Math videos covering a wide variety of topics from theory to application. Calculus, Differential Equations, Number Theory, Proofs, unique problems and much more. I have a second channel that has full course material for higher level math called MathMajor which is geared toward more structured videos that support real classes I teach. My goal is to spread math education, knowledge, and understanding to as many people as possible.
