Prealgebra (2nd Edition)

This clear, accessible treatment of mathematics features a building-block approach toward problem solving and realistic, diverse applications. The Putting Your Skills to Work and new chapter-end feature, Math in the Media, present readers with opportunities to utilize critical thinking skills, analyze and interpret data, and problem solve using applied situations encountered in daily life. The goal of the changes in the 2nd edition is to upgrade the level of algebra in the book—This is accomplished by introducing equations, evaluating expressions, and properties of exponents earlier and revisiting the topics more often. Readers now learn how to solve equations using one principle first (Chapters 1, 3, 4, and 5)—Using both principles together is covered (Ch. 6) after readers have had substantial practice using one principle of equality. Contains 2 chapters dedicated to algebra skills (Ch. 3 and 6). A substantial increase in coverage of evaluating expressions (nearly double) from the first edition. Signed numbers are now covered earlier in Chapter 2 and Whole number operations are covered in one chapter vs. two in the previous edition.
