If you're here to develop a deeper understanding of math and not just plug in numbers and formulas, this is not the correct book. It doesn't even teach you necessary skills in order to complete problems. It just assumes you know these things. It's very confusing in some sections and you definitely need to expand your horizon with other materials to enrich your understanding. The instructions just aren't that clear. This person didn't take the time to explain his thought process. This honestly is making it hard to enjoy math or even learn. This book is going in the trash. Multiple typos. Numbers coming out of nowhere with no explanation in some sections. This was a highly frustrating experience and I wouldn't recommend this book to anyone. In some areas, it will show you formulas or even an example problem that you don't even use until the next or even a few sections. It's obvious that this book was not proofread. I know whoever made this put in a little work, but... this book just isn't it.
