I would really love it if there was some type of Leetcode for math. I grew up in a very liberal artsy environment and was actually warned against taking advanced math for most of my life. It wasn't until college, taking requirements for my CS major, that I realized I actually find it fascinating and have an aptitude for it - but then college ended and I just have barely done any math since.

If anyone has any resources on this or general advice I'd love to hear it. It seems to me like all the coolest cutting edge stuff in Tech right now requires a lot of math so I'd love to start grinding at it.
