Okay, so let's first tackle this one. And the key when looking at a complex expression like either of these is to look at the big picture structure of the expression. So one way to think about it is let's look at the outside rather than the inside details. So if we look at the outside here, we have the sign of something. So there's a sign of something going on here that I'm going to circle in red or in this pink color. So that's how my brain thinks about it. From the outside, I'm like, okay, big picture, I'm taking the sign of some stuff.
