Let me do that in another color. What does that mean? That means that we're going to start at negative 31, and we're going to move 29 to the right. We're adding 29, so we're going to move 29 to the right. So maybe that gets us right about there. I'm trying to draw an arrow of length I can draw a cleaner looking arrow than that. I'll do it right over here, actually. So then we're going to move 29 over to the right. That's the 29 part. Now this is a positive 29, and so how do we figure out what this is?
This is 29 right here that we're adding. This is going to land us right over here on the number line. So how do we figure out what number that is? Well, once again, we can just visualize it. And eventually you won't have to draw number lines and stuff, but I think it'll be useful here. We're starting at negative We're adding 29 to it, so it's going to make it less negative. But we're still adding less than 31, so we're not going to get all the way back to 0.
We're still going to have a negative number. But how could we figure out the absolute value of that negative number, its distance? Well, once again, that little white part right there, that white part plus this 29, is going to equal 31, if you just think of absolute value, if we don't think about the signs, if we just think about the length.
Or another way to think about it, 31 minus 29 will give us the length of that white part. And of course, it's going to be negative, because the negative number here is larger than the positive number. And we're adding the 2. If we do 31 minus 29, you could borrow and all of that, but that's clearly just going to be equal to 2.
