This book is freaking amazing! I was using it as material for my linear algebra course. Found it after all of material from my college just wasn't clear enough for me and I have to say that this book beats every online material or book regarding this subject I have taken a look at. Every proof is thoroughly explained, a great number of different problems is provided and overall the book is written in such manner that even someone that isn't fully into mathematics could understand it. I cannot recommend the book enough.
