> to describe apples, bananas and everything countable
An apple is an abstraction over the particles/waves that comprise it, as is a banana.
Euclid is no more abstract than the day to day existence of a normal person, hence to claim that it is unusually abstract is to ignore, as you did, the abstraction inherent in day to day life.
As I pointed out it's very possible to create formal reasoning systems which are not symbolic or abstract, but due to that are we to assume constructing or studying them would not be a mathematical exercise? In fact the Pythagoreans did all sorts of stuff like that.

No, you don’t understand what abstraction is. Apple is exactly arrangement of particles, it’s not abstraction over them.

Who talks about him being unusually abstract (and not just abstract)?

How am I ignoring this abstraction when I’ve provided you exactly that (numbers are abstraction inherent in day to day life).
I’m sorry but you seem to be discussing in bad faith.
> Apple is exactly arrangement of particles, it’s not abstraction over them.
No. You can do things to that apple, such as bite it, and it is still an apple, despite it now having a different set of particles. It is the abstract concept of appleness (which we define . . . somehow) applied to that arrangement of particles.
