The additive inverse of a number A is a number B that gives a result of 0 when added to A. The multiplicative inverse of A is a number B that gives a result 1 when A and B are multiplied.

Here A = 3 + 4i, the additive inverse is -3 - 4i and the multiplicative inverse is `1/(3 + 4i)`

The additive inverse of 3 + 4i is -3 - 4i and the multiplicative inverse of 3 + 4i is `1/(3 + 4i)`
