How to add two whole numbers is a philosophical question?

  You have to define what a "whole number" is first, and that is a philosophical question. You may think it's obvious [1] what a "whole number" is and how it behaves under addition, but to make it formal you have to write it down. Pretty philosophical if you ask me. [1] everyone though that, until a few smart logicians showed up in XXth century and proved everyone else wrong.
