For whatever reason I’ve decided to start relearning all the maths that I’ve forgotten since I was a kid and currently I’m working my way through a Cambridge maths textbook focuses on line equations and all that jazz. I used to be really good at maths mechanics so I guess I want to cover that topic as well. Where I really fell down at school was during pure maths, so hopefully at some point I’d like to cover that as well.

Does anyone have a good online resource that includes lessons, examples and exercises that I could work through?
