Because if the temperature was 29 degrees in july and in december it was 29 degrees less than 29 then that would be zero because 29-29=0

Rebecca Downs · Answer 2

The temperature went up 29°C, which represents a positive 29. Then the temperature fell 29°C, which represents a negative 29. The average temperature rose and fell the same amount. The absolute values are the same, so the difference is 0.
