Query: Good Topic Range- Obtuse Explanations

I found this book thoroughly frustrating.I assumed that a book with "for Game Developers" would make concepts easier to understand for the less mathematically inclined in this world. Quite the oppposite, I found my Calculus textbook explained vectors much easier.He spends very little time actually explaining the concepts instead opts to throw formulas at the reader. Understandably, formulas are necessary to be mathematically concise, but he could at least spend time discussing them. Now I could forgive him his obtuse explanations if I had a set of practice problems to work with, but there are none. I wasn't even aware of the calculation errors until I read the other reviews, so this only lowers my esteem for the author.Now to be fair, I haven't gotten to many of the later topics, so it's possible the book will get better. The few I have looked at, however, do not lend me to such optimism. Purchase at your own risk.
