This book was designed as an introductory trigonometry textbook for college students with the explicit goal of reducing textbook costs.

This textbook is intended for adult learners who wish to review and improve their algebra skills. The content covers all the ABE outcomes for the Algebraic Math - Advanced Level. The concepts are explained concisely, but with enough depth to provide students with the background necessary for success in college or university level mathematics. The ample number of examples and exercises makes this text a great resource for students as well as for instructors.

This textbook is a concise, understandable, and effective guide on intermediate level mathematics. This book can be used by Adult Basic Education programs at colleges; students in community colleges, high schools, tutoring, or resource rooms; self-study readers, including new teachers to brush up on their mathematics; professionals as a quick review of some basic mathematic formulas and concepts; and by parents to help their children with homework. In this book, each topic, concept, term, and phrase has a clear definition followed by examples. It acts as a concise study guide, quickly getting to the heart of each particular topic, helping students with a quick review before doing mathematics homework or preparing for tests. Key terms, definitions, properties, phrases, concepts, formulae, rules, and equations are easily located, and it provides clear step-by-step procedures for applying theorems and solving word problems, using realistic real-world application examples. In addition, each unit has a self-test that allows students to test their understanding of the material. Students can also take the self-test before beginning the unit to determine how much they know about the topic. Those who do well may decide to move on to the next unit.
