En -Schaum Elementary Math

preface

For the third time in my career, I have been given the responsibility for revising

one of the late Dr. Barnett Rich’s exemplary texts. In 1987, I revised Geometry, and

in 1993 I revised Elementary Algebra. Although this text (Elementary Mathematics)

is quite distinct from those earlier revisions, Dr. Rich’s keen insights into developmental

mathematics are once again clearly present in this text.

This text is unique in that it begins with a most elementary view of arithmetic,

but progresses through a thorough review of arithmetic, algebra, and geometry,

finally introducing the reader to trigonometry. All important principles are stated

in clear, crisp language, leading students who may have less than a substantial background

in elementary arithmetic and algebra through a thorough set of tutorials in

secondary level mathematics.

I have reorganized portions of the book, and I have introduced modern terminology

and the calculator throughout. It is my hope that I retained Dr. Rich’s fine

sense of pedagogy as I have made these revisions.

As always, I thank the fine editorial staff at McGraw-Hill for their assistance,

especially Maureen Walker. My warmest thanks are offered to Jean (Mrs. Barnett)

Rich for her friendship and warm support throughout this revision and prior work

as well. Finally, I dedicate this book to my son, Reed Schmidt, whose love of

mathematics continuously encourages me as a mathematics educator.

DR PHILIAP. SCHMIDT
