I'm kinda new here. May I know how I can insert math here? For example, matrices and the Greek alphabet? Sorry if it's a stupid question, I'm honestly clueless.

Take a look here: MathJax basic tutorial and quick reference
MathJax is how it's all done. If you already know Latex you're $75\%$ of the way there.
