Multiple Spacing/Math Eq. in School Help

This is a really small suggestion, but can we allow multiple spacing in the school help section?

I was trying to explain how to do augmented matrices and it's really hard to line up the matrices just right with only allowing one space. Sometimes in math and related, it's hard to explain things right or create a picture.

If we can't do that, is it possible to add an equation editor? I know the people over in Physics forum have it. I think its called LaTeX code or something. It would help explain better.
