1. Write a sentence to answer each question:

a. How much warmer is 82 than 40?

The

b. How much warmer is 82 than - 40?

What the answer?

The answers in each case are:

a. 42.

b. 122.

Step-by-step explanation:

In the first case, you should know that the temperature is calculated from the highest temperature to the lowest, in which case:

82 - 40 = 42.

In the second case, when temperatures are negative, you must first bring them to zero and then calculate with the largest positive number, as shown below:

82 + 40 = 122.

1a. 82 is 42 degrees warmer than 40.

1b. 82 is 122 degrees warmer than - 40.

Step-by-step explanation:

1a. 82-40=42

1b. - 40+40=0

0+82=82

82+40 = 122
