Prealgebra & Introductory Algebra, Fifth Edition

A Complete Pathway from Arithmetic to Algebra

Prealgebra & Introductory Algebra, Fifth Edition, brings two connected stages of developmental mathematics into one coherent textbook. Elayn Martin-Gay begins with the foundations — whole numbers, place value, rounding, estimation, multiplication, division, and the order of operations — then carries readers into integers, algebraic expressions, and the properties used to solve equations. From there, the text moves through fractions, mixed numbers, decimals, ratios, proportions, and percent before introducing graphs, geometry, measurement, introductory statistics, probability, inequalities, exponents, polynomials, factoring, and rational expressions.

What the Fifth Edition Covers

The chapter sequence is built for steady progress rather than isolated topics. Arithmetic skills reappear inside algebraic contexts, and algebraic ideas are introduced only after the needed numerical groundwork. Students work with linear equations in one variable, formulas, percent applications, square roots, the Pythagorean theorem, congruent and similar triangles, linear measurement, weight and mass, capacity, temperature conversions, polynomial operations, factoring strategies, and rational equations.

How the Material Supports Practice and Review

Review is woven throughout the book. Integrated reviews appear at strategic points, while each chapter includes a group activity, vocabulary check, chapter highlights, chapter review, “Getting Ready for the Test” section, chapter test, and cumulative review. This repeated cycle of instruction, practice, and assessment helps learners identify gaps before moving ahead. The opening chapter also includes study skill tips for success in mathematics, a practical feature for students returning to math or building new study habits.

Who This Textbook Serves

This Pearson fifth edition is designed for developmental mathematics courses that combine prealgebra and introductory algebra. It can also serve as a structured reference for adult learners, tutors, and anyone who wants a clear review of arithmetic and beginning algebra. The explanations and exercise sets assume no advanced background, making the text accessible to students who need to strengthen core skills before college-level algebra or further quantitative coursework.

Why the Combined Approach Works

By treating prealgebra and introductory algebra as one continuous path, the book reduces the disconnect that can occur when students move from arithmetic into symbolic reasoning. Concepts such as fractions, decimals, and percent are not left behind; they become part of equation solving and problem solving. The result is a textbook that emphasizes both procedural fluency and the confidence to apply mathematical ideas in new contexts.
