All right, so in this next question, we're going to be evaluating the expression p plus q for p is equal to negative 9 and q is equal to 17.
00:11
So first, let's go ahead and we can substitute both p and q into our expression.
00:16
So p plus q is going to be the same as p in this case is negative 9 and q in this case is 17.
00:27
So p plus q is the same as negative 9 plus 17.
00:31
Let's go ahead and figure out what colors or how we're going to represent our numbers.
00:37
So red for positive, blue for negative.
00:39
17 is positive, so we'll represent that with red rectangles.
00:42
Blue is negative.
00:45
Negative 9 is negative, so we will be representing that with blue rectangles.
00:49
Our expression in the end is going to be equal to representing negative 9 with 9 blue rectangles and 17 with 17...
