Introductory Algebra, 13th Edition

Algebra becomes easier to navigate when each new idea has a clear place in the larger picture. Introductory Algebra, 13th Edition takes readers from number skills and expressions through equations, graphs, polynomials, factoring, systems, radicals, and quadratic equations, building a broad foundation in beginning algebra along the way.

Its guided-learning approach pairs explanations with practice, review, and applications. The result is a structured course text for students who want to strengthen core skills and see how algebraic ideas connect.

Build the foundations before moving ahead

The opening just-in-time review revisits prerequisite topics such as factors, fractions, decimals, percents, and order of operations. The chapters then develop real numbers and algebraic expressions before progressing into equations and inequalities. Skill reviews throughout the text revisit earlier material at points where it supports new concepts.

Follow algebra from expressions to equations

The nine chapters cover solving equations and inequalities; graphing linear equations; operations with polynomials; factoring and quadratic equations; rational expressions and equations; systems of equations; and radical expressions. Later material returns to quadratic equations, including completing the square, the quadratic formula, applications, graphs, and functions.

Applications and problem-solving sections bring mathematical ideas into contexts such as motion, percent, and right triangles. Reviews, chapter tests, and cumulative reviews give learners recurring opportunities to revisit what they have studied.

A guided route through beginning algebra

Guided solutions and step-by-step exercises support readers as they work through problems, while visualizing and translating features draw attention to graphs and mathematical language. Appendixes provide additional reference material, including higher roots, sets, and mean, median, and mode.

Designed for beginning algebra coursework, this textbook can also help independent learners or returning students work systematically through essential algebra topics. Its progression from prerequisite review to quadratic equations makes it useful for studying one concept at a time while keeping the larger course sequence in view.
