You might be happy to know that 0 is considered a prime element in typical cases (barring those cases where there are 0 divisors, i.e. where two elements can be multiplied to create 0, obviously this is not an issue with regular numbers). Edit: for historical reasons prime elements are slightly different from the usual prime numbers, and 0 remains a bit of a special case even now.
