That would be zero. For a number "X" to be its own additive inverse, that would mean: X = -X
Zero.
0 is its own additive inverse. There is no multiplicative inverse for 0.
The additive inverse of a number is the value that, when added to the original number, results in a sum of zero. In this case, the additive inverse of 22 would be -22, as 22 + (-22) equals zero. The additive inverse is essentially the negative version of the original number.
One example would be a Galois Field size 4 (ie GF(4)). Here, the elements are {0,1,2,3} and every element is its own additive inverse.
zero is its own opposite. 0 + -0 = 0
Absolute values are never negative. The opposite, or negative, or additive inverse, of a negative number is the number's absolute value; a non-negative number is its own absolute value. The absolute values of 7 and -5, are, respectively, 7 and 5.
The number that is its own "additive inverse" is zero. (x + 0 = x - 0)For the multiplicative inverse (1/x), the number 1 is its own inverse (also -1). (x times 1 = x/1)x = 1/x is only true where x = 1 or x = (-1)

No, it is one of two numbers that has its own multiplicative inverse which is an integer. The other number is -1.
Since the inverse of a function is it's reflection over the line x=y, which has a slope of 1. The only way a function can be It'a own inverse is if it is a liner function whose slope is perpendicular to the line. Since a perpendicular line is any line with the negative recoprocal of the slope, any linear function whose slope is -1 will be it's own inverse. - stefanie math 7-12 teacher
Assuming the question is about the multiplicative inverse, the answer is, -1. It is its own multiplicative inverse.
