{i=0}^\infty 2^{-i}=2 </math></syntaxhighlight>

=====Technical implementation=====
Technically the command ''\displaystyle'' will be added to the user input, if the user input does not contain the string ''\displaystyle'' or ''\align'' before the tex command is passed to the renderer. The result will be displayed in a new paragraph.
Therefore, the style of the MathImage is altered i.e. the style attribute "display:block;margin:auto" is added.
For MathML it is ensured that display=inline is replaced by display block which produces a new paragraph

====Not specified====

If nothing is specified the current behavior is preserved. That means all equations are rendered in display style but not using a new paragraph.

=====Example=====

The sum <math>\sum_{i=0}^\infty 2^{-i}</math> converges to 2.

The next line-width is disturbed by large operators.

The code for the math example reads:
:<syntaxhighlight lang="tex" inline><math>\sum_{i=0}^\infty 2^{-i}</math></syntaxhighlight>

The equation
:<math>\text{geometric series:}\quad \sum_{i=0}^\infty 2^{-i}=2 </math>

It was entered as
:<syntaxhighlight lang="tex" inline><math>\text{geometric series:}\quad \sum_{i=0}^\infty 2^{-i}=2 </math></syntaxhighlight>

====Equation numbering====

The templates {{tl|NumBlk}} and {{tl|EquationRef}} can be used to number equations. The template {{tl|EquationNote}} can be used to refer to a numbered equation from surrounding text. For example, the following syntax:

: <syntaxhighlight lang="text" inline>{{NumBlk|:|<math>x^2 + y^2 + z^2 = 1</math>|{{EquationRef|1}}}}</syntaxhighlight>

produces the following result (note the equation number in the right margin):

{{NumBlk|:|<math>x^2 + y^2 + z^2 = 1</math>|{{EquationRef|1}}}}

Later on, the text can refer to this equation by its number using syntax like this:

: <syntaxhighlight lang="text" inline>As seen in equation ({{EquationNote|1}}), blah blah blah...</syntaxhighlight>

The result looks like this:

: As seen in equation ({{EquationNote|1}}), blah blah blah...

The equation number produced by {{tl|EquationNote}} is a link that the user can click to go immediately to the cited equation.

===Alphabets and typefaces===
{{See also|Wikipedia:LaTeX symbols#Fonts}}
[[Texvc]] cannot render arbitrary [[Unicode]] characters. Those it can handle can be entered by the expressions below. For others, such as [[Cyrillic]], they can be entered as Unicode or HTML entities in running text, but cannot be used in displayed formulas.

===Color===
Equations can use color with the <code>\color</code> command. For example,
*<syntaxhighlight lang="latex" inline>{\color{Blue}x^2}+{\color{Orange}2x}-{\color{LimeGreen}1}</syntaxhighlight>
*: <math>{\color{Blue}x^2}+{\color{Orange}2x}-{\color{LimeGreen}1}</math>
*<syntaxhighlight lang="latex" inline>x_{1,2}=\frac{{\color{Blue}-b}\pm\sqrt{\color{Red}b^2-4ac}}{\color{Green}2a }</syntaxhighlight>
*: <math>x_{1,2}=\frac{{\color{Blue}-b}\pm\sqrt{\color{Red}b^2-4ac}}{\color{Green}2a}</math>
There are several alternate notations styles
*<syntaxhighlight lang="latex" inline>{\color{Blue}x^2}+{\color{Orange}2x}-{\color{LimeGreen}1}</syntaxhighlight> works with both texvc and MathJax
*: <math>{\color{Blue}x^2}+{\color{Orange}2x}-{\color{LimeGreen}1}</math>
*<syntaxhighlight lang="latex" inline>\color{Blue}x^2\color{Black}+\color{Orange}2x\color{Black}-\color{LimeGreen}1</syntaxhighlight> works with both texvc and MathJax
*: <math>\color{Blue}x^2\color{Black}+\color{Orange}2x\color{Black}-\color{LimeGreen}1</math>
*<syntaxhighlight lang="latex" inline>\color{Blue}{x^2}+\color{Orange}{2x}-\color{LimeGreen}{1}</syntaxhighlight> only works with MathJax
*: <math>\color{Blue}{x^2}+\color{Orange}{2x}-\color{LimeGreen}{1}</math>

Some color names are predeclared according to the following table, you can use them directly for the rendering of formulas (or for declaring the intended color of the page background).

