Question 116349: The lowest temperature ever recorded in the state of Oregon was -54F (in Seneca, on Feb 10, 1933) The state's record high temperature occurred in Pendleton on Aug 10, 1898, when it reached 119F. What is the historical temperature range in the state of Oregon?

I think this is what the problem is looking for you to do:
.
At the low end the temperature has always been equal to or greater than -54 degrees F.
.
At the high end the temperature has always been equal to or less than 119 degrees F.
.
So the temperature has always been in the range from -54 to +119 degrees Fahrenheit
(inclusive -- meaning that the range includes -54 and +119).
.
You can express this in the form of a trichotomy inequality:
.
-54+%3C=+t+%3C=+119
.
where the numbers are understood to be in units of degrees Fahrenheit and this
inequality
says that the temperature has always been between the two limits ... bigger than or equal
to -54 and less than or equal to +119.
.
Hope this helps you to understand the concept of range.
