The "additive inverse" is essentially the negative value. It changes the number in the opposite direction on a number line. If you add a number to a value, and then add its inverse, you will have the same original value.
Example: 2 + 3 = 5 , then 5 + (-3) = 2

The "multiplicative inverse" is the reciprocal of a number (i.e. for x, it is 1/x )
Dividing by a number (especially a fraction) can be done by multiplying its inverse.
Examples:
The division 6 divided by 2 = 3 is the same as 6 times its inverse (1/2), also 3.
The division 9 divided by 3/4 is the same as 9 x 4/3 = 36/3 = 12

How do you find the opposite of a number?
The answer depends on what you mean by "opposite": whether it is the additive inverse or the multiplicative inverse.
What is the sum of an integer and its opposite?
If by "opposite" you mean its additive inverse, the answer is 0. If by "opposite" you mean its multiplicative inverse, for the number x, it will be (x+1/x).
What do you call the opposite of a number?
Opposite sign? Additive inverse.
What is the opposite of nine?
The number (-9) is the additive inverse of 9.Inverse operations can also be used to find the additive inverse of a specific number. For example, -9 is the additive inverse of 9 since the sum of -9 and 9 is 0. Additive inverses come in pairs; 9 is the additive inverse of -9, just as -9 is the additive inverse of 9. Any two numbers are additive inverses if they add up to 0.Visualize a pair of additive inverses on the number line. The number 9 and its additive inverse -9 are both nine units away from 0 but on opposite sides of 0. For this reason, -9 is called the opposite of 9, and 9 is the opposite of -9. The opposite of a number may be positive or negative.
