I don't believe this to be true.

2+3

What I see about from a mathematical point of view is two things,
and an operator that acts upon those things.

The OO point of view is that 2 is an object and that the plus
sign is a method of this object and that 3 is the argument of
this method.

The OO point of view is *nothing like* the mathematical point 
of view.

In math, operators and numbers are two different things and the
former don't "belong" to later.
