I’ve been experimenting with using countNumberUsage in order to check for correctness and simplificaiton in fractions. Does countNumberUsage check for negative numbers? I’ve been trying to figure out a way to avoid something like a student inputing -3/-1 and it being counted as correct.

It only takes positive numbers, so not sure how to resolve that issue.

I just figured that out. I thought it was something else incorrect in my code.
Guess I’m back to using latex.
