In just 12hours on february 21,1918 the temperature in gransville, North Dakota, rose from -33 ^f to 50^f by how much did the temperature change?

just subtract... 50 - -33 = 80 degree temperature change.. enough of a change that you can be ice fishing at one moment then going swimming the next.. maybe, if you're a polar bear.

isnt the answer a negative number?
