Question

In the previous problem, Ken predicted a drop in temperature. Explain why a drop in temperature would lead to adding a negative integer.

Answer 1

A drop in temperature means the temperature will decrease. That decrease is represented by a negative integer, which should be added to the previous temperature.

Answer 2

Because a drop in temperature means decrease in temperature therefore, we take an integer with negative sign and added to previous temperature.

Explanation:

Drop in temperature means decrease in the temperature .When the temperature decreases then we take decrease value of temperature in negative integer. Because decrease means the temperature fall down .Hence , the decrease in temperature measure with negative sign .

For example, if we take temperature T= 70°C.

If the temperature decreases by 5°c then the temperature

Decrease in temperature=-5°C

Hence, the temperature T= 70+(-5)=65°C.

Therefore , from example we can say that when temperature decreases by some value in integer . Then ,we get final temperature obtained by adding drop in temperature ( negative integer ) in previous value of the temperature.
