# Why doesn't maths render as maths?

On some other SE sites, code in between dollar signs gets rendered as mathematics (using MathJaX, I believe). This doesn't seem to work here? Why not? And how do I get round it?

• This question covers the approach as it is now. If you wish to discuss the availability/utility (or otherwise) of MathJax on the TeX - LaTeX site, please open a separate meta thread. – Joseph Wright Jun 19 '17 at 15:48
