Final answer:

A(-10) represents the additive inverse of 10. The correct answer is (B) The additive inverse of 10, meaning when you add -10 to 10, you get 0.

Step-by-step explanation:

The expression A(-10) likely refers to the mathematical concept of the additive inverse of 10. In mathematics, the additive inverse of a number is what you add to that number to get zero. When we see A(-10), it implies the operation that will undo the addition of 10. Therefore, the correct answer is (B) The additive inverse of 10, which is -10.

For example, if you have 10 apples and you add its additive inverse, which is -10 apples (you take away 10 apples), you will have 0 apples. It is akin to subtraction, where subtracting a number is the same as adding its negative counterpart.

In the context of exponents and powers, as indicated under exponent, a negative exponent reflects an inversion, denoting division rather than multiplication ((A.9)). Similarly, the addition of a negative vector is used to represent subtraction in vector math ((A.12)).