Color should not be used as the ''only'' way to identify something, because it will become meaningless on black-and-white media or for color-blind people. See [[WP:Manual of Style (accessibility)#Color]].

Latex does not have a command for setting the background color. The most effective way of setting a background color is by setting a CSS styling rule for a table cell:
<pre style="display: inline-block;">
{| class="wikitable" align="center"
| style="background-color: gray;"      | <math>x^2</math>
| style="background-color: Goldenrod;" | <math>y^3</math>
|}
</pre>

Rendered as:
{| class="wikitable" align="center"
| style="background-color: gray;"      | <math>x^2</math>
| style="background-color: Goldenrod;" | <math>y^3</math>
|}

Custom colours can be defined using:
<syntaxhighlight lang="latex">\definecolor{myorange}{rgb}{1,0.65,0.4}\color{myorange}e^{i \pi}\color{Black} + 1 = 0</syntaxhighlight>

:<math>\definecolor{myorange}{rgb}{1,0.65,0.4}\color{myorange}e^{i \pi}\color{Black} + 1 = 0</math>

===Formatting issues===

====Spacing====
{{See also|Quad (typography)}}

TeX handles most spacing automatically, but you may sometimes want manual control.

{| class="wikitable"
! Feature !! Syntax !! How it looks rendered
|-
| double quad space || <syntaxhighlight lang="latex" inline>a \qquad b</syntaxhighlight> || <math>a \qquad b</math>
|-
| quad space || <syntaxhighlight lang="latex" inline>a \quad b</syntaxhighlight> || <math>a \quad b</math>
|-
| text space || <syntaxhighlight lang="latex" inline>a\ b</syntaxhighlight> || <math>a\ b</math>
|-
| text space in text mode || <syntaxhighlight lang="latex" inline>a \text{ } b</syntaxhighlight> || <math>a \text{ } b</math>
|-
| large space || <syntaxhighlight lang="latex" inline>a\;b</syntaxhighlight> || <math>a\;b</math>
|-
| medium space || <syntaxhighlight lang="latex" inline>a\<b</syntaxhighlight> || [not supported]
|-
| small space || <syntaxhighlight lang="latex" inline>a\,b</syntaxhighlight> || <math>a\,b</math>
|-
| tiny space (use for multiplication of factors) || <syntaxhighlight lang="latex" inline>ab</syntaxhighlight> || <math>ab</math>
|-
| tiny space (syntax space ignored) || <syntaxhighlight lang="latex" inline>a b</syntaxhighlight> || <math>a b</math>
|-
| no space (use for multi-letter variables) || <syntaxhighlight lang="latex" inline>\mathit{ab}</syntaxhighlight> || <math>\mathit{ab}</math>
|-
| small negative space || <syntaxhighlight lang="latex" inline>a\!b</syntaxhighlight> || <math>a\!b</math>
|}

Automatic spacing may be broken in very long expressions (because they produce an overfull hbox in TeX):

: <syntaxhighlight lang="latex" inline>0+1+2+3+4+5+6+7+8+9+10+11+12+13+14+15+16+17+18+19+20+\cdots</syntaxhighlight>
: <math>0+1+2+3+4+5+6+7+8+9+10+11+12+13+14+15+16+17+18+19+20+\cdots</math>

This can be remedied by putting a pair of braces { } around the whole expression:

: <syntaxhighlight lang="latex" inline>{0+1+2+3+4+5+6+7+8+9+10+11+12+13+14+15+16+17+18+19+20+\cdots}</syntaxhighlight>
: <math>{0+1+2+3+4+5+6+7+8+9+10+11+12+13+14+15+16+17+18+19+20+\cdots}</math>


