Abstract Algebra 9.1: Normal Subgroups

[@johndavies729]

Thank you so much for all these videos, Patrick! I've been self-teaching abstract algebra for a while now and this playlist has been indispensable! AA is such a cool branch of math - at first it seems pretty mundane - you start with some basic theorems and definitions, you manipulate them a bit and produce some corollaries. But then, all of a sudden you find these glimmers of intrinsic beauty that make mathematics so special!

You're very welcome. It is sad that so much of education considers math to only be a tool, when it can also be an expression of art and beauty. I'm always happy to hear from someone that realizes that.

Studying for finals and I wish I saw your videos earlier. You explain it way better than my professor does who has me confused constantly.
