# How to type math symbols in this forum [duplicate]

How can I type math symbols in this forum, like set operators, etc.?

If this question is repeated, I am sorry I just searched and couldn't find an answer.

And could anyone give me hint to use Tags for this question?

Thank you!

Using Latex and $<\text{the thing you need to type here}>$
E.g. $x^2$ is $\$$x^2\$$$\infty$is$\$$\infty\$$
$e^{i\pi} + 1 = 0$ is $\$$e^{i\pi} + 1 = 0\$$ • If you use backticks (), then anything between them appears as unformatted text: $x^2$`. – Emily May 7 '14 at 2:43 First, once you get$5$reputation, you can ask this on http://meta.stackexchange.com Never mind that, it will only get closed as a duplicate of the MathJax tutorial I will talk about below. Next, if you want a LaTeX / MathJax tutorial, click here. If you are looking for specific symbols like$\pi\$ (pi), then you should try Dextify.
