(a) Write a pair of negative integers whose difference gives 8.
(b) Write a negative integer and a positive integer whose sum is -5.
(c) Write a negative integer and a positive integer whose difference is -3.

Solution:

An integer is a number with no decimal or fractional part, from the set of negative and positive numbers, including zero.

a) Let us have - 2 and -10

Difference = - 2 - (-10)

= - 2 + 10

= 8

b) Let us have -10 and 5

Sum = -10 + 5

= - 5

c) Let us have - 2 and 1

Difference = - 2 - 1

= - 3
