Yes.
No.. if you write 7/2 as -7/2, then that's additive inverse property.
Additive inverse of a number a is that number which on addition with a gives 0.7 is additive inverse of -7.The property shown is additive inverse property because the addition yields 0.
Additive Inverse
The 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 -21 would be 21, as -21 + 21 equals zero. The additive inverse is essentially the negative of the original number, so the additive inverse of -21 is 21.
the additive inverse property states that a number plus it's opposite equals zero. in other words, x + (-x) = 0 example: 5 + (-5) = 0
inverse property of multiplication
-5
The existence, for the number 18, of an additive inverse which is -18.
Zero is the additive identity.
Zero is the additive identity element.
The existence of the additive inverse (of ab).
Well, isn't that just a happy little question! The additive inverse of 11 is -11. You see, when you add a number and its additive inverse together, you always get zero, creating a beautiful balance on your canvas of numbers. Just remember, there are no mistakes, only happy little accidents in the world of mathematics.
