Ask HN: How to learn math from zero for adults?

Paul's Math Notes https://tutorial.math.lamar.edu/

I neglected math a lot in HS too and tried the Khan Academy route, but figured out over time that you really can find your gaps and fill them on demand by focusing on the work you want to do.

I wouldn’t discourage you from trying a more comprehensive approach to building a great foundation in math. Math is awesome and if you enjoy it, go for it. If you want to stay focused on ML, you might do alright by figuring out what you need as you go. Just walk back from each problem until you find your bearings, then dig in.

Math is huge and you could find it takes forever to arrive at the skills you need to do the specific thing you want to do.

Browsing https://math.stackexchange.com/questions can be a nice way to learn math notation and to see which math topics you find interesting.

(also, occasionally a question or answer will be so good you'll instantly grok the math concept even if you haven't learned it formally before; it's rare but magical when it happens).

I would advise you to download[1] free maths class 10,11,12 books which is taught to indian students. They are well written, covers calculus, lots of exercises to practice as well to test your knowledge.
