How to input equations into posts?

[Cornraker]

I'm not sure if ii'm asking this question on the right forum but how do i put a neat equation into here to ask a question instead, for example, 4+x^3/2. How do i put that into a neat equaiton like you would find in a textbook? Thanks.

Hi Cornraker! Welcome to PF! :smile:

Either use the X2 tag just above the Reply box …

4+x3/2

or type before and after … 4+x^{3/2} :wink: …

(and bookmark http://www.physics.udel.edu/~dubois/lshort2e/node61.html#SECTION008100000000000000000 for some more symbols)
