## LaTeX in WordPress

I just found out that WordPress.com supports LaTeX math markup! It’s pretty easy to use.

$\forall x > 3, p(x) \land p(x+2) \implies\lnot p(x+4)$

(For lack of any ideas original or even remotely profound!)

Now I have to go back and fix all those previous posts… I’ve been pretty lazy about typesetting and usually just used plain letters and computer-style operators (* for multiplication, etc.).  I think I’ve used the `var` tag a couple of times but not consistently.
