I have just the book for you: the essentials of high school math for adults: http://www.lulu.com/shop/ivan-savov/no-bullshit-guide-to-mat...

If you like this one, you can followup with the MATH&PHYS book which covers mechanics (PHYS101) and calculus. And if you like that one, you can follow up with the liner algebra book.

All along the way, I recommend you try solving exercises and problems using pen and paper. Ideally you can also create custom "test questions" for yourself using SymPy https://minireference.com/static/tutorials/sympy_tutorial.pd... 1. start with a simple math question or equation related to what you're studying right now, 2. solve it by hand, 3. compare your answer with the answer obtained by SymPy.

Good luck on your journey. Math is very deep so don't be in a rush. Enjoy the views along the way!
