Introduction to Mathematical Thinking
by [UC Berkeley]
Summary
The Introduction to Mathematical Thinking (IMT) DeCal was a student-led course at UC Berkeley created to help students develop the kind of logical reasoning and mathematical maturity needed for advanced mathematics and computer science. Rather than focusing on calculations, the course teaches students how to read mathematical notation, understand precise definitions, construct rigorous proofs, and recognize sound logical arguments.
Topics include proof techniques, induction, number theory, modular arithmetic, sets, functions, combinatorics, graph theory, probability, and other foundational ideas that form the backbone of higher mathematics. Although the course ended after Spring 2019, all of its lectures, notes, videos, homework, and learning materials remain freely available online, making it a valuable self-study resource for anyone interested in strengthening their mathematical thinking. Whether preparing for university-level mathematics or simply wanting to think more clearly and rigorously, the IMT DeCal provides an accessible and well-structured introduction to the mindset of a mathematician.
