Additive inverse is #+0.5#

Multiplicative inverse is #-2#

ADDITIVE inverses add to make #0#.
They have the same number, but opposite signs:

For example: #(-3) + (+3) = 0#

In this case #(-0.5) + (+0.5) = 0#

The MULTIPLICATIVE inverse is the same as the RECIPROCAL.

The product of a number and its multiplicative inverse is #1#

#2/3 xx 3/2 = 1#

In this case #-0.5 = -1/2#

#-1/2 xx-2/1 = 1#
