Let's say there's Diya. And let's say there is Sal. And let's say that Imran, on any given day, he always has the fewest amount of calories, and Sal, on any given day, always has the most number of calories. So on a given day, we can always say Diya eats at least as much as Imran. And then we can say Sal eats at least as much, not just to repeat those words, as Diya. And so we could set up a little inequality here. On a given day, we could write that Imran's calories on a given day are going to be less than or equal to Diya's calories on that same day, which is going to be less than or equal to Sal's calories on that same day.
