I have seen several postings on the prime number question.  As I understand
it, a prime number is one which is only divisible by itself and one.  Now,
in many of the postings on this, I have seen "9" or numbers ending in "9"
given as answers.  Last I heard, 9 was divisible by 1, 3, and 9.  What am
I missing, or am I?
