EXAMPLE Solving a Problem Involving Subtraction
The record-high temperature in the United States is 134°F, recorded at Death Valley, California, in 1913. The record low is −80°F, at Prospect Creek, Alaska, in 1971. See FIGURE. What is the difference between these highest and lowest temperatures? (Source: National Climatic Data Center.)
FIGURE
We must subtract the lowest temperature from the highest temperature.
The difference between the two temperatures is 214°F.
The top of Mt. Whitney, visible from Death Valley, has an altitude of 14,494 ft above sea level. The bottom of Death Valley is 282 ft below sea level. Using 0 as sea level, find the difference between these two elevations. (Source: World Almanac and Book of Facts.)
