Zero: prime or composite
Author: carl w gamauf
Is zero a prime or composite number?
Response #: 1 of 1
Author: tee
The usual definitions for prime and composite numbers restrict us to the
positive integers so zero is neither prime nor composite. Even if we were
to expand our universe to include the natural numbers (non-negative inte-
gers) the usual definitions (check their statements carefully) would exclude
zero.
