Issues Open tasks · Report a bug 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. This extension was part of core MediaWiki until MediaWiki version 1.18. More information about installing and configuring this extension, including for older versions, can be found at Extension:Math/advancedSettings. ## Installation • If using Vagrant, install with vagrant enable-role math && vagrant provision Manual installation • Download and place the file(s) in a directory called Math in your extensions/ folder. • Add the following code at the bottom of your LocalSettings.php: require_once "$IP/extensions/Math/Math.php";
// See below for installation requirements and configuration settings:

• Run the update script which will automatically create the necessary database tables that this extension needs.
• To see math beyond a plain text output, follow instructions below for enabling various math output modes.
•  Done - Navigate to Special:Version on your wiki to verify that the extension is successfully installed.

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 https://phabricator.wikimedia.org

## 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.:

### No rendering

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

### MathJax

Mode: MW_MATH_MATHJAX

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

Setting name Default value Description
$wgMathValidModes array( 'png', 'source', 'mathml' ) Defines the mode allowed on the server.$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.
