Each chapter in the Practice Workbook leaves two problems open for you to solve before checking your reasoning. Use the links below only after attempting the problems. Each page restates the prompt, offers a short diagnostic hint, and links back to the chapter companion.
Complete answers remain in Appendix G of the Practice Workbook. The chapter companion pages carry further reading, self-check quizzes, and hands-on activities.
