Okay, so in this next question, we are translating another phrase into an algebraic expression.
00:05
So our phrase is the sum of negative 10, sorry, the sum of 10 and negative 19 increased by 4.
00:14
So first, it looks like we have a sum here between 10 and negative 19.
00:19
So i think first of all, we're going to be adding these two numbers together.
00:24
But then we're going to increase that by 4.
00:27
So we will add another four onto the end of that.
00:31
So that's going to be our expression here, 10 plus negative 19 plus 4.
00:38
So now that we've translated that, let's go ahead and mark out which numbers are positive, which numbers are negative, and corresponding colors.
00:44
So 10 is positive, that'll be in red.
00:47
4 is also positive, that'll be in red, and negative 19 is negative, so that'll be in blue.
00:53
So we're going to end up having 10 red rectangles and 4 red rectangles.
00:59
And we will be adding those together because of the commutative property.
01:05
We can imagine this as 10 plus 4 plus negative 19.
01:10
So we will be adding the 10 red and the 4 red together.
01:16
And then we will have the standalone...
