The concept "circle" itself is an arbitrary definition.
Its intrinsic relations are consequences of that definiton,
and therefore not natural.

It is not the symbols we use to write numbers in, but
the very conept of numbers that's artificial.

Maths is like chess: A logical game with arbitrary rules, who have
lots of complicated and interesting logical consequences, but who
are all based on the arbitrary set of rules.

The difference between the two "games" is that maths helps as a
mental model of the world, e.g.. when you do such things as "count",
or express physical laws (which are real) in mathematical terms
(which is a human symbolism).
