Question

Write a pair of positive integers, a pair of negative integers, one positive and one negative integer whose sum is $-5$

Answer 1

Pair of positive integers

Sum of two positive integers is always a positive number. So It is not possible to get $-5$ as sum of two positive integers.

A Pair of negative integers

Lets take$-2$ and $-3$ as two negative integers

The sum will be

$-2+(-3)=-2-3=-5$

One positive and one negative number

Lets take$2$as a positive integer and $-7$as a negative integer

then sum will be $2+(-7)=2-7=-5$
