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!!
Hence
18+18=36!
Hope that helps buddy!!

Taigathe opposite of negative 18 is positive 18. It's just like absolute value. |-18| is 18 because 18 is 18 steps away from 0 so is -18 like how it is 18 away from 0 and not -18 away from 0. -18 away from 0 is not a thing. So therefore, the opposite of negative 18 is positive 18 because the opposite of negative is postitve.

What is the additive inverse of 6?
-6. The additive inverse of a number is the number, that, when added to the original number, causes it to equal zero. You can kind of think of it like an opposite number. So, the additive inverse of 2 is -2, and -4 is 4.
What is the sum of any rational number and its opposite?
If we define "opposite" as the additive inverse, the sum is zero.
What is the additive inverse of .5?
The additive inverse for a number is its negative value. The sum of an integer and its additive inverse is zero. For the example (5), the additive inverse would be (-5).
What is the additive inverse of 6 plus 4i?
The additive inverse of 6+4i is -6-4i since their sum is 0. It is analogous to real numbers where the additive inverse of 6 is -6 since 6+-6 =6-6=0 In the case of complex numbers, we add them by adding the real parts and then adding the imaginary parts. So to find the complex additive inverse of a+bi, we find the inverse of a which is -a and of bi which is -bi and so the additive inverse is -a-bi
The sum of a number and its additive inverse is equal to?
Zero. For example, the additive inverse of 5 is -5, and 5 + (-5) = 0.
