Basically, a difference of temperatures is defined by subtracting the next value of temperature and previous temperature.
You may also calculate the range/span of temperatures which is defined as an absolute value of subtracting two temperatures, which gives positive number or zero.


To solve this example are needed these knowledge from mathematics:
