For this question, we need to solve our expression of a plus b plus c.
00:06
And we have been given all of our variables.
00:09
So all we need to do is substitute them in and then solve.
00:13
So we would substitute our a over here, b here, and our c over here.
00:21
So when we rewrite it, it'll look like this.
00:24
We have 12 ,897 plus 36 ,000.
00:32
75 plus 7 ,038.
00:36
So in order to solve this, we need to just write it, write the numbers on top of each other.
00:43
That way we can add much easier.
00:50
So it looks like this.
00:53
And then i'm going to just erase all the extra numbers.
00:59
So when we add, we start from our right column and we go towards our left.
01:04
So we'll start with our far far right, which is 7 plus 5 plus 8...
