What really is a number?

I know numbers look different to one another, like Daa.........BUT, numbers are used in equations to prove, to SYMBOLIZE, some type of feature of space-time.

Is it possible therefore, "possible", that a number can actually itself alone, a single number, symbolize a FEATURE of space-time?

Like, for instance, what if the number "1" represented a feature of space-time, a line for instance joining two points?

What if the number "1" is a code itself for a mathematical algorithm defining the interaction between two points?
