Title: 2x2 Determinants Exercise

Hi, this is my first attempt at a new exercise, and it's on finding 2x2 Determinants. I've been trying to follow Sal's video guide to this module, and I've mostly finished it, although I can't figure out how to colour the individual numbers inside the matrix itself, it doesn't seem to let me do it within the LaTeX tags. Does anyone have any idea how to do this?

Also, I'm new to github as well, so if there is anything I should have done a certain way (with branches, etc) but didn't, then just let me know and I'll try to fix it.

Any feedback would be greatly appreciated.
