Just starting to use WP. Set up a test blog on wordpress.com. Am interested in math so I pasted in the LaTex example

$latex i\hbar\frac{\partial}{\partial t}\left|\Psi(t)\right>=H\left|\Psi(t)\right>$

directly out of the instructions at http://en.support.wordpress.com/latex/.

However when I posted this to my blog, it just echoed the LaTex code and did not render the formula. What am I doing wrong

The blog I need help with is testing27.wordpress.com.
