What is the additive inverse of \((-9)\)?

Answer and explanation

Correct answer: 9

The additive inverse of a number is the number that gives a sum of 0 when added to the original number. Here, \((-9)+9=0\), so the additive inverse of \((-9)\) is 9. \(\frac{1}{9}\) is its multiplicative inverse, not its additive inverse. Exam tip: to find an additive inverse, change the sign of the number.
