Software hosting and version control platform GitHub now supports LaTeX formatted math within Markdown. For more information, see LaTeX/Mathematics in Wikibooks.

Support for displaying math expressions has been a highly requested feature. Now users can utilise the $ and $$ delimiters natively to insert math expressions in TeX and LaTeX style syntax.

GitHub’s math rendering capability uses MathJax; an open-source, JavaScript-based display engine. MathJax supports a wide range of LaTeX macros and several useful accessibility extensions.

How to add math expressions?

Users can add mathematical expressions in two ways:

  1. Inline expressions 

This sentence uses `$` delimiters to show math inline

Math expression: 3x-1 + (1+x)2

Code:  $\sqrt{3x-1}+(1+x)^2$

  1. Block expressions 

To add a math expression as a block, start a new line and delimit the expression with two dollar symbols $$.

Math expression:

Code:  $$\left( \sum_{k=1}^n a_k b_k \right)^2 \leq \left( \sum_{k=1}^n a_k^2 \right) \left( \sum_{k=1}^n b_k^2 \right)$$

GitHub’s move has sparked a flurry of comments on social media. 

But not all are impressed.  “I have seen this feature in gitlab since a very long time ago. It’s always good to see progress, but it seems that github is years behind gitlab,” said Jordi Garra Tico, a Senior security engineer at METACO.

Meanwhile, Emad Elsaid, a software engineer at Twitter, said:

“Why is the syntax $$ instead of regular code blocks like “`mathml for example? the chosen format extends markdown syntax with a special syntax that won’t render properly in other markdown editors.”
