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 = 0
X = 0- (-18)
X = 0+18
X = 18
Coming to the next part of your question,
the opposite of -18 is simply the additive inverse!!!
Therefore its 18!!
Hope that helps buddy!!
