This is how I currently am relearning upper high school math. It’s tremendously helpful as I am a why guy.

Why is the angle called m? Why is a combination nPr * (1/r)? What is 1/r doing there?

I use mathacademy.com as my source of practice. Usually that’s enough but I tend to fall over if small details aren’t explained and I can’t figure out why those details are there.

In high school this was punished. With state of the art LLMs, I have a good tutor.

Also it’s satisfying to just upload a page in my own handwriting and it understands what I did, and is able to correct me there.
