Question: Every once in a while I miss having the option to write some LaTeX math on SO. E.g. when [talking about automata](https://stackoverflow.com/questions/885411/how-do-i-build-this-finite-automaton). I'm certainly [not the only one](https://stackoverflow.com/questions/1106929/find-all-combinations-of-coins-when-given-some-dollar-value/1106968#1106968). And I think the person answering [this question](https://stackoverflow.com/questions/1055098/how-do-i-design-the-transition-functions-for-this-pushdown-automaton) would have appreciated it as well. I'm sure there are more examples.

It can be done, look e.g. at the [Physics forums](http://www.physicsforums.com/showthread.php?t=8997). Multiple solutions exits, either by converting the LaTeX code to an image or MathML.

Since the fields of theoretical computer science and computer programming overlap (formal languages, data structures, ...), and because plenty of users are acquainted with LaTeX, I think it makes sense to provide support for mathematical notation on SO. What do you think?

Answer: 
We use mathematical notation all the time in the `algorithm` and `math` questions - LaTeX would be incredibly helpful *(especially if it wouldn't be too much work to implement - mathoverflow.com already has it!)*
We should look into how mathoverflow did it. They have a very neat integrated solution which I think should be added to all the SO-like sites.
