I'm sorry if I posted in a wrong place,

I want to ask if I can use LaTeX synthax in this forum to type maths formulae and symbols

 

Thanks

You can. Enclose it in math tags: [ math]x^2[/ math] -> [math]x^2[/math] (note that there is a bug in the software so the generated text doesn't appear until the page is refreshed)

Thanks

I want to type  x is an element of integers

What do I do?

 

There is an online editor that lets you try things out, and has buttons for common functions: https://www.codecogs.com/latex/eqneditor.php

Try x \in \mathbb{I} [math]x \in \mathbb{I}[/math]

Apart from that, there are various online guides (some linked in that other thread, I think.)

[ math]x^2[/ math]
