If we define "opposite" as the additive inverse, the sum is zero.

0. By the definition of "additive inverse", the sum of ANY number and its additive inverse must be 0.

Number + additive inverse of number = 0, by definition (the additive inverse of a number is that number, which when added to the original number, results in a sum of 0) Number + additive inverse of number = 0, by definition (the additive inverse of a number is that number, which when added to the original number, results in a sum of 0)

Because that is how its additive inverse is defined!

The additive inverse of 18 is -18. The additive inverse of any number is the opposite of that number, such that the sum of the original number and the additive inverse is zero.

The additive inverse for a number is its negative value. The sum of an integer and its additive inverse is zero. For the example (5), the additive inverse would be (-5).

The additive inverse of 41 is -41. An additive inverse is the number that will make the sum equal zero.

It is zero, by definition of additive inverse!

The sum is zero.

The additive inverse of a number is the negative of that number. Given one number, its additive inverse is the number that needs to be added to it so that the sum is zero. Thus: The additive inverse of 2.5 is -2.5 The additive inverse of -7.998 is 7.998

The additive inverse of any number is its opposite. The sum of a number and its additive inverse is 0. The additive inverse of -6 is 6.

The additive inverse of x is -x It is the number that, when added to the original, gives a sum equal to zero.
