reStructuredText does not support math

I have tried every approach for embedding equations into my rst markup on Github, but none seem to work:

```
.. math::

\beta = \alpha + \epsilon^2
```

and

```
.. raw:: latex html

\[ \beta = \alpha + \epsilon^2 \]
```

as well as adding a MathJax script to the rst file.

Since I largely develop statistical software, its important to be able to add math to my wiki pages and docs. Is this something that will be added in the near future, or is there a workaround?
