Acceptable. A book with obvious wear. May have some damage to the cover or binding but integrity is still intact. There might be writing in the margins, possibly underlining and highlighting of text, but no missing pages or anything that would compromise the legibility or understanding of the text.
This 940 page text has 14 chapters. It is written by nine authors who include the traditional algebra topics along with additional algebra problems in geometry, trigonometry, and statistics. This book was designed to help students develop skills in reading and problem solving. The text is well written. The basic idea of the lesson is explained but as students do the problems they find that the problems get progressively more difficult.
Each lesson has 20 to 35 problems which would take most students about two hours to do all of them. Twenty problems would take about an hour. The answers to the odd problems are in the back of the text. There is a chapter self test and a chapter review at the end of each chapter; the answers to these are also in the back of the text.
I used this text for three years to teach 150 students Advanced Algebra. Students who usually did A or B work in a math class would be able to do most of the problems without much help. The other students needed more help to complete the assignment.
I would assign about half of the problems at the end of each lesson as a homework . The next day, any problem that a student did not understand would be put on the black board or displayed with an overhead project by students or myself. Since each lesson depends on the preceding lessons, it was important that the students knew how to do the problems and not just the answers.
