This thing. They want us to add together. Positive eight and negative 10. Well, they're opposite signs, so we're going to have to subtracted the smaller, absolute value from the bigger, absolute value. But that gives us two. And now we picked the sign of the bigger number that's done and sign is negative. So negative two is our answer, okay?

This time they want us to add the number negative five and positive 12 together. Well, they're opposite signs. So what we should do is attract the smaller number, absolute value from the bigger number and so 12 minus 47 and then take the sign of the bigger number. But the bigger number is 12 and it's positive, So positive. Seven is our answer Cool.

This time they want us to add the numbers negative for and I get have 11. And while they're the same sign So the last number should have the same sign in the end. But we're gonna add their absolute value. Used to give it well, four plus 11. You know that it's gonna be 15 so we're gonna have a negative 15 as our answer.

This time they want us to have the numbers 12 and negative 16 together. Wrong. They're opposite signs. So we're gonna use the sign of the bigger number. Bigger helps it. Really? That's extinct. So the negative and what we're gonna do, we're gonna take the absolute value of the bigger one and subtract. Yeah, I was to value smaller one. And while 16 subtract So we know how to do that. We're gonna get afford. So negative for is our answer Well.