When relational symbols such as <math>\uparrow</math> are employed as ordinary symbols, for example in [[bra–ket notation]], additional spacing may have to be avoided:
{| class="wikitable"
|-
! Feature
! Syntax
! How it looks rendered
|-
| without special formatting
| <syntaxhighlight lang="latex" inline>| \uparrow \rangle</syntaxhighlight>
| <math>| \uparrow \rangle</math>
|-
| explicit opening and closing delimiter
| <syntaxhighlight lang="latex" inline>\left| \uparrow \right\rangle</syntaxhighlight>
| <math>\left| \uparrow \right\rangle</math>
|-
| with additional braces
| <syntaxhighlight lang="latex" inline>| {\uparrow} \rangle</syntaxhighlight>
| <math>| {\uparrow} \rangle</math>
|-
| arrow as ordinary symbol
| <syntaxhighlight lang="latex" inline>| \mathord\uparrow \rangle</syntaxhighlight>
| <math>| \mathord\uparrow \rangle</math>
|}

====Alignment with normal text flow====

Because of the default CSS

<syntaxhighlight lang="CSS">img.tex { vertical-align: middle; }</syntaxhighlight>

an inline expression like <math>\int_{-N}^{N} e^x\, dx</math> should look good.

If you need to align it otherwise, use <code><nowiki><math style="vertical-align:-100%;">...</math></nowiki></code> and play with the <syntaxhighlight lang="latex" inline>vertical-align</syntaxhighlight> argument until you get it right; however, how it looks may depend on the browser and the browser settings.

If you rely on this workaround, if and when the rendering on the server gets fixed in a future release, this extra manual offset will suddenly make every affected formula align ''incorrectly''. So use it sparingly, if at all.

===Unimplemented elements and workarounds===

====<syntaxhighlight lang="latex" inline>\oiint</syntaxhighlight> and <syntaxhighlight lang="latex" inline>\oiiint</syntaxhighlight>====

Elements which are not yet implemented are <syntaxhighlight lang="latex" inline>\oiint</syntaxhighlight>, namely a two-fold integral <syntaxhighlight lang="latex" inline>\iint</syntaxhighlight> {{nowrap|(<math>\iint</math>)}} with a circular curve through the centre of the two integrals, and similarly <syntaxhighlight lang="latex" inline>\oiiint</syntaxhighlight>, a circular curve through three integrals. In contrast, <syntaxhighlight lang="latex" inline>\oint</syntaxhighlight> {{nowrap|(<math>\oint</math>)}} exists for the single dimension (integration over a curved line within a plane or any space with higher dimension).

These elements appear in many contexts: <syntaxhighlight lang="latex" inline>\oiint</syntaxhighlight> denotes a [[surface integral]] over the closed 2d boundary of a 3d region (which occurs in much of 3d [[vector calculus]] and physical applications – like [[Maxwell's equations]]), likewise <syntaxhighlight lang="latex" inline>\oiiint</syntaxhighlight> denotes integration over the closed 3d boundary (surface volume) of a 4d region, and they would be strong candidates for the next TeX version. As such there are a lot of workarounds in the present version.

:{| class="toccolours collapsible collapsed" width="80%" style="text-align:left"
!<syntaxhighlight lang="latex" inline>\oiint</syntaxhighlight> and <syntaxhighlight lang="latex" inline>\oiiint</syntaxhighlight> using currently implemented symbols
|-
| <syntaxhighlight lang="latex" inline>\oiint</syntaxhighlight> looks like:

