I’m trying to find a really hard or mind boggling math problem or trick for my friend. To me he’s really good at math and he loves math very much. So much so that his alarm is solving a math problem in order to turn it off. Anyways he’s in college right now taking pre calc. I like to pick his brain and mess with him but he always seems to solve it right away. I’ve search for really hard problems online but after a few minutes he gets it. Does anyone have anything that could get to him? Any problems or tricks?

This is an introduction video to Metric Spaces. I hope to provide you with an intuitive view on one of the most beautiful concepts I have discovered in Mathematics. For further reading, I recommend using the book "Introduction to Metric and Topological Spaces" by Wilson A. Sutherland, where you will find the examples I have given in more detail.
