The lowest temperature ever recorded in the state of Oregon was54°F (in Seneca, on February 10, 1933). The state’s record high temperature occurred in Pendleton on August 10, 1898, when it reached 119°F. What is the historical temperature range in the state of Oregon?

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 (-54 degrees, right?), your problem will look like this:

119 - (-54) = range

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