*<math>\iint\limits_{S}\!\!\!\!\!\!\!\!\!\!\!\subset\!\supset \mathbf D \cdot \mathrm{d}\mathbf A</math>, which uses <syntaxhighlight lang="latex" inline>\iint</syntaxhighlight> along with <syntaxhighlight lang="latex" inline>\subset</syntaxhighlight> and <syntaxhighlight lang="latex" inline>\supset</syntaxhighlight> (overdrawn after backspacing):
: <syntaxhighlight lang="latex" inline>\iint\limits_{S}\!\!\!\!\!\!\!\!\!\!\!\subset\!\supset \mathbf D \cdot \mathrm{d}\mathbf A</syntaxhighlight>
*<math>\int\!\!\!\!\int_{\partial V}\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\;\;\;\bigcirc\,\,\mathbf D\cdot\mathrm{d}\mathbf A</math>, which uses <syntaxhighlight lang="latex" inline>\int</syntaxhighlight> twice (with some backward [[kern (typography)|kerning]]) along with <syntaxhighlight lang="latex" inline>\bigcirc</syntaxhighlight> (also overdrawn after backpacing) to produce a more consistent circle:
: <syntaxhighlight lang="latex" inline>\int\!\!\!\!\int_{\partial V}\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\;\;\;\bigcirc\,\,\mathbf D\cdot\mathrm{d}\mathbf A</syntaxhighlight>

<syntaxhighlight lang="latex" inline>\oiiint</syntaxhighlight> (should also be preferably more tightly kerned) looks more or less like:

*<math>\int\!\!\!\!\!\int\!\!\!\!\!\int_{\partial V}\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\;\;\;\subset\!\supset \mathbf D\cdot\mathrm{d}\mathbf A</math> which uses three \int symbols (with more backward kerning) with \subset and \supset (overdrawn after backspacing):
: <syntaxhighlight lang="latex" inline>\int\!\!\!\!\!\int\!\!\!\!\!\int_{\partial V}\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\;\;\;\subset\!\supset \mathbf D\;\cdot\mathrm{d}\mathbf A</syntaxhighlight>
*<math>\int\!\!\!\!\!\int\!\!\!\!\!\int_{\partial V}\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\;\;\;\bigcirc\,\,\mathbf D\;\cdot\mathrm{d}\mathbf A</math>, which uses three <syntaxhighlight lang="latex" inline>\int</syntaxhighlight> symbols (with more backward kerning) along with <syntaxhighlight lang="latex" inline>\bigcirc</syntaxhighlight> (also overdrawn after backspacing):
: <syntaxhighlight lang="latex" inline>\int\!\!\!\!\!\int\!\!\!\!\!\int_{\partial V}\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\;\;\;\bigcirc\,\,\mathbf D\;\cdot\mathrm{d}\mathbf A</syntaxhighlight>
|}

However, since no standardisation exists as yet, any workaround like this (which uses many <syntaxhighlight lang="latex" inline>\!</syntaxhighlight> symbols for backspacing) should be avoided, if possible. See below for a possibility using PNG image enforcement.

Note that <syntaxhighlight lang="latex" inline>\iint</syntaxhighlight> (the double integral) and <syntaxhighlight lang="latex" inline>\iiint</syntaxhighlight> (the triple integral) are still not kerned as they should preferably be, and are currently rendered as if they were successive <syntaxhighlight lang="latex" inline>\int</syntaxhighlight> symbols; this is not a major problem for reading the formulas, even if the integral symbols before the last one do not have bounds, so it's best to avoid backspacing "hacks" as they may be inconsistent with a possible future better implementation of integrals symbols (with more precisely computed kerning positions).

=====<syntaxhighlight lang="latex" inline>\oiint</syntaxhighlight> and <syntaxhighlight lang="latex" inline>\oiiint</syntaxhighlight> as PNG images=====

These symbols are available as PNG images which are also integrated into two templates, {{tl|oiint}} and {{tl|oiiint}}, which take care of the formatting around the symbols.

