For any "pre-math" or "quick study" course in mathematics for computer technology students.This complete math text for computer technology students presents the essentials of mathematics in an interesting and easy-to-understand manner. The first seven chapters begin at the very beginning--with fractions and decimal numbers--and then proceed to establish a solid foundation in algebra, trigonometry and logarithms. The four remaining chapters cover computer-related mathematics, including digital number systems and codes, logic gate functions, Boolean algebra and binary arithmetic.

A quick study/review guide in mathematics for anyone interested in computer technology.

**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.
