Find the additive inverses of the following integers:

6, 9, 123, –76, –85, 1000.

Additive inverse property:

Case 1: If x is positive number, x+(-x)=0. So, (-x) is called as additive inverse of x.

Case 2: If x is negative number, -x+(-(-x))=0. So, (x) is called as additive inverse of x.

According to the above property,

The additive inverse of 6 is (-6).

The additive inverse of 9 is (-9).

The additive inverse of 123 is

(-123).

The additive inverse of -76 is 76.

The additive inverse of -85 is 85.

The additive inverse of 1000 is

(-1000).
