Ask HN: Best way to learn math fundamentals?

I'd like to teach myself more math. It has always been a subject I've been interested in, but after calculus and statistics in high school, I stopped learning entirely. I need a refresher on the basics like polynomial algebra, trigonometry, etc, before moving forward. The end goal is to have a solid understand of calculus and linear algebra, for no reason other than the joy of learning something complex and potentially diving into a little ML theory. I've used Khan Academy in the past, but have found that I learn better when I can read what I'm learning. I'm curious what the HN community would recommend. Is there a textbook or set of textbooks that you think are better than others? An collection of online material that you think could help? Any advice is appreciated.

The Art of Problem Solving series of books is relatively affordable to an adult with disposable income and they all come with complete solution manuals: https://artofproblemsolving.com/store/list/aops-curriculum https://artofproblemsolving.com/store/list/aops-curriculum You could spend a year or two doing ~20 problems per day while scheduling review of definitions you've understood and problems you've solved with spaced-repetition software like Anki. Afterwards, you'd be prepared for any undergraduate mathematics curriculum in the world.
