LaTeX for Messenger

With the help of the TeX coding language, you can typeset math. That is, you can write equations and other kinds of mathematical formulas with the standard formatting and fonts used in academic and technical publications (e.g., textbooks). But Facebook Messenger has no built-in support for TeX code.

If you know how to code in TeX, and you want to use those skills to talk math with your friends in Facebook Messenger, this extension allows you to do so. While composing a message at facebook.com, write TeX commands between $$ and $$, or [ and ], to display mathematical formulas centered on their own line. Enclose your code in $ ... $ or ( ... ) instead if you want to include a little bit of math in a paragraph. Type $ or \ to include a plain dollar sign or backslash in your message. Otherwise, the characters $ and </code> are interpreted as code.
