I'm studying for the ACT and I can't figure out how to do this problem. I feel like it should be easy, but I really need an explanation.
(I can't make a less-than-or-equal-to sign on my keyboard, so when you see a * that's what it means.)
When -3 * x * 4 and -1 * y * 2, what is the least possible value for x - y?
I know that the answer is F. but I need an explanation why.