The templates have three parameters:

;preintegral: the text or formula immediately before the integral
;intsubscpt: the subscript below the integral
;integrand: the text or formula immediately after the integral

======Examples======

*[[Stokes' theorem]]: <syntaxhighlight lang="tex" inline><math>\oiint_{\scriptstyle S}( \nabla \times \mathbf{F} ) \cdot {\mathrm d}\mathbf{S} = \oint_{\partial S} \mathbf{F} \cdot {\mathrm d}\boldsymbol{\ell} </math></syntaxhighlight>

: <math>\oiint_{\scriptstyle S}( \nabla \times \mathbf{F} ) \cdot {\mathrm d}\mathbf{S} = \oint_{\partial S} \mathbf{F} \cdot {\mathrm d}\boldsymbol{\ell} </math>

*[[Ampère's circuital law|Ampère's law]] + correction: <syntaxhighlight lang="tex" inline>{{oiint

| preintegral=<math>\oint_C \mathbf{B} \cdot {\mathrm d} \boldsymbol{\ell} = \mu_0 </math>
| intsubscpt = <math>{\scriptstyle S}</math>
| integrand = <math>\left ( \mathbf{J} + \epsilon_0\frac{\partial \mathbf{E}}{\partial t} \right ) \cdot {\mathrm d}\mathbf{S}</math>
}}</syntaxhighlight>

: {{oiint
| preintegral=<math>\oint_{\partial S} \mathbf{B} \cdot {\mathrm d} \boldsymbol{\ell} = \mu_0 </math>
| intsubscpt = <math>{\scriptstyle S}</math>
| integrand = <math>\left ( \mathbf{J} + \epsilon_0\frac{\partial \mathbf{E}}{\partial t} \right ) \cdot {\mathrm d}\mathbf{S}</math>
}}

*Continuity of [[4-momentum]] flux (in [[general relativity]]):<ref>{{Cite book|title=Gravitation|author1=J. A. Wheeler |author2=C. Misner |author3=K. S. Thorne | year=1973|publisher=W. H. Freeman & Co|edition=2nd|isbn=0-7167-0344-0}}</ref><syntaxhighlight lang="tex" inline> <math display=block>
\mathbf{P} = \oiiint_{\scriptstyle \partial \Omega} \mathbf{T} \cdot {\mathrm d}^3\boldsymbol{\Sigma}

</math></syntaxhighlight>
<math display=block>
\mathbf{P} = \oiiint_{\scriptstyle \partial \Omega} \mathbf{T} \cdot {\mathrm d}^3\boldsymbol{\Sigma}
         = 0
</math>

=====Oriented <syntaxhighlight lang="latex" inline>\oiint</syntaxhighlight> and <syntaxhighlight lang="latex" inline>\oiiint</syntaxhighlight> as PNG images=====

Some variants of <syntaxhighlight lang="latex" inline>\oiint</syntaxhighlight> and <syntaxhighlight lang="latex" inline>\oiiint</syntaxhighlight> have arrows on them to indicate the sense of integration, such as a line integral around a closed curve in the clockwise sense, and higher dimensional analogues. These are not implemented in [[TeX]] on Wikipedia either, although the template {{tl|intorient}} is available - see link for details.

====Arc notation <syntaxhighlight lang="latex" inline>\overarc</syntaxhighlight>====

<syntaxhighlight lang="latex" inline>\overarc</syntaxhighlight> is not yet implemented to display the arc notation. However, there exists a workaround: use <syntaxhighlight lang="latex" inline>\overset{\frown}{AB}</syntaxhighlight>, which gives
<math>\overset{\frown}{AB}</math>

====Triple dot <syntaxhighlight lang="latex" inline>\dddot</syntaxhighlight>====
<syntaxhighlight lang="latex" inline>\dddot</syntaxhighlight> is not implemented. For a workaround use <syntaxhighlight lang="latex" inline>\overset{...}{x}</syntaxhighlight>, which gives
<math>\overset{...}{x}</math>.

