This is the 8th edition of your textbook. You currently have the 9th edition. You can use this edition as a reference guide to look at example problems. Some of the HW questions are the same. However, some are NOT! They could have different numbers etc. I do not advise that you use this for HW. Rather, you may use it as a reference guide to look up example problems or to read the lessons themselves.
