Question

(01.02 MC)Which statement best explains the value of 18 − (−5)? The additive inverse of −5 is +5, so 18 − (−5) = 23. The additive inverse of −5 is −5, so 18 − (−5) = 23. The additive inverse of −5 is −5, so 18 − (−5) = 13. The additive inverse of −5 is +5, so 18 − (−5) = 13.

Answer 1

Hey there! I'm happy to help!

The additive inverse of a number is one that has its sign switched. If you put a - before a number, the sign switches. We put a - before -5, so its sign switches. -5's additive inverse is 5, so this 18+5, giving us 23.

The additive inverse of -5 is +5, so 18 - (-5)=23.

Have a wonderful day! :D
