Answer 1

Step-by-step explanation:

Given:

• Write down pair of integers.

To Find:

1. Sum is –3.
2. Sum is 0.
3. Difference is 2.
4. Difference is –5.

Solution: The pair of integers whose sum is –3 are

➱ (–7) + 4

➱ –7 + 4

➱ –3

★ Pair of integers whose sum is 0 are

➱ (–2) + 2

➱ –2 + 2

➱ 0

★ Pair of integers whose difference is 2 are

➱ (–4) – (–6)

➱ –4 + 6

➱ 2

★ Pair of integers whose difference is –5 are

➱ (–80) – (–75)

➱ –80 + 75

➱ –5
