Can we include math symbols?

In my answer to this question I suddenly felt the need to include formula's. I am sorry for this, it is a bad habit of mine, but I am sure it will happen more often.

Is there any way to format those formula's nicely in a way that I have seen for example on the math.stackexchange site?

• Lots of aviation concepts use formulas, so please do turn it on! – Lnafziger Dec 19 '13 at 21:20
• Now that you're in public beta - if you have interest in seeing this enabled, adding an answer here to show cases where it would have been extremely helfpul to have MathJax enabled would be the best way to start. – Tim Post Dec 30 '13 at 15:35
• This question appears to be off-topic because the answer is obsolete (this was asked during private beta). There was also another question asked later: meta.aviation.stackexchange.com/questions/145/… – Qantas 94 Heavy Jan 8 '14 at 4:53

$$e=mc^2$$
