Chapter Opener
InterAct Math tutorials provide you with online practice problems and guided solutions.

Once you've practiced and mastered the measures in this chapter, think about how you can apply these skills to real data. Refer back to page 513, the first page of Chapter 10, in your Basic Mathematics textbook and review the football yardage application.

Here's your chance to explore the World Wide Web and practice your new skills at the same time. Being sacked for a loss of yardage in the chapter opening application, Kordell Stewart, like many NFL quarterbacks, experiences positive and negative yardage plays in the course of a game. A quarterback's loss in yardage is expressed with negative numbers, but how is the yardage recorded for the defensive end who makes the tackle? Visit some related Web sites to find out about recent football games, including offensive and defensive play highlights, player statistics, and the latest NFL news.

After you've practiced and after you've explored, don't forget about your upcoming Chapter Test. Prepare for your exam by working through our Chapter 10 Review, and then check your answers. These free downloadable files are accessible by selecting the Chapter Review button at the top of this page.

Good luck!
