You talk to a friend who lives in a different state. She tells you that today it is 12° below zero where she lives. You tell her it is 54° where you live. What is the difference in temperatures?

66

Step-by-step explanation:

One way of solving this is to first add 12 to get the number to 0. Then add another 54 to get to 54 degrees. Then you can add these two numbers together to get 66.

- 1.613 = -1.6 or -1.61

-1.522 = -1.5 or -1.52

0.587 = 0.6 or 0.59

3.079 = 3.1 or 3.08
