�On April 2, 2003, the high temperature in the United Stateswas recorded as 94°F in Wink, Texas. The low temperature for the day was 23°F, recorded in both Deadhorse and Northway, Alaska (at �4°F, Presque Isle, Maine, recorded the lowest temperature in the contiguous states). What was the temperature range in

the United States on that day?

The "range" of anything is the difference (distance, of a sort) between the two. Normally, you'd just subtract, but since one of the numbers you are referring to, I think, is a negative (-4 degrees, right?), your problems will look like this:

94 - (-4) = range in contiguous US
94 - 23 = range in total US

What happens when you have two negatives in a subtraction problem?
