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

Answer 1

Nathan Axel

See below.

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#
