This is a hidden gem. At the beginning of many sections, there is a small table or list showing "Problem types: Finding a basis (Problems 5.1–5.30), Testing for linear independence (5.31–5.70)..." This allows you to target your weaknesses ruthlessly. Bad at finding the basis of a null space? Do 20 problems, check your solutions immediately, and watch the fog lift.
Most textbooks give you 20-30 problems at the end of a chapter, with answers to the odds in the back. That’s a teaser. This book shows you the entire reasoning for every single problem. You aren’t just checking a final answer; you are learning the algorithm of thought. For example, when proving that a set of vectors is linearly dependent, the book doesn’t just say "yes" or "no." It walks you through setting up the homogeneous system, performing row reduction, and interpreting the free variables. This is like having a private tutor. 3000 Solved Problems In Linear Algebra By Seymour
Textbooks explain theory. Lectures provide context. But what truly bridges the gap between “I think I understand” and “I can solve any problem” is —massive, relentless, varied practice. This is a hidden gem
If you are struggling in linear algebra, buy this book. If you want to move from a C to an A, buy this book. If you are a tutor or TA looking for a source of practice problems, buy this book. Do 20 problems, check your solutions immediately, and
It won’t teach you the philosophy of vector spaces. But it will teach you how to involving matrices, determinants, eigenvalues, and basis transformations. And in the end, that’s exactly what most of us need.
