It took me time to really appreciate and realize how special this book is. The author wants one thing: That is you to understand Linear Algebra. This makes him different from many other books where the mindset is that "the reader will figure it out anyway" or "when you don't understand it maybe it's not your thing". The author doesn't care about such things and this book is for everyone. I don't come from a mathematics background and worked through page 300 together with completing every excercise. Math can be easy when it's explained so.
