Many works are named after objects, such as MacGuffin Title examples, because titles usually emphasize things important to the story.
But sometimes, instead of a singular object, the work is named for a number of objects, like the hypothetical "Three Spheres", a case of Title by Number, which is a Super-Trope of this, because numbers.
But that number gives definition, and implies that the number is important, setting the audience's expectations for a specific number of spheres, instead of more mysterious, One-Word Title, of just "Spheres".
Works that are just Top Ten List, usually have overlap with the 10 section. Running Time in the Title is a Sub-Trope, even by implication, as all times have inherent quantity, so they can be counted, such that an hour is 60 minutes. And on that note, this has a lot of overlap with Time Title, when the amount of the time interval is noted in numbers.
Negative numbers count as their positive versions. Absolute numbers, basically. Also, Episode Zero: The Beginning and Title 1 are about numbers and their relation to the story's timeline. Such entries only go here if they relate to the quantity of an object.
Multiple sequential numbers are grouped into folders, when none of the numbers inside have more than 3 works.
Cases with numbers below 2 are plays on this, due to playing this straight, requiring a plural, while 1 doesn't need a plural, and 0 is really the lack of a quantity.

In nineteen minutes, you can mow the front lawn; color your hair; watch a third of a hockey game. In nineteen minutes, you can bake scones or get a tooth filled by a dentist; you can fold laundry for a family of five. Nineteen minutes is how long it took the Tennessee Titans to sell out of tickets to the play-offs. It's the length of a sitcom, minus the commercials. It's the driving distance from the Vermont border to the town of Sterling, New Hampshire. In nineteen minutes, you can order a pizza and get it delivered. You can read a story to a child or have your oil changed. You can walk a mile. You can sew a hem. In nineteen minutes, you can stop the world; or you can just jump off it. In nineteen minutes, you can get revenge.
