📕 Proof-Based Math Readings is a free, independent online reading group where we study the mathematics required for economics master’s and PhD programs through an intuitive approach. Active since May 2023.

My Notes On Mathematical thinking fundamentals Course By Dr. Keith Devlin for developers and problem-solvers. Master logical reasoning, proof techniques, and mathematical language that transforms how you approach coding, algorithms, and complex problem-solving.

Solutions, notes, and worked derivations from Concrete Mathematics by Graham, Knuth, and Patashnik. The goal is to build a rigorous, well-argued set of proofs and computations while developing deeper intuition for discrete math, number theory, and combinatorial analysis.
