hey /sci/, I know there are textbooks on subjects but I found an unknown interest I thought I never had. I love math. Its just mind blowing.
Unfortunately, I smoked alot of weed and was a slacker in high school. I practically forgot everything past Algebra II. Any good tips or book suggestions on getting back in the game? I want to be able to understand and comprehend higher level mathematics, considering I'll be going back to college soon and I know I will need to take calculus classes. Yes I know this isn't going to be an overnight thing. I want to start it as a hobby.

tl;dr trying to learn math from Algebra II and up. Best tips and suggestions.
