Prior to v 1.18, Math was supported in core of MediaWiki via the <nowiki><math></nowiki> tag. Now, it's been extracted into the [[mw:Extension:Math|Extension:Math]] extension.
Furthermore, if you want to run a production wiki that uses math formulas, it is recommended that you setup your own '''[[mw:Mathoid]]''' nodejs service which in turn relies on a '''[[mw:RESTBase]]''' service. == Notes about setting it up / History / Status ==# https://phabricator.wikimedia.org/T136812# https://phabricator.wikimedia.org/T154394# https://www.mediawiki.org/wiki/Extension:Math/advancedSettings# https://www.mediawiki.org/wiki/Manual:Math
