Hi, I'm Jimmy Chang, and we're here to talk about how do I calculate averages of positive and negative numbers. Now, regardless of an, of numbers are positive, negative or both, when it comes to calculating averages, it's a pretty consistent pattern. You take the numbers that you have, you add them altogether and then you divide by how many values there are. So, for example, if you have negative three, negative four and one and two and you want to find the average of all those numbers, all you really do is you add all of them together and then you divide by the total number that you see here which is four. So, negative three plus negative four, that's going to be negative seven; one plus two that's going to give you three and negative seven plus three is going to give you negative four. And then, you can take that negative four and divide by how many values there are which are four values and then, you go from there. So, negative four divided by four is going to be negative one. So, the average of these four values is going to be negative one. So, when you're finding the average of positive and negative values, you just follow the rules of finding an average and you'll be good to go. So, I'm Jimmy Chang, and that's how do I calculate averages of positive and negative numbers.
