Question:

Sally lives in Antarctica. In the afternoon she measures the temperature to be -4 Celsius degree. Eight hours later she measures the temperature to be $6358_w53_h14.png$. Three hours later she measures again and finds it to be $1688_w53_h13.png$. The following morning she measures one last time and finds the temperature to be $9152_w44_h13.png$. What is the absolute value of the difference between the lowest and highest measured temperatures?

Explaination

The highest measured temperature is $9152_w44_h13.png$. The lowest measured temperature is $1688_w53_h13.png$. The difference between the lowest and highest temperature is -23 - (-2), and the absolute value of the difference between the lowest and highest temperature is $1809_w304_h19.png$.
