Use the modified latex plugin to properly display math:

$\begin{equation} y = ax + b \end{equation}$

or you can try something more complex:

$\begin{eqnarray*} \Psi_0 &=& -C_{abcd} Y_0^a m^b Y_1^c m^d e^{-2i\gamma} \\ \Psi_4 &=& -C_{abcd} Y_1^a \bar{m}^b Y_1^c \bar{m}^d e^{2i\gamma} \end{eqnarray*}$

You can type inlined mathematics like $y_1=\sqrt(ax^2+bx+c)$ as you would in latex.
