110 Chapter 1 The Set of Real Numbers Group Activity Evaluating Formulas Using a Calculator Materials: A calculator Estimated Time: 15 minutes Group Size: 2 In this chapter, we learned one of the most important concepts in mathematics—the order of operations. The proper order of operations is required whenever we evaluate any mathematical expression. The following formulas are taken from applications from science, math, statistics, and business. These are just some samples of what you may encounter as you work your way through college. For Exercises 1–8, substitute the given values into the formula. Then use a calculator and the proper order of operations to simplify the result. Round to three decimal places if necessary. 9 5 1. F C 32 (biology) C 35 F 95 nRT P 2.
