The Math extension provides support for rendering mathematical formulae. An overview of what can currently be done with this extension is found at the English Wikipedia's documentation.

More information about installing and configuring this extension, including for older versions, can be found at Extension:Math/advancedSettingsExtension:Math/advancedSettings.

Viewing math

The Math extension tries to deliver MathML output, with fallback to SVG or PNG images respectively. Depending on the capabilities of the device you are using, the sort of output is chosen. Basic math support works for all browsers. However, for optimal rendering specific tuning may be needed:

Accessibility support is provided by the VoiceOver screen reader but not by Orca yet.


  • VagrantMediaWiki-Vagrant를 사용하고 있는 경우에는, vagrant roles enable math --provision로 설치해주세요

수동 설치

  • 파일을 다운로드해서, extensions/ 폴더 내의 Math 이라는 이름의 디렉터리 내에 설치합니다.
  • 아래의 코드를 LocalSettings.php의 말미에 추가합니다:
    wfLoadExtension( 'Math' );
    // See below for installation requirements and configuration settings:
  • 갱신 스크립트를 실행합니다. 이 스크립트는 이 확장기능을 필요로 하는 데이터 베이스 테이블을 자동적으로 작성합니다.
  • To see math beyond a plain text output, follow instructions below for enabling various math output modes.
  • YesY 완료 - 위키의 ‘Special:Version’에 이동해서, 확장기능이 올바르게 설치된 것을 확인합니다.

To users running MediaWiki 1.24 or earlier:

The instructions above describe the new way of installing this extension using wfLoadExtension() If you need to install this extension on these earlier versions (MediaWiki 1.24 and earlier), instead of wfLoadExtension( 'Math' );, you need to use:

require_once "$IP/extensions/Math/Math.php";

You should additionally go to the page Special:MathStatus to see whether all of the components of the Math extension now work. For any problems you see, the best option is to create a task on

Unfortunately, there is no well tested guide on installing MathoidMathoid and RestbaseRestbase to work with the Math extension, but there is at least a working draft. Extension:Math/RestbaseExtension:Math/Restbase please contribute.

In addition, there is a Guide for Installing and Setting up Mediawiki with Restbase and Mathoid in MW1.28.

Math output modes

The setting $wgMathValidModes holds an array with the names of output modes that can be used for rendering. If multiple modes are enabled, logged-in users can set a personal preference in the appearance pane of their user preferences page.

You can also use the $wgDefaultUserOptions setting to set which of these modes should be the default, e.g.:

$wgDefaultUserOptions['math'] = 'mathml';


Mode: 'mathml' (pre-July 2015: MW_MATH_MATHML)

For MW 1.23 and higher, you can use a Mathoid server that uses MathJax to convert texvc input on the server side to MathML+SVG rendering. This is the most recommended option; Mathoid is the rendering mode that will be used on Wikipedia in the future.

To use Mathoid, the following settings are recommended:

// Set MathML as default rendering option
$wgDefaultUserOptions['math'] = 'mathml';
$wgMathFullRestbaseURL= '';

See Mathoid for instructions on how to run your own Mathoid server. Note that as of March 2017 this is likely to also require a RESTbase server/installation (see task T154394).


Mode: 'png' (pre-July 2015: MW_MATH_PNG)

This is the mode that requires the most setup work, since at least the texvc utility has to be installed for it to work, and ideally texvccheck as well. See Installing texvc for how to install both of these.


Mode: 'latexml' (pre-July 2015: MW_MATH_LATEXML)

Uses the LaTeXML utility. The rendering is done via an online service (set with $wgLaTeXMLUrl, which has a default value).

No rendering

Mode: 'source', (pre-July 2015: MW_MATH_SOURCE)

This mode will forward the Latex input without rendering, presenting it in a <span> element, surrounded by $ :formula $.

Make sure to set $wgMathFullRestbaseURL to 'always' (see below) if you only want the raw latex formula, else an error will appear due to the failed check for PNG depictions.



This mode uses the MathJax application for client-side rendering. It is now deprecated, and requires MediaWiki 1.25 or lower in order to run. See Client-side rendering with MathJax for how to use it.

List of significant configuration settings

설정 이름 기본값 설명
$wgMathValidModes array( 'png', 'source', 'mathml' ) Defines the mode allowed on the server.
$wgMathDisableTexFilterManual:$wgMathDisableTexFilter 'never' Option to disable the tex filter. If set to true any LaTeX espression is parsed this can be a potential security risk. If set to false only a subset of the TeX commands is allowed. See the wikipedia page Help:Math for details. Use "always" to disable this feature.
$wgMathFullRestbaseURL false The math extension gets the default config from the Visual Editor, if available. Details

Tips and tricks

Error reporting

If something is wrong with the math extension you can report that at Phabricator. In addition you should check how your problem relates to the automated unit tests that are generated from the page CoverageTest.
