The answer is simply 0!
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 property states that if you add a number and it's opposite the sum is zero. copy-ed from "ashby" your welcome C:
Yes In fact, the sum of ANY 2 angles of a square (or a rectangle) is 180o
What exactly do you mean when you say "the opposite of a whole number" . . .
If the opposite is meant to be the additive opposite and not the multiplicative opposite, then their sum is zero. The reason is that is what defines an additive opposite!
If we define "opposite" as the additive inverse, the sum is zero.
Additive inverse. For any number, a, there exists a number, -a, so that a + (-a) = 0.
It can be any number in the range (0, 360) degrees.between
It can be any number in the range (0, 360) degrees.between
The sum of a number and its negative (additive inverse) is zero. For any nonzero value n, n + (-n) = 0
Zero can be expressed as the sum of any two opposite mixed number.
Opposite numbers are numbers such that their sum is equal to 0 So the opposite number of -98 is 98
If by "opposite" you mean "additive inverse", the sum is zero. For example, 5 + (-5) = 0.
Zero
The answer is simply 0!
They equal zero.
