Film Camera Lenses How Does The Numbering System For Camera Lenses Work?

How does the numbering system for camera lenses work? - film camera lenses

I am looking for a camera, and I do not understand the numbering system for lenses. They have separated two by a hyphen, I've seen it all, 28-40 and 70-200, and all sorts of things in between. Can someone explain?

Even though everyone knows, the same number is applied to lens the film too?
