For sale is my College Algebra (4th Edition) textbook by Beecher, Penna, and Bittinger. If you are a current student at UMUC, then you already know how horrible some of the "free" textbooks are. In short, this textbook was instrumental in helping me succeed in MATH 107 and Math 108. If you are planning on taking MATH 009, MATH 012, MATH 106, MATH 107, or MATH 108, then you need this textbook! Call or text.
