> If you see typeset mathematics below, then MathJax is working. If you see TeX code instead, MathJax is not working for you.

> \[ \frac{-b\pm\sqrt{b^2-4ac}}{2a} \]

> MathJax is not working!

> If the mathematics does not show up properly, you may not have not installed the MathJax web fonts correctly. Follow the steps in the installation instructions.

> If you obtained MathJax via an archive (`.zip`) file, the fonts are included and should not need any special installation. If you obtained MathJax via svn, the distribution includes a `fonts.zip` file that you will need to unpack before the image fonts will work. Once unpacked, you should have a directory with the following hierarchy:

>         mathjax/
>           ...
>           fonts/
>             HTML-CSS/
>               TeX/
>                 eot/
>                   ...
>                 imagedata.js
>                 png/
>                   ...
>                 otf/
>                   ...
>                 svg/
>                   ...
>           fonts.zip
>           ...
