Best-selling author Nigel Cook's new second edition of Introductory Computers Mathematics provides a complete math course for those learning computer technology. Employing an “integrated math applications” approach, this book reinforces all math topics with extensive applications to show readers the value of math as a tool. Specific chapters in the section on Basic Math discuss fractions; decimal numbers; positive and negative numbers; exponents and the metric system; algebra, equations and formulas; geometry and trigonometry; and logarithms and graphs. Computer Math topics cover analog to digital, number systems and codes, logic gates, Boolean expressions and algebra, binary arithmetic, and an introduction to computers and programming. For individuals preparing for a career in computer technology.

From the Back Cover:

After 12 textbooks, 23 editions, and 20 years of front-line education experience, best-selling author Nigel Cook has written this text as a complete math course for computer technology students.

This finely tuned, carefully tested, and accuracy checked volume is organized into two parts. The first seven chapters in Part A begin at the very beginning with fractions and decimals, and proceed on to establish a solid foundation in signed numbers, exponents, the metric system, algebra, trigonometry, logarithms, and graphs. The following six chapters in Part B are devoted to computer mathematics, including analog to digital conversion, digital number systems and codes, logic gates, Boolean algebra, binary arithmetic, and computers and programming.

As with any topic to be learned, the method of presentation can make a big difference between clear comprehension and complete confusion. Employing an "integrated math applications" approach, this text reinforces all math topics with extensive applications to show the student the value of math as a tool. Therefore, if the need for math is instantly demonstrated, the tool is retained.

New to This Edition
• Two new chapters have been added to expand on the mathematics needed for computer technology—Analog to Digital and Introduction to Computers and Programming.
• Numerous mini-math applications have now been integrated into the material so that the student can immediately witness the practical applications of mathematics.
• A Companion Website at www.prenhall.com/cook has an additional bank of questions that further tests student understanding.
• The end-of-section self-test evaluation points list the objectives and a set of questions that test the student's level of comprehension. The cheek-box design invites students to take an active role in monitoring their progress.
• Margin terms highlight key terminology as it is introduced.

INTRODUCTION

Since World War II no branch of science has contributed more to the development of the modern world as electronics. It has stimulated dramatic advances in the fields of communication, computing, consumer products, industrial automation, test and measurement, and health care. It has now become the largest single industry in the world, exceeding the automobile and oil industries, with annual sales of electronic systems greater than \$2 trillion. One of the most important trends in this huge industry has been a gradual shift from analog electronics to digital electronics. This movement began in the 1960s and is almost complete today. In fact, a recent statistic stated that, on average, 90% of the circuitry within electronic systems is now digital, and only 10% is analog. This digitalization of the electronics industry is merging sectors that were once separate. For example, two of the largest sectors or branches of electronics are computing and communications. Being able to communicate with each other using the common language of digital has enabled computers and communications to interlink, so that computers can now function within communication-based networks, and communications networks can now function through computer-based systems. Industry experts call this merging convergence and predict that digital electronics will continue to unite the industry and stimulate progress in practically every field of human endeavor.

Mathematics is interwoven into the very core of science, and therefore an understanding of mathematics is imperative for anyone pursuing a career in technology. As with any topic to be learned, the method of presentation can make a big difference between clear comprehension and complete confusion. Employing an "integrated math applications" approach, this text reinforces all math topics with extensive electronic and computer applications to show the student the value of math as a tool; therefore, if the need is instantly demonstrated, the tool is retained.
