What describes the additive inverse property?

• A. A value that multiplies to 1
• B. A value when added to any number equals 0
• C. The reciprocal of a number
• D. The square of a number

Answer: (B)

Additive inverse means the value that cancels another when you add it. For any number a, its additive inverse is -a, and a + (-a) = 0. This is why the property says every number has a partner that sums to zero. For example, 7 and -7 add to 0, and 0 + 0 = 0. The other ideas describe different operations: multiplying to 1 is the multiplicative inverse (the reciprocal), not about addition; the square of a number is a separate operation.
