Mgccl's Ivory Towerso tired

The book can greatly improve problem solving skill. Too bad the soltions are not clear enough. 500 questions should take me around 2 months.

This is the only book about linear algebra form my library, I'm still reading it, so I can not give a exact rating right now. From what I have see, it is not the exact book I would want to use for learning linear algebra. The book forcous on the mechinical side of mathematics, like how to do operations between matrices. The book have a little help with enrich the idea of the matrix. For example, the book never talked about the geometric meaning of a determinant. After one reading the book, he might become masters at finding determinants and solve system of linear equations, but what's the point, even a TI-83 calculator can do it.
Get this book only if you want to learn how to manipulate matrix instead of understanding it. This book can be used as a nice outline of the course.

The book present some proofs covering many fields of mathematics, include modular arithmetics, prime numbers, graph theory and set theory. The book is easy to understand, great book for teenagers who interests in math but doesn't have the ability to read the complicated research papers.

The math textbook for my precalculus class. Good read, 4th edition.

Not the best textbook out there, but I don't read enough textbook to know how good this one is.

Math is NICE!
Almost everything about summation are in this book. Also binary coefficient, discrete probability.
