Which of the following represents the additive inverse of 12?
A. -(-12)
B. 12
C. -12
D. 1/2
C. -12
The additive inverse of a number is a number that, when added to the original number, results in zero. In other words, if you add a number and its additive inverse together, you will get zero.
To find the additive inverse of a number, you simply change the sign of the number. If the number is positive, you make it negative, and if the number is negative, you make it positive.
In this case, the number is 12. So, to find its additive inverse, we need to change the sign of 12.
Therefore, the additive inverse of 12 is -12.
So, the correct answer is C. -12.
The additive inverse of a number is the number that, when added to the original number, gives a sum of zero.
So, to find the additive inverse of 12, we need to find a number that, when added to 12, gives a sum of zero.
The correct answer is C. -12
