If a <b>positive integer</b> is not a prime, it is either 1 or a composite number.
1 is considered neither a prime nor a composite number.
The question is:
"if a # is not a prime # what is it?"
A number can be real, complex, positive, negative, or anything else. So the answer depends on to which set the "number" belongs.
