About MathBuff
MathBuff is built and curated by university professors. We carefully design the problems and topics to help people of all levels learn and appreciate mathematics.
Our content is low-cost, engaging, and spans introductory through graduate-level mathematics. We specialize in designing short, focused courses that build toward a single important result or theorem, each one carrying exactly the ideas you need to understand it.
Every course is paired with spaced-repetition practice, so old ideas stay fresh while you learn new ones.
