This is a Yellow Chart textbook. I didn't like math and didn't use it much, but I would glance at it right before tests. I left it at school or it was just sitting on a shelf at home, so there's some wear and tear. However, there are no markings. It comes with the answer key. I'm open to reasonable price negotiations.
