We conclude that he difference between the high and low temperature is 23F
How to get the difference between the high and low temperatures?
Here we know that for the given thermometer the highest temperature is 20 degrees Fahrenheit, while the lowest temperature is -3 degrees Fahrenheit.
To get the difference between the high and low temperatures we just need to take the highest temperature and subtract the lowest one, so we will get:
20F - (-3F)
Remember the rule of signs (-)*(-) = (+)
Then:
20F - (-3F) = 20F + 3F = 23F
We conclude that the difference between the high and low temperatures is 23F
