A temperature measurement from earths stratosphere is taken as -70 degree Fahrenheit. The temperature on the earths surface below is found to be 41 degrees Fahrenheit. Find the difference between the surface temperature reading and the stratosphere temperature reading.

41 - 70 = -29

I think Ms Sue took the sum of the two temperatures instead of their difference

41 - (-70)
= 41 + 70
= 111 degrees

I goofed, Thanks, Reiny.

To find the difference between the surface temperature reading and the stratosphere temperature reading, we simply subtract the two temperatures.

The surface temperature is given as 41 degrees Fahrenheit, and the stratosphere temperature is given as -70 degrees Fahrenheit.

The difference is calculated by subtracting the stratosphere temperature from the surface temperature:

41°F - (-70°F) = 41°F + 70°F = 111°F

Therefore, the difference between the surface temperature reading and the stratosphere temperature reading is 111 degrees Fahrenheit.
