The answers in my answer book don match the textbook. Whats the matter?
Although books sometimes can be defective, the problem is most likely a result of differing editions, especially in the case of curriculum materials such as Saxon or Alpha & Omega. This problem can occur when a textbook is reused with younger siblings. If a new edition of the text has come out in the meantime, when you purchase a new set of student materials it may not match the text book that you used in a past year. Unless it is the first edition of a text, the edition number is normally printed on the cover of the textbook under the title, for example: Second Grade Math, third edition. If you don’t see an edition mentioned on the cover, check on the copyright page, which is found right after the title page. The edition will be found printed in italics under the copyright date.
