    I wish they would have made it clear that the book is the main source of the information. I did three sections just using the videos. Some of the stats on the test did not match what was in the book. Overall the class was just reading the text book and taking tests.

    I like the self-motivation factor, however I would've liked additional help reviewing for the exams. I found a few of the questions were more in depth conceptual interpretations of basic facts discussed in the topic presentations.

book cover

Elementary Algebra, 6e is part of the latest offerings in the successful Dugopolski series in mathematics. The author's goal is to explain mathematical concepts to students in a language they can understand. In this book, students and faculty will find short, precise explanations of terms and concepts written in understandable language. The author uses concrete analogies to relate math to everyday experiences. For example, when the author introduces the Commutative Property of Addition, he uses a concrete analogy that "the price of a hamburger plus a Coke is the same as a Coke plus a hamburger". Given the importance of examples within a math book, the author has paid close attention to the most important details for solving the given topic. Dugopolski includes a double cross-referencing system between the examples and exercise sets, so no matter which one the students start with, they will see the connection to the other. Finally, the author finds it important to not only provide quality, but also a good quantity of exercises and applications. The Dugopolski series is known for providing students and faculty with the most quantity and quality of exercises as compared to any other developmental math series on the market. In completing this revision, Dugopolski feels he has developed the clearest and most concise developmental math series on the market, and he has done so without comprising the essential information every student needs to become successful in future mathematics courses. The book can be accompanied by numerous useful supplements, including McGraw-Hill's online homework management system, MathZone, which can be purchased separately.
