The lowest temperature ever recorded in the state of Oregon was�54°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?

To determine the historical temperature range in the state of Oregon, we need to find the difference between the record high temperature and the record low temperature.
The record high temperature in Pendleton, Oregon, was 119°F, and the record low temperature in Seneca, Oregon, was -54°F.
So, to find the historical temperature range, we subtract the record low temperature from the record high temperature:
119°F - (-54°F) = 119°F + 54°F = 173°F
Therefore, the historical temperature range in the state of Oregon is 173°F.
