I find that assumption to be so blatant (much like numbers w/o powers
are raised to first, numbers without signs are positive, 0 is neither
positive nor negative, 1 is neither prime nor composite) to not even be
worth mentioning.

Unless, of course, someone confuses arithmetic mean (average) with
median. Or says 0 is positive, or 1 is prime.

i love math :)
