The temperature of a freezer started at 18 degrees Celsius. After cooling for a few hours, the freezer had a temperature of -12 degrees Celsius. What is the difference between the new, colder temperature and the original temperature?

Step-by-step explanation:

Difference = New temperature - original temperature

                  = -12 - (18)

                 = - 30

New temperature is 30° less than the original temperature
