Additive inverse
Okay kiddo, let's talk about something called additive inverse. Have you ever played with a see-saw or a teeter-totter? Think of numbers as being on a see-saw. Some numbers go up and some go down.
Now, let's say we have a number like 2. If we add something to 2, the see-saw will go up, right? But what if we want to bring the see-saw back down so it's balanced or even? For that, we need to add a special type of number called the additive inverse.
The additive inverse of a number is the number you need to add to it to make zero. So, if we add the additive inverse of 2 to 2, then we'll end up with 0 because they will balance each other out.
For example, the additive inverse of 2 is -2, because when you add them together, you get 0. Or, the additive inverse of 5 is -5, and so on.
So, just remember that the additive inverse of a number is like the opposite number that you need to add to it, so you can balance it out like a see-saw.
