Question.  13

The additive inverse of a negative integer

(A)

is always negative

(B)

is always positive

(C)

is the same integer

(D)

zero

Detailed Answer with Explanation:

  • The additive inverse of a number is the number you add to it to get 0.

  • Let the negative integer be (a).

  • So, (a<0).

  • By definition, we need a number (x) such that

  • (a + x = 0).

  • Solving for (x):

  • (x = -a).

  • Since (a<0), multiplying by (-1) flips the sign:

  • (-a>0).

  • Therefore, the additive inverse of a negative integer is positive.

  • Example: If (a=-7), then its additive inverse is (-a=7) (positive).
