Find the sum of the opposite of -18 and its additive inverse? - Answers

The additive inverse of -18 is +18.Hence if you want to add them,Remember the additive inverse of a negative number will be its positive.Its simple, just remove the negativity symbol. So -5 additive inverse is +5.And for a positive number just put a negativity symbol in front of it. :D.Hence +10 will become -10.Remember the additive inverses always add up to give zero!!Therefore you can always use this way to find the answer of your question.Let the additive inverse of -18 be X.As the law states, they add up to 0-18 + X = 0X = 0- (-18)X = 0+18X = 18Coming to the next part of your question,the opposite of -18 is simply the additive inverse!!!Therefore its 18!!Hence18+18=36!Hope that helps buddy!!
