Yeah it’s a textbook but I’m going to count it because I’ve literally read every page of it, it’s also the worst textbook I’ve ever read, it doesn’t highlight important facts nor does it indicate vocabulary words. It doesn’t have well maintained sections at all, the only thing I would say was alright about this book is that it demonstrates how to solve example problems well.
Don't waste your time. I have never read an educational textbook that was so unhelpful. I feel like I know even less now than when I started. The author spent so much time going through the math, how adding this number to this number will give you this number. But he never explained where those numbers came from. A quick gloss over what the numbers mean. I hated this book.
