I re-learned math via Kahn academy.

While I had a good math education, that was two decades prior. My child was starting to study the Calculus AB curriculum, and I wanted to have some basis for helping them (or at least encouraging them).

I found I literally had to start with adding/ multiplying fractions. I did get through the Calc, but stopped during that section because of time constraints.

But I found the basic math portions of the exercises to be quite helpful and feel like it was a good progression. There are a lot of exercises and it is free.
