    If 0 is not a number, then what is 1° below 1°F ?
    That's nothing, we get -30 C here.

          A label?
          All contrariness aside, zero does have duties to perform. I suspect that long before humans could write that they had first a concept for one, and shortly thereafter, another one and later still yet another one, and at some point in time they gave each a name, and as time went on the added more. Some folks may have stopped at five, but for the most part more numbers were added as needs demanded. Central Americans were the first to sense the value a valueless place holder, then at least a thousand years later, an Asian had the concept before Europeans were aware there were Central Americans and the idea spread slowly. Once it reached Europe, it festered for awhile, and then the concept of standards was conceived, giving a consistency to methods. And the numbers game blossomed, adding negatives, exponents, fractions, errors, not necessarily in this order. Both zero and one are special numbers in a fashion. If a number divided by zero was equal to the number and one was not allowed as a divisor(since it does the same thing to the equation that multiplying by one does) I wouldn't be displeased. But perhaps both zero and one should not be used for multiplication or division. But that would raise other issues, but it might be worth investigating. (by someone else)
