Does 9 exist

Answer 1

That's a question about 'does numbers exist'?

It has been answered in many ways by many mathematical philosophers through history.

Platonics say that numbers exist in a divine world, in which we may get some degreed of insight.

Others say that numbers only exist to humans as a tool.

Others that numbers doesn't exist of all - only the things that numbers represent. Consider the statement "there are nine stones" - there are some stones, but where is nine?

.

So: yes and no - and perhaps.

It depends!
