I don't use a lot of advanced mathematics these days -- most of my time seems to be spent shuffling bytes from point A to point B.

I do have two kids in school, though, and my daughter just finished some higher level calculus courses. In my attempts to help her, I've found that we have endless and fantastic resources available online. Every type of problem has a YouTube video explaining, step by step, how to solve them.

In my opinion, there's never been a better time in history to learn advanced (or even basic!) mathematics than right now.
