Fuck the real numbers. Numbers are an abstraction.
Zero is a “real” number. Negative 5 is a “real” number.
But have you ever seen zero apples or sailed on negative 5 boats? Uh uh no you haven’t. They are not real.
In reality there’s only existence or nonexistence, it could be a thing or it could not be anything at all, though the latter is actually impossible.
All other things are then not the same as that. If you line them up you can make statements like this thing is not that thing.
This is basically the succession function, and we’re already ahead of ourselves.
From there on we can start inventing more abstractions by using Peanos axioms, but it’s all abstractions, because the second axiom state that something is the same as something, and nothing in reality is ever the same as something else.
It’s all made up. Reality does not have numbers at all.
If your math uses numbers it’s not real math.
Technically Real math only uses numbers.
No
I believe it was a joke where real maths refer to maths dealing with real numbers.
