Question

The temperature at noon on a winter day was 8°C. At midnight, the temperature had dropped 15°C. What was the temperature at midnight?

Answer 1

All you have to look at is the word "dropped" and you know it's a subtraction problem. In this case, it would be 8 - 15.

8 - 15 = -7

It would be -7°C at midnight. I hoped this helped! :)
