it would be a plus sign, so because inverse, means the opposite, and the opposite of subtraction is addition, so therefore it would be x+y.

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.
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.
What is the inverse of y equals x?
To find the inverse simply switch the x's with the y's so... inverse of y=x is x=y
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 inverse for numbers under addition?
A number and its additive inverse add up to zero. If a number has no sign, add a "-" in front of it to get its additive inverse. The additive inverse of 5 is -5. The additive inverse of x is -x. If a number has a minus sign, take it away to get its additive inverse. The additive inverse of -10 is 10. The additive inverse of -y is y.
What is the additive inverse of 9.1?
We are talking group theory here. A group with addition has an additive inverse. A group with multiplication has a multiplicative inverse. The additive inverse of a number x is a y with x + y = 0. The additive inverse of x is written -x. Hence, the additive inverse of 9.1 equals -9.1. The reason that this question can arise is that beyond groups, there are rings and fields. Rings and fields have, besides addition, also multiplication. An element can have an additive inverse and a multiplicative inverse at the same time.
What do you call integers that add to zero?
Two numbers, which when added together result in zero, are called each other's additive inverse. That is, for two given numbers x and y, if x + y = 0, then y is the additive inverse of x and x is the additive inverse of y.
What are inverse numbers?
An inverse, without any qualification, is taken to be the multiplicative inverse. is The inverse of a number, x (x not 0), is 1 divided by x. Any number multiplied by its inverse must be equal to 1. There is also an additive inverse. For any number y, the additive inverse is -y. And the sum of the two must always be 0.
What additive inverse of-45?
The additive inverse of x is -(x), so the additive inverse of -45 is -(-45), or 45.
What are inversions?
An inverse, without any qualification, is taken to be the multiplicative inverse. is The inverse of a number, x (x not 0), is 1 divided by x. Any number multiplied by its inverse must be equal to 1. There is also an additive inverse. For any number y, the additive inverse is -y. And the sum of the two must always be 0.
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.
What is the inverse property in math?
There are two related identity properties: the additive identity and the multiplicative identity. The additive identity property states that for x belonging to a set, there is an additive inverse in the set, which is denoted by -x such that x + (-x) = (-x) + x = 0, where 0 is the additive identity which also belongs to the set. The multiplicative identity property states that for y belonging to a set, there is a multiplicative inverse in the set, which is denoted by 1/y or y-1 such that y * (1/y) = (1/y) + y = 1, where 1 is the multiplicative identity which also belongs to the set.
Justify that if x plus y equals x plus z then y equals z?
The requirements are that the operation of addition is associative, the existence of an additive identity and additive inverses. Associativity: a + (b + c) = (a + b) + c = a + b + c Identity: The set contains a unique element, called the additive identity and often denoted by 0 with the property that a + 0 = 0 + a = a for all a in the set. Inverse: For each element in the set, x, there exists an element which is its additive inverse. For addition, this is denoted by -x, and has the property that -x + x = 0. x + y = x + z Add the inverse of x to both sides: -x + (x + y) = -x + (x + z) By associativity: (-x + x) + y = (-x + x) + z -x is additive inverse of x, so: 0 + y = 0 + z 0 is additive identity, so y = z
Does y plus -y 0 show the inverse property of addition?
Yes, that's what we mean by "-y" or "negative y" -- it's the additive inverse of y. -y is defined as the number which, when added to y, gives zero. y + -y = 0 (Zero, in turn, is defined as the additive identity -- the number which, when added to x, gives x.)
