NOTE TO THE READER

This is not an ordinary book. The pages are numbered in the usual way, but they are not read consecutively. You must follow the directions which you find at the bottom of each page.

You will find that reading this book is very much like having an individual tutor. The book will continually ask you questions and correct errors as well as give you information.

Your progress through this course will depend entirely on your ability to choose right answers instead of wrong ones-and by your endurance. The course is divided into chapters, and a number of short learning sessions produces better results than a few long ones.

Follow the instructions and you'll find it's impossible to get to the final page without mastering the fundamentals of Algebra.
