3. Two integers whose sum is zero are called additive inverses of each other.

4. a) 10
b) 10

5. a) Hint with the help of an example:
Consider an integer 5.

Its additive invers is -5
Difference between an integer and its additive inverse = 5 – (-5)

=> 5 + 5 = 10
b) Hint with the help of an example:

(i) – 4 – (-3) = -4 + 3 = – 1
(ii) – 6 – (-9) = – 6 + 9 = 3
