Yeah, I'm thinking it can be expressed by numbers, but an expression is a representation, not the actual thing. It is a mental abstraction.

Fairyprincess got me thinking about this in another thread by observing that a 2-D diagram on a sheet of paper isn't really 2-D, because of the 3-D nature of the paper.

Sheet of paper under electron microscope:

A right angle drawn on such a surface is ink saturating a 3-Dimensional landscape, and is only a mental representation of 2-Dimensional reality in a 3-Dimensional one.

The same could be said of a 2-D shape rendered on a computer screen.
