I like the 3blue1brown youtube series for explaining mathematical problem solving, like this example explaining a difficult problem from the Putnam: [VIDEO] "And those of you who follow the channel know that rather than just jumping straight to the solution, which in this case will be surprisingly short, when possible I prefer to take the time to walk through how you might stumble upon the solution yourself. That is, make the video more about the problem-solving process than the particular problem used to exemplify it." I bailed out of math around calculus, and these videos helped me at least appreciate what I was missing.

This is an extension of an animation library used by math YouTuber 3blue1brown [0]. He has an excellent channel that I would recommend anything from. One of my favorite videos of his is where he shows the thought process behind solving a level 6 Putnam competition problem and makes it seem almost doable [1]. [0] [LINK] [1] [VIDEO]

3Blue1Brown is really great for learning/refreshing math. He has great visualizations. I especially enjoyed this video (not exactly a math tutorial more of a cool explanation): [VIDEO]
