Let me circle that in orange. All the way to t is equal to four, which is right over here. So this is, one way to think about this is that this is going to be the area above the t axis and below the graph of g. So it's going to be this area right over here that is above the t axis and below the graph of g of t. But we're not going to add to it this area because this area over here, I'll shade it in yellow, this area I'm shading in yellow over here, this is going to be negative. Why is it going to be negative? Because we want the area that is above t and below g. This is the other way around. This is below the t axis and above the graph of g. So one way to think about it is we could split it up. So we could, actually let me just clear this out so we have more space.
