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.


  • Si usas Vagrant , instala con vagrant roles enable math --provision
Instalación manual
  • Descarga y extrae los archivos en el directorio «Math» dentro del directorio extensions/ existente.
  • Añade el siguiente código a tu LocalSettings.php (preferiblemente al final):
    require_once "$IP/extensions/Math/Math.php";
    // See below for installation requirements and configuration settings:
  • Ejecuta el script de actualización, que creará automáticamente las tablas que necesita esta extensión en la base de datos.
  • To see math beyond a plain text output, follow instructions below for enabling various math output modes.
  •   Hecho – Navega a Special:Version en tu wiki para verificar que la apariencia se haya instalado correctamente.


Beginning from MW 1.23+ you can use a Mathoid server that uses MathJax to convert texvc input on the server side to MathML+SVG rendering. Mathoid is the rendering mode that is going to be used on future Wikipedia. For that the following settings are recommended:

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

Check out Mathoid to find instructions how to run your own Mathoid server.

List of all configuration settings

Setting name Default value Description
$wgMathValidModes array( 'png', 'source', 'mathml' ) Defines the mode allowed on the server.
$wgMathMathMLTimeout 20 The timeout for the HTTP-Request sent to the MathML to render an equation, in seconds.
$wgMathDisableTexFilter false Option to disable the tex filter. If set to true any LaTeX expression 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.
$wgMathMathMLUrl http://mathoid.testme.wmflabs.org Defines the link to the mathoid server.

Purging pages that contain equations

Specifying the URL-parameter action=purge does not force the math equation to re-render the math tags. If a complete re-rendering of the math tags is desired the URL-parameter action=purge&mathpurge=true has to be passed. Be aware that this might cause side effects with other pages since the math extension uses the hash of the input TeX-input-string as the caching key. e.g. if you would force the re-rending with mathpurge option for a page containing the equation $E=mc^2$, the new rendering result would be used on all other pages containing $E=mc^2$ after the individual page caches are invalidated.

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.

Further reading

The Math extension can do much more, beside the basics described here. Check out Extension:Math/advancedsettings for old versions and further information.
