An example

Some example from a text file.

Some yaml

markdown: maruku

Some html

<script type="text/x-mathjax-config">
MathJax.Hub.Config({
      tex2jax: {inlineMath: [['$','$'], ['\\(','\\)']]}
      });
</script>
<script type="text/javascript" src="path-to-mathjax/MathJax.js?config=TeX-AMS-MML_HTMLorMML"></script>

Some TeX

$$\forall x, y : \mathbb{Z}, x > 3 \land y < 2 \Rightarrow x^2 - 2y > 5$$

Inline TeX:
x, y : ℤ, x > 3 ∧ y < 2 ⇒ x2 − 2y > 5
