Hi, I'm Rachel, and today we're going to be going over how to do negative and positive integers. When you have negative and positive integers, you should just thing of the negative integers as subtracting. What does that mean? That means if we have, let's see we have a positive integer of six, plus the negative integer of five. So negative five. That's really the exact same thing as subtracting five from six, six minus five, that's the exact same thing. So the answer is just one, six minus five. You can also have it written the other way, perhaps you have it as negative three plus seven, again, just rewrite it as if it were subtraction, that's the same thing as seven minus three. That can be easier to think about, right? Then negative three plus seven, sometimes we get confused on what that means, but if we just rewrite it like this, seven minus three, we can say oh, well that equals four. That's pretty simple. This is something we're familiar with seeing. So, make sure you always put it into this form. Now if you're doing negative and positive integers and you're multiplying or dividing, and you have one positive and one negative, you're going to multiply or divide just as you were if they were both positive, but then make sure that it's a negative sign, 'cause there's one negative integer. That means that if you have six divided by negative three, the answer is going to be negative two. If you have negative seven times three, one negative one positive, you just multiply them together 21, but then you have to make it negative, 'cause there's one negative. So negative 21, and that's another example of how to use both positive and negative integers. I'm Rachel, and thank you for learning with me today.
