My name is Kody Amour, and I teach free undergraduate mathematics courses on YouTube. I'm currently developing three YouTube courses simultaneously: Discrete Math, Linear Algebra, Real Analysis, Topology, Number Theory and Complex Analysis. These courses correspond to playlists that I am constructing indefinitely.

You have already given me a view and your watch time, which means a lot to me already. Your participation in this community contributes to exponential growth of this channel. If you'd like to give even more than you already have, please like, subscribe, share on a math SubReddit, comment, ring the bell, etc...

**Please only give if you have the financial ability to do so**
