Spiral Out: Just think of a number line with the set of natural numbers marked. Start at the point that corresponds to the number one. Then, move 1 to the right, which represents the operation of "adding 1," and you'll end up at the point marked with a 2, the "squiggly line." The operation of addition is essentially sliding along the number line.

Being ignorant of the meaning of these mathematical abstractions does not in any way undermine them. It simply means you have not taken the time to learn mathematics before commenting. It's not just math that has this level of abstraction, so do other subjects, like economics. As an example, the amount listed in your bank account is not a reference to any specific, unique, set of dollar bills.
The number two is an abstraction of exactly what? If you wish to apply the term abstraction to economics, then consider the abstraction of labor-value earned into its money-form.

Synthesis: The labor-value theory in economics has been debunked long ago and so no I will not waste my time trying to argue that a non-empirical value claim is in any sense true. The number 2 is an abstraction that little children learn. They learn what is common about 2 chairs, 2 dollars, 2 houses, 2 women, 2 schools, 2 cars, etc. That's the part that you completely reject.

I've always conceptualised the number two as an abstraction of polar-opposites on a spectrum.

Day and Night
Hot and Cold
Up and Down

Although these things may be unified in reality (all is one), we conceptualise them as two different things to compare, contrast and show the variety within the spectrum.

Biologically speaking, 1+1 might = 3.
