Answer:
All right. So this next question says to give an example from your life experience of adding to negative numbers. Well, uh, I feel like, um well, at least in my life where I'm sure the supplies to a lot of you guys. Well, I'm a student, and as a student, I use a lot of notebook paper, So I'm sure a lot of you guys do as well. Ah, and I like to get these spiral bound, You know, one subject notebooks with, you know, some some number of sheets of paper in them is like 70 or 100 or something, right? So I like to keep track of how many pages I've used, So I know when I need to get a refill. Um And so maybe for one class, let's say I have for one class, I I use three pages for one class and then for another class I used, like, maybe five pages are This is over the course of, like, a week or a few days or something. So if I use three pages and five pages, uh, from my notebook, while the number of pages left Well, if I'm taking out pages from the notebook. I'll be I'll be. You know, technically, these will be negative numbers, so I'm, you know, I'm using or I'm taking. You know, I'm minus ing three pages or I'm taking three pages. So if I were to use three pages and five pages for two different classes, will you can represent that with adding, you know, the amounts that a used together. So if I, you know, use three pages, I have a negative three, and then I have negative five pages for my next class. So I add those two together. And so if we want to figure out how many pages I've used in Total, well, let's go ahead and let's let's mark out our stuff here. So plus or minus, um, let's use for our plus. Here are Let's go ahead and represent positive integers with Let's just Say like red rectangles and negative integers with blue rectangles. So in this case, are negative. Three. Here my minus three pages is Ah, I've used three pages, so that's gonna be in blue. And for my minus five pages, that's also in blue those air, both negative integers. So if I were to you know, say, use these and, uh, use all of these pages. I would have to add these two losses together. So if I were to represent negative three with rectangles, let's just say we have blue rectangles. Let's represent negative three with three blue red rectangles and each blue rectangles for a negative one. And if I had five blue rectangles here for negative five, each rectangle being negative one. So if we add these together, if we're gonna add negative three and negative five, it be the same as adding three blue rectangles and five blue rectangles together. So, uh, since these are the same color, they're the same sign together. We can actually, you know, just go ahead and we can add them just as they are, since they are the same color or the same sign. So let's go ahead and do that. We have three plus five, five plus three, or or in any any direction you want. So five plus three, that'll give us eight. So now we need to consider which color that eight is. In this case, it's blue since we're adding blue rectangles together here, so we get positive eight. And so uh, sorry. My bed. We get negative eight. So if I were to use three pages on one subject and five pages on another, I'd use the total. Ah, I would use the total of eight pages, or I would have eight pages less.
