Cut the Crap Linear Algebra (en Inglés) - Nico Biagio Ball

Have you ever read a book and thought, "Goodness gracious, I have no idea what the heck this guy is saying." So have I, and I have decided to counter such an ugly world of incomprehensible math with one that is made to be learned. Books of mathematics are far too concerned with impressing colleagues and hiding their incapabilities behind textbook definitions and assumptions of knowledge. I believe that math is made to teach. So I promise you there will be a definitional or grammatical error in this book, but I also promise you that you will learn more than you ever have in your life. Welcome to the world of Linear Algebra!
