I've been in the chat "h-bar" physics stackexchange chat, and somebody wrote $\frac{1}{2}$ and it comes up for me like those literal characters and not as $\frac{1}{2}$

Any idea why / how I can enable mathjax in chat?

The guy that posted it said he can see it and thought it might be an issue on my end.

I don't know if it's a bug of some sort, or perhaps i'm just missing an option.

MathJax does not work out-of-the-box on chat; the behaviour you observe is precisely as expected. To turn it on, you need to turn a client-side extension which is described in

but the short of it is that to turn on ChatJax, you can just drag-and-drop the link marked start ChatJax in this page up to your bookmarks bar, and then click the resulting bookmarklet to turn on mathjax in chat.

This is handily linked in the chatroom description, if you ever need it

though indeed it's not the most discoverable text ever written.

  • $\begingroup$ Seriously, though, you should watch it, just for the sheer joy of the visuals. $\endgroup$ Apr 13 '17 at 11:46