====Starred operatorname <syntaxhighlight lang="latex" inline>\operatorname*</syntaxhighlight>====
The starred version of <code>\operatorname</code> is not currently supported. A workaround for
<syntaxhighlight lang="latex">\operatorname*{median}_{j\,\ne\,i} X_{i,j}</syntaxhighlight> 
is
<syntaxhighlight lang="latex">\operatorname{\underset{\mathit{j\,\ne\,i}}{median}} X_{i,j}</syntaxhighlight>

====Strikethrough====
Strikethrough like <syntaxhighlight lang="latex" inline>\sout</syntaxhighlight> or <syntaxhighlight lang="latex" inline>\st</syntaxhighlight> is not implemented, nor is overlapping like <syntaxhighlight lang="latex" inline>\rlap</syntaxhighlight>.  This means struck characters like ƛ are difficult to type, except the hardcoded <syntaxhighlight lang="latex" inline>\hbar</syntaxhighlight>.  A workaround suffix for a normal strikethrough is <syntaxhighlight lang="latex" inline>q \!\!\!\frac{}{\ }</syntaxhighlight>, and for elevated strikethrough is <syntaxhighlight lang="latex" inline>\lambda \!\!\!^{{}^\underline{\ \ }}</syntaxhighlight>, which give

:<math>q\!\!\!\frac{}{\ }, \quad \lambda\!\!\!^{{}^\underline{\ \ }}</math>

===Syntax to avoid===

The texvc processor accepts some non-standard syntax. These should be avoided as the MathJax based renderers do not support these syntax.

====Unicode characters====

Non-ASCII Unicode characters like {{pi}} work in MathML, and MathJax but not in texvc so should currently be avoided. In the long term it may be possible to use these characters.

====Deprecated syntax====

The following texvc commands are now deprecated and should be avoided. This is part of an effort to update the math engine 
see [[ mw:Extension:Math/Roadmap]] for details. A bot [[User:Texvc2LaTeXBot]] will replace this syntax on the English Wikipedia.

==Chemistry==
<!-- this is linked from [[Template:Xtag]] -->{{shortcut|WP:MATHCHEM}}
There are three ways to render chemical sum formulas as used in [[chemical equation]]s:
*{{xtag|chem|p}} ({{xtag|ce|p}} is a deprecated alias for it)
*{{xtag|math|p|params=chem}}
*{{tlx|chem}} and {{tlx|chem2}}

{{xtag|chem|p|content=X}} is short for <syntaxhighlight lang="xml" inline><math chem>\ce{X}</math></syntaxhighlight>
(where <code>X</code> is a chemical sum formula)

Technically, {{xtag|math|params=chem}} is a <code>math</code> tag with the extension <code>mhchem</code> enabled, according to the [http://docs.mathjax.org/en/latest/input/tex/extensions/mhchem.html MathJax documentation].

Note, that the commands <code>\cee</code> and <code>\cf</code> are disabled, because they are marked as deprecated in the [http://www.ctan.org/pkg/mhchem mhchem LaTeX package documentation].

If the formula reaches a certain "complexity", spaces might be ignored (<code><nowiki><chem>A + B</chem></nowiki></code> might be rendered as if it were <code><nowiki><chem>A+B</chem></nowiki></code> with a positive charge). In that case, write <code><nowiki><chem>A{} + B</chem></nowiki></code> (and ''not'' <code><nowiki><chem>{A} + {B}</chem></nowiki></code> as was previously suggested). This will allow auto-cleaning of formulas once the bug will be fixed and/or a newer <code>mhchem</code> version will be used.

Please note that there are still [https://phabricator.wikimedia.org/T140217 major issues] with mhchem support in MediaWiki. Some issue can be solved by enabling the extension using {{xtag|math|params=chem}} and formatting individual items with <code>\ce</code>. For example, {{markup2|m=<syntaxhighlight lang="tex" inline><math chem>\ce{pIC_{50}} = -\log_{10} \ce{(IC_{50})}</math></syntaxhighlight>|r=<math chem>\ce{pIC_{50}} = -\log_{10} \ce{(IC_{50})}</math>}}

