All right, so in this question, we're going to be simplifying the expression negative 32 plus 24 plus negative 6 plus 10.
00:09
So we have four numbers here, and let's first go ahead and represent them in terms of our colored rectangles here.
00:17
So we'll use red rectangles to represent positive numbers and blue rectangles to represent negative numbers.
00:23
So in this case, our positive numbers are going to be 24, that's a positive, and our 10 here is also positive.
00:32
Our negative numbers are going to be negative 32 and negative 6.
00:38
So now we have all of those done.
00:40
We can go ahead and we can draw them out.
00:41
So let's start with our blue numbers here.
00:44
We have 32, which will give you 32 blue squares, our blue rectangles, and six blue rectangles over here.
00:53
On our positive side, we have 24 blue rectangles and 10 blue rectangles.
01:00
So first, let's go ahead and combine light colors.
01:03
When you combine light colors, you don't really have to worry about any cancellations here.
01:08
So we can add these numbers as they are.
01:10
So 32 plus 6, we can go ahead and do that straight away.
01:13
So we'll put it over here, 32 and plus 6.
01:17
So that'll give us a 8 and a 38.
01:22
So that'll be blue, that's negative.
01:24
So we'll end up with 38 blue squares on this side.
01:29
And for red, we have 24 plus 10.
01:32
We can add those as they are.
01:34
24 plus 10 right here...
