Michael Penn has 353 000 YouTube subscribers and 1 330 400 views across the 91 videos we track, counted Sep 8, 2026.
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 understa
