**Michael Sullivan’s** time-tested method focuses scholars at the primary abilities they wish for the path: *preparing *for type, *practicing *with homework, and *reviewing* the ideas. The **Enhanced with Graphing Utilities Series**has developed to fulfill today’s direction wishes by means of integrating using graphing calculator, active-learning, and know-how in new how one can support scholars be triumphant of their path, in addition to of their destiny endeavors.

Notice that we converted the decimal to its fraction form. Consult your manual to see how your calculator does this. 10 CHAPTER R Review Figure 9(b) If we use the “pretty-print” option on a TI-84 Plus graphing calculator, we get the results in Figure 9(b). Now Work PROBLEMS 57 AND 65 4 Work with Properties of Real Numbers The equal sign is used to mean that one expression is equivalent to another. Four important properties of equality are listed next. In this list, a, b, and c represent real numbers.

Figure 10 also 1 1 shows the points associated with the rational numbers - and and with the 2 2 irrational numbers 12 and p. The real number associated with a point P is called the coordinate of P, and the line whose points have been assigned coordinates is called the real number line. Now Work O Ϫ3 Negative real numbers 0 –12 1 –32 2 Zero 11 The real number line consists of three classes of real numbers, as shown in Figure 11. Figure 11 Ϫ2 Ϫ 3–2 Ϫ1Ϫ 1–2 PROBLEM 3 Positive real numbers 1. The negative real numbers are the coordinates of points to the left of the origin O.
