If we define "opposite" as the additive inverse, the sum is zero.

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!

Opposite numbers are numbers such that their sum is equal to 0 So the opposite number of -98 is 98

The answer is simply 0!

They equal zero.

zero pair

If by "opposite" you mean "additive inverse", the sum is zero. For example, 5 + (-5) = 0.

the opposite of a sum is the difference

Because that is how the opposite is defined!

This is not the case. The word opposite can be defined many ways mathematically, but generally indicates either the additive or multiplicative inverse. In most cases, opposite is defined as the addictive inverse. Thus, the sum of a number and its opposite is 0, based on the definition of opposite.

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:

Zero can be expressed as the sum of any two opposite mixed number.

The opposite of a number can be itself when its the sum of two numbers and we only be switching the positions of inputs and the order is changed. The opposite of opposite of negative number is opsitive number Okay!

I assume you mean the additive inverse. The sum of any number and its additive inverse is zero. For example, 7 + (-7) = 0.

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).

It can be any number in the range (0, 360) degrees.between

Because the opposite of 8 for example is -8 and 8+(-8) = 0

Additive inverse. For any number, a, there exists a number, -a, so that a + (-a) = 0.

Because that is how its additive inverse is defined!

Opposite of the sum is not a mathematical expression and I can only assume it means the difference.So,5x - x < |x - 5|Or 4x

sum of a quantity means simply that you add things up. For example the sum of 2,3 and 4 is 9 and the opposite is -9

Yes, by definition, always. e.g 4 + -4 = 0

Because the put the opposite #'s on the opposite side

Light as in the opposite of dark? Then it would be "Sum lux." "Ego sum lux" is also appropriate. Light as in the opposite of heavy? Then it would be "Sum levis" (or "Ego sum levis)."
