I’m taking discrete math and this is much more helpful than the textbook

What I personally find helpful while this video is explained is to think about uniqueness and existence throughout

Thank you! I’m literally taking an elementary abstract algebra course in a few days and I’ve had a lot of trouble over the years trying to find a simple explanation for what “ well defined” means. This is a breath of relief.

Good video! I would also mention that if the output is not in the co-domain it is not well defined.

Thank you Jake, however I am absolutely cooked this semester to a point far past that of no return. It is certainly over for me, this class is not even required for me I am just stupid.
