Preface
Many very bright and competent people enrolled in colleges, universities, and community colleges are frustrated. They are eager, ambitious, and quite capable of succeeding in their careers or moving to a better job. They want to learn but find themselves handicapped because they do not have the basic mathematics skills needed to continue. They need help with these essential skills. If that describes where you are, this book is for you.
This book is designed to help you review or relearn basic arithmetic skills. It is more like a private tutor than a lecturer; you participate in the process rather than simply reading, listening, or sleeping through it.
The book is organized in a format that respects your unique needs and interests and teaches you accordingly:
You can use it for self-study , for study with a tutor or helper, or as a text in a formal course.
Each chapter begins with a preview and a sample test to help you see your particular needs.
You have the option of designing your own course, skipping familiar material to save time or working through all of it if you need it.
Many practice problems and self-tests are included, including drill problems, practical applications, more difficult brain boosters, and problems where a calculator should be used. Each chapter ends with an optional self-test .
Answers to all problems are in the back of the book.
Unlike previous mathematics textbooks you may have used, this book is careful to explain every operation. Sometimes we even explain our explanations.
This book has been used by hundreds of thousands of students and they tell us it is helpful, interesting, and even fun to work through. We hope you agree with them.
It is a pleasure for us to acknowledge our debts to the many people who have contributed to the development of this book and to this third edition. Jeffrey Golick and the staff at John Wiley Sons, Inc., have been most supportive and patient throughout the lengthy process of producing a book. We were fortunate to have W. Royce Adams, formerly the director of the Reading Center at Santa Barbara Community College, read preliminary versions of the book and provide valuable assistance in improving its readability.
Finally, we wish to extend special thanks to our kindest critics and most enthusiastic helpers: our children-Pat, Laurie, Maire, and Eric-our other works in collaboration.

How to Use This Book
Image Not Available
Many people go through life afraid of mathematics and upset by numbers. They bumble along miscounting their change, bouncing checks, and eventually trying to avoid college courses or jobs that require even simple math. Most such people need to return and make a fresh start. Few get the chance. This book presents fresh-start math. It is designed so that you can:
Start at the beginning or wherever you need to start
Work on only what you need to know
Move as fast or as slowly as you wish
Skip material you already understand
Do as many practice problems as you need
Take self-tests to measure your progress
In other words, if you find mathematics difficult and want a fresh start, this book is designed for you.
This is no ordinary book. You cannot easily browse in it. You don t read it; you work your way through it. Ideas are arranged step-by-step in short portions or frames. Each frame contains information, careful explanations, examples, and questions to test your understanding. Frames are numbered on the left.
7 Read the material in each frame carefully, follow the examples, and answer the questions that lead to the next frame. Correct answers move you quickly through the book. Incorrect answers lead you to frames providing further information. You move through the book frame by frame, sometimes forward, sometimes backward.
Each major section of the book starts with a preview that will help you determine those parts on which you need to work.
Notice the following symbols designed to help you: CAUTION This symbol points out common errors or misunderstandings that many students have and about which you need to be careful. LEARNING HELP This offers a hint or gives an alternate explanation or different way of thinking about a concept or procedure. This calculator icon tells you to look for a calculator key sequence showing how to solve the problem using a calculator. Calculators are an important tool, and we assume that once you have learned the basic operations of mathematics, you will use a calculator.

Important terms are noted in the margin where they are first used or defined.
Students are led step-by-step through examples and explanations:
Step 1 Many worked examples are given . . .
Step 2 ... with explanations for each step . . .
Step 3 ... and immediate feedback in the text and in and
Most students hesitate to ask questions. They would rather risk failure than look foolish by asking dumb questions. To relieve this worry, we ask and answer these FAQs (frequently asked questions) in the cartoons. Learning the FAQs produces smart students.

Special Topics
As you move through the book, special topics appear within lines like this. Check them out.
In 1846, the Reverend H. W. Adams described what happened when the 10-year-old math whiz Truman Safford was asked to multiply, in his head, the number 365,365,365,365,365,365 by itself. He flew around the room like a top, pulled his pantaloons over the tops of his boots, bit his hands, rolled his eyes in their sockets, sometimes smiling and talking, and then, seeming to be in agony, in not more than one minute, he said 133,491,850,208,566,925,016,658,299,941,583,225. * In this book we will show you a way to do arithmetic that is not so strenuous, quite a bit slower, and not nearly so much fun to watch.
Now, turn to page 1 and let s begin.

If you are certain you can work all of these problems correctly, turn to page 81 for a self-test. If you want help with any of these objectives or if you cannot work one of the preview problems, turn to the page indicated. Super-students (those who want to be certain they learn all of this), turn to frame 1 and begin work there.
