I have to label the equations in one of my answer but I can't find way to do so.

How does one number equations and tables while writing an answer on a Stack Exchange site?

(I just want to use it on Physics.SE but I am guessing probably it is possible on every site.)

This question came from our site for professional and enthusiast programmers.

An example would have been much appreciated. – hjpotter92 Nov 24 '13 at 13:02
Any Stack Exchange site does not have a single answer as MathJax is only enabled on specific sites that require it (Physics, Math, etc). It is not enabled on Stack Overflow however. – psubsee2003 Nov 24 '13 at 13:21
@hjpotter92 say I have some equation which I needed to refer to in order to explain things correctly. In latex one simply uses \label and \ref to refer to equation (or anything in general), but with mathjax (on physics.SE) it does not work. I can you use \tag but again I can not refer I have to manually write the number. Although it is not so important but I think I would still like to know if there is a way to simply copy latex code and have it working with not much trouble. – The Imp Nov 24 '13 at 22:47

After checking editing-help page on Physics site, I noticed that it also uses MathJAX for equations etc. similar to what Mathematics has. You can go through a quick reference guide for MathJAX available on Meta Mathematics.

To directly answer your question, you can use \tag{}.
