How do nutrition labels even work?

Question

I have a bottle of flavored water (0.68 cents at Wal-Mart, because I’m worth it) and it has 3 servings. If you drink 1 servings worth, you get exactly 0 calories and 0% everything else. But if you drink all 3 servings, you get 10 calories and about 10mg of sodium. How is that possible? I know there’s sometimes really small amounts of things like sodium, but isn’t that usually denoted as “<0%”?

Anything under a certain amount can be left off the nutritional label. This is why ketchup doesn’t list cockroaches as an ingredient, even though they regularly end up in the batches.
