This makes the math easy for me. They explain it in a way that just works for me. I didnt have any problems at all. Plenty of practice in each section so you can apply what you're learning as you go. And as you go, they start to teach you various methods of calculations so you can go with whichever works for you. 5 stars.

For school

Format: Paperback, Format: Paperback

This book was required for my program. It’s exactly what I needed. The only thing is it came in a bag and not a box so the front cover got a little bent. There are also some gray spots on the side of the book. Other than that it’s in good condition and is fine for school.
