# a post with math

This theme supports rendering beautiful math in inline and display modes using KaTeX engine. You just need to surround your math expression with `$$`

, like `$$ E = mc^2 $$`

. If you leave it inside a paragraph, it will produce an inline expression, just like \(E = mc^2\).

To use display mode, again surround your expression with `$$`

and place it as a separate paragraph. Here is an example:

Note that KaTeX is work in progress, so it does not support the full range of math expressions as, say, MathJax. Yet, it is blazing fast.
