What is the additive inverse of 3?

What is the additive inverse of 3 and how do you calculate the additive inverse of 3?

The additive inverse of 3 is the number that when added to 3 will equal 0. Here is the equation to solve the problem where x is the additive inverse of 3:

3 + x = 0

When we solve the equation above for x, we get x = -3. Thus, the answer to "What is the additive inverse of 3?" is -3.

Additive Inverse of 3 = -3

The two addends in an addition equation are interchangeable, which means that the answer to "What is the additive inverse of -3?" or "What is the additive inverse of negative 3?" is 3.

Since the additive inverse of 3 is -3, additive inverse is also known as the opposite number. To get the additive inverse of a postive number you put a minus in front of it and to get the additive inverse of a negative number, you remove the minus to make it a positive number.

This also means that the double additive inverse of 3 is 3, because you add the minus and then remove it again.
