Forgotten Algebra

This updated book is a self-teaching brush-up course for students who need more math background before taking calculus, or who are preparing for a standardized exam such as the GRE or GMAT. Set up as a workbook, Forgotten Algebra is divided into 31 units, starting with signed numbers, symbols, and first-degree equations, and progressing to include logarithms and right triangles. Each unit provides explanations and includes numerous examples, problems, and exercises with detailed solutions to facilitate self-study. Optional sections introduce the use of graphing calculators. Units conclude with exercises, their answers given at the back of the book. Systematic presentation of subject matter is easy to follow, but contains all the algebraic information learners need for mastery of this subject.
