Textbook in PDF format

Developmental Mathematics, Fourth Edition was written to provide a solid foundation in arithmetic and algebra as well as to develop problem-solving skills. It is intended for basic math and introductory algebra courses; however, all of the necessary intermediate topics are included in the appendices for those wishing to extend the course to intermediate algebra. Specific care was taken to make sure students have the most up-to-date relevant text preparation for their next mathematics course or for non-mathematical courses that require an understanding of algebraic fundamentals. I have tried to achieve this by writing a user-friendly text that is keyed to objectives and contains many worked-out examples. As suggested by AMATYC and the NCTM Standards (plus Addenda), real-life and real-data applications, data interpretation, conceptual understanding, problem solving, writing, cooperative learning, appropriate use of technology, number sense, estimation, critical thinking, and geometric concepts are emphasized and integrated throughout the book.
The many factors that contributed to the success of the previous edition have been retained. In preparing the Fourth Edition, I considered comments and suggestions of colleagues, students, and many users of the prior edition throughout the country.
