## Summary

This text from the author team of Aufmann and Nation offers the same engaging style and support for students as the Aufmann College Algebra series, all in a brief format that covers the entire course in a single semester. Interactive learning techniques incorporated throughout the text help students better understand concepts, focus their study habits, and achieve greater success. In this First Edition, the authors have also integrated many components into the textbook to help students diagnose and remediate weak algebra skills. Extra support also comes from the Aufmann Interactive Method, featuringTry Exercisesthat allow students to practice math as it is presented and to more easily study for tests. Prepare for the Next Section Exercisesappear at the end of exercises and are specifically written to review prerequisite skills the student will need in the next section. Answers at the end of the text and a reference section help students review if they get a wrong answer. Review Notescover prerequisite skills to help students without the necessary knowledge to understand important concepts. These example-specific notes direct students to the appropriate pages where they can practice and review the skill, thus decreasing frustration and increasing success. Interactive Reading Support Questionsengage students in learning mathematics and encourage them to think critically. Visualize the Solutiongraphics are often paired withAlgebraic Solutionsto assist visual learners in understanding concepts. Focus on Problem Solvingfeatures at the beginning of each chapter review then demonstrate various strategies used by successful problem solvers. Eduspace,Houghton Mifflin's online learning tool powered by Blackboard, is a customizable, powerful and interactive platform that provides instructors with text-specific online courses and content.