==Commutative diagrams==
[[File:First isomorphism theorem (plain).svg|thumb|A sample commutative diagram, created in the manner described]]
To make a [[commutative diagram]], there are three steps:

# write the diagram in [[TeX]]
# [[#Convert to SVG|convert to SVG]]
# [[commons:Commons:First steps/Upload form|upload the file]] to [[commons:|Wikimedia Commons]]

===Diagrams in TeX===

[http://www.tug.org/applications/Xy-pic/ Xy-pic]{{efn|Use the barr option for commutative diagrams, e.g., <code>\usepackage[cmtip,all,barr]{xy}</code>.}} ([http://tex.loria.fr/graph-pack/doc-xypic/xyguide-html/xyguide-html.html online manual]) is the most powerful and general-purpose diagram package in [[TeX]]. Diagrams created using it can be found at [[commons:Category:Xy-pic diagrams|Commons: Category:Xy-pic diagrams]].

Simpler packages include:

*[[American Mathematical Society|AMS's]] [http://www.dante.de/CTAN//help/Catalogue/entries/amscd.html amscd]
*Paul Taylor's [http://www.ctan.org/tex-archive/macros/generic/diagrams/taylor/ diagrams]
*François Borceux [http://www.ctan.org/tex-archive/help/Catalogue/entries/borceux.html Diagrams]

The following is a template for Xy-pic:
<syntaxhighlight lang=latex>
\documentclass[border=10pt]{standalone} % Crop to size, remove page numbers, leave margin
\usepackage[all]{xy} % Loading the XY-Pic package
\begin{document}
\SelectTips{eu}{} % Euler (shorter) arrowheads (tips)
$$
\xymatrix{
%%% Diagram goes here %%%
}
$$
\end{document}
</syntaxhighlight>

Using postscript drivers may in some cases give smoother curves and will handle fonts differently:
<syntaxhighlight lang=latex>\usepackage[all, ps, dvips]{xy}</syntaxhighlight>

===Convert to SVG===

Once you have produced your diagram in LaTeX (or TeX), you can convert it to an SVG file using the following sequence of commands:

<syntaxhighlight lang=bash>
pdflatex file.tex
pdf2svg file.pdf file.svg
</syntaxhighlight>

The [http://pdfcrop.sourceforge.net pdfcrop] and [http://www.cityinthesky.co.uk/opensource/pdf2svg pdf2svg] utilities are needed for this procedure. You can alternatively use [http://www.pdftron.com/pdf2svg/ pdf2svg] from PDFTron for the last step.

If you do not have [[pdfTeX]] (which is unlikely) you can use the following commands to replace the first step (TeX → PDF):
<syntaxhighlight lang=bash>
latex file.tex
dvipdfm file.dvi
</syntaxhighlight>

In general, you will not be able to get anywhere with diagrams without TeX and Ghostscript, and the <syntaxhighlight lang="latex" inline>inkscape</syntaxhighlight> program is a useful tool for creating or modifying your diagrams by hand. There is also a utility <syntaxhighlight lang="latex" inline>pstoedit</syntaxhighlight> which supports direct conversion from Postscript files to many vector graphics formats, but it requires a non-free plugin to convert to SVG, and regardless of the format, [[User:Ryan Reich|this editor]] has not been successful in using it to convert diagrams with diagonal arrows from TeX-created files.

These programs are:

*a working TeX distribution, such as [[TeX Live]]
*[[Ghostscript]]
*[[pstoedit]]
*[[Inkscape]]

===Upload the file===
{{See also|commons:Commons:First steps/Upload form}}
{{See also|Help:Contents/Images and media}}

As the diagram is your own work, upload it to [[commons:|Wikimedia Commons]], so that all projects (notably, all languages) can use it without having to copy it to their language's Wiki. (If you've previously uploaded a file to somewhere other than Commons, to Commons.)

