Distance is always positive or zero, so we have Ȋa Ȋ Ն 0 for every number a. Remembering that Ϫa is positive when a is negative, we have the following definition. Definition of Absolute Value If a is a real number, then the absolute value of a is a if a Ն 0 Ȋ a Ȋ ϭ Ϫa if a Ͻ 0 Ά 20 CHAPTER P Prerequisites Example 7 Evaluating Absolute Values of Numbers (a) Ȋ3Ȋ ϭ 3 (b) ȊϪ3Ȋ ϭ ϪÓϪ3Ô ϭ 3 (c) Ȋ0Ȋ ϭ 0 (d) Ȋ œ2ෆ Ϫ 1Ȋ ϭ œ2ෆ Ϫ 1 Ósince œ2ෆ Ͼ 1 ⇒ œ2ෆ Ϫ 1 Ͼ 0Ô (e) Ȋ 3 Ϫ pȊ ϭ ϪÓ3 Ϫ pÔ ϭ p Ϫ 3 Ósince p Ͼ 3 ⇒ 3 Ϫ p Ͻ 0Ô ■ When working with absolute values, we use the following properties.

Find its gas mileage. ■ Thinking about the problem. Let’s try a simple case. If a car uses 2 gallons to drive 100 miles, we easily see that 100 gas mileage ϭ ᎏᎏ ϭ 50 mi/gal 2 So gas mileage is the number of miles driven divided by the number of gallons used. 5 in the formula. 9 mi/gal. Example 5 Finding a Formula for Area (a) Find a formula for the area of a rectangle whose length is twice its width. (b) A manufacturing company requires a rectangular sheet of metal whose length is twice its width and whose total area is 50 ft2.
