Question

How do you find the additive and multiplicative inverse of 3?

Answer 1

See below.

Explanation:

The additive inverse is such that for a real number `a`:

`a + (-a) = 0`

The multiplicative inverse is such that for a real number `a`

`a * 1/a = 1`

So for `3`:

Additive inverse is `-3`
Multiplicative inverse is `1/3`
