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!!
the 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.
What is the additive inverse of eighteen?
The additive inverse of 18 is -18. The additive inverse of any number is the opposite of that number, such that the sum of the original number and the additive inverse is zero.
What is the sum of any number and its opposite?
I assume you mean the additive inverse. The sum of any number and its additive inverse is zero. For example, 7 + (-7) = 0.
What is the sum of a number plus its opposite?
If by "opposite" you mean "additive inverse", the sum is zero. For example, 5 + (-5) = 0.
What is the sum of an integer and its opposite?
If by "opposite" you mean its additive inverse, the answer is 0. If by "opposite" you mean its multiplicative inverse, for the number x, it will be (x+1/x).
What is the opposite of nine?
The number (-9) is the additive inverse of 9.Inverse operations can also be used to find the additive inverse of a specific number. For example, -9 is the additive inverse of 9 since the sum of -9 and 9 is 0. Additive inverses come in pairs; 9 is the additive inverse of -9, just as -9 is the additive inverse of 9. Any two numbers are additive inverses if they add up to 0.Visualize a pair of additive inverses on the number line. The number 9 and its additive inverse -9 are both nine units away from 0 but on opposite sides of 0. For this reason, -9 is called the opposite of 9, and 9 is the opposite of -9. The opposite of a number may be positive or negative.
What is the sum of a fractional number and its additive inverse?
0. By the definition of "additive inverse", the sum of ANY number and its additive inverse must be 0.
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 do you call two opposite numbers whose sum is zero?
These are often called "opposite numbers". The more precise term is "additive inverse". For example, the additive inverse of 5 is minus 5.
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).
Why is the sum of a rational number and its opposite always epual to zero?
Because that is how its additive inverse is defined!
What is the additive inverse of 18?
The additive inverse is the sum of two numbers that will equal zero. The additive inverse of -18 is 18.
