We're looking at some of the aggregate operators in this video. So let's start by looking at line five. This is a list of integers that has some numbers going from low numbers to high numbers. And then I'm using several of the aggregate operators here. This is the sum operator. It computes the sum of the sequence, so it'll total all the items that are in the list of integer. I'm sure you can guess what this does. It creates the average of those numbers. And then here, I'm chaining together two of the query operators. I'm using average, but before I call average, I am using another operator called take, and that allows me to take some of the items from the beginning of the sequence, the start of the sequence. This says take the first four, so it's going to take these four items and then calculate the average. In the second…
