I don't know. I've always just liked figuring out variables and such. Plus, I had really good teachers for Algebra 1 and 2. It's easy to love a class when you're good at it and the teachers take the time to make sure you understand the core concepts. Also, math answers don't change! Once you understand how to figure things out, you'll know how to do it every time. Unlike with some other classes where the concepts/accepted outcomes change every few months it seems.
