I started this channel when I was teaching college math from the basics of pre-Algebra all the way through the Calculus series. I would like to make more videos. Message me if you have a video you would like an answer too.

I also help parents who want to know why they have to learn this "new math". I can explain the reasoning behind the a topic being introduced.

I have been working in the ML world for the last 4 years, and would be happy to research a topic and make a video about it. If you need help digging into something let me know and I might just be able to help you.
