Mastering the Fundamentals: A Guide to Gilbert Strang’s Linear Algebra Lecture Notes

Gilbert Strang 's lecture notes and associated course material are widely praised for their intuitive, application-heavy approach rather than abstract mathematical rigor. While he is often called the "GOAT" (Greatest of All Time) by students, reviews indicate that your experience will depend on whether you prefer "learning by doing" or formal proofs.
