ViviThe additive inverse of a number is the value that, when added to the original number, results in zero. In this case, the additive inverse of x - y would be -(x - y) or -x + y. This is because when you add x - y to its additive inverse, you get (x - y) + (-x + y) = x - y - x + y = 0.

What is the additive inverse property?
An element x, of a set S has an additive inverse if there exists an element y, also in S, such that x + y = y + x = 0, the additive identity.
What is the difference between multiplicative inverse and additive inverse?
The multiplicative inverse of a non-zero element, x, in a set, is an element, y, from the set such that x*y = y*x equals the multiplicative identity. The latter is usually denoted by 1 or I and the inverse of x is usually denoted by x-1 or 1/x. y need not be different from x. For example, the multiplicative inverse of 1 is 1, that of -1 is -1.The additive inverse of an element, p, in a set, is an element, q, from the set such that p+q = q+p equals the additive identity. The latter is usually denoted by 0 and the additive inverse of p is denoted by -p.
The opposite or additive inverse of 88 is?
The additive inverse of 88 is -88; the additive inverse of -88 is 88. The additive inverse can be though of as the solution of a + x = 0, for any number a.
What is the inverse of y equals x?
The inverse of the function y = x is denoted as y = x. The inverse function essentially swaps the roles of x and y, so the inverse of y = x is x = y. In other words, the inverse function of y = x is the function x = y.
Why is the additive inverse of a positive number always negative?
The short answer is because of the definition. A longer answer is: Start of with a negative number X whose additive inverse is Y. SUPPOSE Y is not positive. Then X + Y is one negative, X, less another number that is at most 0, Y. So their sum is less than or equal to X. That is, X + Y is at least as negative as X (and possibly even more negative). But if Y is the additive inverse of X then, by definition (of additive inverses), X + Y MUST be 0. That is a contradiction. So somewhere down the line there is an incorrect supposition. The only supposition above is that Y is not positive. So that supposition must be incorrect. Therefore Y is positive.
