Paul's Online Math Notes
I enjoyed math in high school and some of college, but I could never understand, and it wasn't explained, how to apply it to anything in my life, so I thought of it as basically just fun puzzles and after finishing the required classes I majored in something else.<p>Decades later, I'd like to start learning it again but still want to know how to apply it for practical purposes. Where can I find this kind of approach?
