Answer 2

There are adding opposites and multiplying opposites,,,,,,

Explanation:

There are two types of 'opposite' numbers, it depends which operation your are referring to.

Opposites are usually called 'inverses'.

ADDITIVE INVERSES (adding opposites) add up to `0`

They have the same value, but opposite signs,

`(-3) + (+3) = 0`. They are additive inverses.
`(+14) + (-14) = 0`. They are additive inverses.

MULTIPLICATIVE INVERSES multiply to `1`.
They are known as multiplying opposites, or reciprocals.

`3/5 xx5/3 = 1`

`-2/7 xx-7/2 = 1`

They have the same signs, but one has been inverted (flipped).
