Developmental Mathematics, Third Edition
by D. Franklin Wright
Providing a smooth transition between arithmetic and algebra, Developmental Mathematics emphasizes reasoning, problem solving, and the connections between foundational concepts. The course starts with a coverage of arithmetic and geometry before introducing negative numbers. Once a firm grasp of real numbers is established, the course transitions into common algebra topics such as solving linear equations and inequalities, factoring equations, and more. The new edition begins with an updated Strategies for Academic Success chapter, focusing on study skills, time and stress management, and tips for success in a collegelevel math course.
Each chapter is complemented by two projects that highlight the practical aspects of mathematics, helping students establish connections with key concepts through realworld applications.
Additionally, the extensive exercise set selection classifies questions into Practice, Application, and Conceptual categories. A software question bank expansion with this edition provides even more problemsolving opportunities and ensures a comprehensive understanding of course content.
