If it is 2 degrees outside and the temperature will drop 15 degrees tonight , how cold will it get?

Answers

-13 Just do 2-15 or put it on a numeral line

Final answer:

The temperature will drop 15 degrees tonight, resulting in the temperature being 13 degrees below zero.

Explanation:

To find out how cold it will get, we need to subtract the temperature drop from the current temperature.

In this case, the current temperature is 2 degrees and the temperature will drop 15 degrees. So, we can calculate: 2 - 15 = -13.

Therefore, it will get 13 degrees below zero tonight.