; Check size: Before uploading, check that the default size of the image is neither too large nor too small by opening in an [[SVG#Support in applications|SVG application]] and viewing at default size (100% scaling), otherwise adjust the <code>-y</code> option to <code>dvips</code>.
; Name: Make sure the file has a [[WP:Naming conventions|meaningful name]].
; Upload: [[commons:Special:Userlogin|Login to Wikimedia Commons]], then <span class="plainlinks">[http://commons.wikimedia.org/w/index.php?title=Special:Upload&uselang=ownwork upload the file]</span>; for the '''Summary''', give a brief description.

Now go to the [[Help:Image page|image page]] and add a [[commons:Commons:First steps/Quality and description#Good file descriptions|description]], including the '''source code''', using this template:

<pre>
{{Information
 |description =
     {{en|1= '''Description [[:en:Link to WP page|topic]]'''}}
 |source = {{own}}, created as per:
  [[:en:Help:Displaying a formula#Commutative diagrams]];
  source code below.
 |date = '''The Creation Date, like 1999-12-31'''
 |author = '''[[User:YourUserName|Your Real Name]]'''
 |permission = {{self|PD-self '''(or [[commons:Licensing#Well-known licenses|other license]])'''
     |author = '''[[User:YourUserName|Your Real Name]]'''}}
}}

==TeX source==

<syntaxhighlight lang="latex">
 % TeX source here
</syntaxhighlight>
 
[[Category:Commutative diagrams]]
[[Category:Xy-pic diagrams]]
[[Category:Images with LaTeX source code]]
</pre>

; Source code
:*Include the source code in the [[Help:Image page|image page]], in the {{mono|Source}} section of the <code><nowiki>{{</nowiki>[[commons:Template:Information|Information]]}}</code> template, so that the diagram can be edited in future.
:*Include the complete <code>.tex</code> file, not just the fragment, so future editors do not need to reconstruct a compilable file.
:*You may optionally make the source code section collapsible, using the <code><nowiki>{{</nowiki>[[commons:Template:cot|cot]]}}</code>/<code><nowiki>{{</nowiki>[[commons:Template:cob|cob]]}}</code> templates.
:*(Don't include it in the Summary section, which is just supposed to be a summary.)
; License
: The most common license for commutative diagrams is <code>[[commons:Template:PD-self|PD-self]]</code>; some use <code>[[commons:Template:PD-self|PD-ineligible]]</code>, especially for simple diagrams, or other licenses. Please ''do not'' use the [http://www.gnu.org/copyleft/fdl.html GFDL], as it requires the entire text of the GFDL to be attached to any document that uses the diagram.
; Description
: If possible, link to a Wikipedia page relevant to the diagram. (The <code>1=</code> is necessary if you use nest templates within the description, and harmless otherwise.)
; Category
: Include <code><nowiki>[[Category:Commutative diagrams]]</nowiki></code>, so that it appears in [[commons:Category:Commutative diagrams]]. There are also subcategories, which you may choose to use.
; Include image
: Now include the image on the original page via <code><nowiki>[[File:Diagram.svg]]</nowiki></code>

===Examples===

A sample conforming diagram is [[commons:File:PSU-PU.svg]].

== Semantics and links ==
While links from formulas using LaTeX macros such as ''\href'' or ''\url'' or are currently not supported, one can link individual math expressions to wikidata items to explain the meaning of individual terms of mathematical expressions. For example,
{{markupv
|r=<math qid=Q35875>E=mc^2</math>
|m=<syntaxhighlight lang="latex" inline><math qid=Q35875>E=mc^2</math></syntaxhighlight>
}}
links to [https://en.wikipedia.org/wiki/Special:MathWikibase?qid=Q35875 a special page that displays additional information on that formulas]<!--(feature availible from 10th of Janurary 2020)-->.
To change the information shown on the specialpage navigate to the wikidata item linked at the bottom of the special page. Use the ''has part'' property to link parts of the equation to other wikidata items with their respective Wikipedia Articles. This is not limited to individual identifiers, but can also be used to link more complex terms.  

A condensed version of that specialpage, might be shown in the future as popup [[phab:T239357]].
