Can you recommend any books/websites that would help me (re)teach myself math?

I am historically god-awful at mathematics. I still add with my fingers, even.

In high school, I passed geometry only because the teacher was incredibly sympathetic and let me retake test after test; I failed Algebra II and then barely squeaked by when I retook it; then in college, with a liberal arts major, I took “liberal arts math” (finite math) which I failed and had to retake. (I said I was god-awful at math, right?) That is the end of my math experience.

For my own personal development, I would like to be better at math. I want to start at the basics and just reteach myself from there. I have looked into taking a class at a community college, but the registration has already passed so I’m SOL. I have a lot of free time now, so I figured I’d just teach myself.

Thanks in advance.
