I can't figure out how to latexa 3X3 matrix so here's my ghetto method

A =

0 0 -1

0 2 0

0 0 1

What is

2. Relevant equations

I'm trying to find [tex] A^{7} [/tex]

3. The attempt at a solution

I'm assuming there's some type of shortcut to get this... So I did a squared and then multipled a squared times a squared to get a to the fourth... I was about to multiply A times a squared and then that times a to the fourth but I didn't think that was ok to do since multiplication isn't commutative and I don't know which order to multiply... Is my method ok? Any other suggestions?
