Question

In the previous problem, Ken predicted a drop in

temperature. Explain why a drop in temperature would

lead to adding a negative integer.


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 1

Explained below.

Explanation:

First of all, an integer is a whole number that can be either positive, negative or zero.

Now, a drop in temperature signifies a reduction in the temperature.

This means that if for example, the current temperature is 50 °C, a drop in temperature of 10°C would mean that the current temperature would be gotten by subtracting 10 from 50.

Now,current temperature after drop would be;

T = 50 - 10

To prove that it is gotten by adding a negative integer:

This can also be written as;

T = 50 + (-10)

Because from mathematical multiplication signs, minus multiplied by plus gives minus.

Since, T = 50 + (-10), it means that a negative integer of minus 10 has been added to the initial temperature to get the new decreased temperature.
