The Easy Test Prep series originated in the fact that students simply don't need another textbook on Algebra, Calculus, etc. There are already wonderful textbooks on the market in almost every area of mathematics and science. What struggling students do need are more detailed, worked examples than are normally found in even the best textbooks. To solve this problem, every book in the Easy Test Prep series contains hundreds of problems with both answers and detailed, worked solutions. In this volume, Easy Test Prep: Prealgebra, each of the major concepts in a standard Prealgebra course is given its own section and problems. After a list of the problems for a concept, the answers are given so that students can compare their answers to the correct ones. Following the answers are detailed, worked solutions to each problem. The answers are given first because many students do not want to see a worked solution immediately upon finding that their answer is not the correct one. At the end of the book are two Final Exams that test whether or not the student has grasped all of the concepts in the book. Our sincere hope is that this book will aid you in your goal of attaining both a higher course grade and a deeper understanding of Prealgebra.
