comment How did the rule of addition come to be and why does it give the correct answer when compared empirically?
@bzal "what was the system(or base) of number system developed first, was it decimal, binary or something else?" depends, and something else. Many cultures developed numbers independently. Our modern base 10 system was spread by Arabs and has its origin at India. The Mayans had a base 20 system (complete with concept of 0). Roman numbers position can be taken as addition - they are glorified tally marks - and higher magnitudes has different symbols (I, V, X...). Egyptians also used different symbols for different magnitudes, they had addition and substraction operators, and even fractions.
