As a mathematician you are free to name the number two as you want. *polite* mathematician, or just those who want to be as simple as possible will try to use the more standard notation. naming 3 by "xx" could be confusing in that respect. > (because Peano said so?) There is no authoritative argument in math. There are fashion, prejudice, stubbornness and many human things like that, but nobody serious in math will believe something because the boss said so.
