Write the additive inverse of each of the following: (i) 28 (ii) 59 (iii) 109 (iv) 213 (v) 1910

Additive inverse of a is -a, since a + (-a) = 0
In the same manner:
(i) Additive inverse of 28 is -28
(ii) Additive inverse of 59 is -59
(iii) Additive inverse of 109 is -109
(iv) Additive inverse of 213 is -213
(v) Additive inverse of 1910 is -1910
