Off the usual course of high school mathematics

[hackedagainanda]

Hey PF! I'm currently studying Algebra and Trigonometry and have been looking at university level math courses. I was hoping there are some to jump into preferably before calculus like crypt analysis, number theory, or combinatorics.Are there "fun" math courses to take that don't rely on calculus?I do plan on learning calculus eventually.

Discrete math (especially combinatorics, graph theory, etc.) can be learned at a basic level before calculus and honestly it was the most fun math course I've ever taken. Sometimes calc is involved, but not always.
