The high temperature for the day is 28°F. The record low for the day was −12°F.

what difference does it make?

To find the temperature range for the day, you subtract the record low temperature from the high temperature.

Step 1: Subtract the record low temperature from the high temperature.
28°F - (-12°F) = 28°F + 12°F = 40°F

The temperature range for the day is 40°F.

To find the range of temperatures for the day, you need to subtract the record low temperature from the high temperature.

In this case, the high temperature is 28°F and the record low is -12°F. To calculate the range, you subtract -12 from 28:

28°F - (-12°F) = 28°F + 12°F = 40°F

So, the range of temperatures for the day is 40°F.
