Meaning of Multiplication and Division in Physics

In summary: So, for example, if you're studying the behavior of a mass in a gravitational field, then you would use the units of kilograms (or meters if you're measuring in space) to do your calculations.

A question that gets my mind going in ever decreasing circles is "what is it about three that allow it to be applied to so many quantities?" . There's a 'threeness' that is outside the physical world. We do our three times table but when we explain it to a child we talk about three apples and four boxes of three apples etc.

I haven't the reference material on hand, but isn't it "One, Two, Many, Lots" ?
