# Enabling TeX in an answer [duplicate]

I searched but didn't find basic information on enabling TeX in an answer. $...$ didn't seem to work.

• @ThomasMcLeod: This should be done in meta, not in the main site. To use LaTeX, just use $...$ or $$...$$ (as well as a handful of other commands such as \begin{align*} and the like). The site should do it automatically. Jan 24, 2011 at 20:44
• @Arturo, sorry, I was in meta but the puter choked and I lost my page. Jan 24, 2011 at 20:49
• @Arturo, tried again to ask a question in meta, but this time got message that I my rep was too low. Jan 24, 2011 at 21:03
• @Thomas McLeod: I've asked that the question be migrated; but in any case, I don't understand what your question is. You simply type LateX and the site should "enable" it. You don't have to do anything other than just type. Jan 24, 2011 at 21:21
• @Arturo, may it's a problem with my browser (IE8). I need to press refresh serveral times before I see the TeX source slowing rendering. Jan 24, 2011 at 21:28
• @ThomasMcLeod: If you are getting [math processing error], then you need to do a cache-clear; shift-refresh does it in Firefox, I don't know how to do it with Internet Explorer. Jan 24, 2011 at 21:33
• @Thomas: In my experience MathJax is unusable in IE8 (as you describe). But it works fine in Chrome or Firefox. Has anyone got MathJax working nicely in IE? Jan 24, 2011 at 21:41
• @Thomas: yes, unfortunately, there is a reputation threshold for asking questions on Meta. The number is quite low, you should be able to surpass it in no time! Jan 24, 2011 at 21:42
