Do not agree that this is always true because of two exceptions.

zero and one are not prime but they are also not composite.

Apart from those two, other non primes will be composite

Nope. False statement. What about 1? It has just one factor -- itself.

Most books define the *whole* numbers as the nonnegative integers.

{0, 1, 2, 3, ...}

The prime numbers are:

{2, 3, 5, 7, 11, ...}

The composite numbers are:

{4, 6, 8, 9, 10, 12, ...}

The numbers 0 and 1 are not included in either set.

False

P.S. Even if your book defines the whole numbers the same as the natural or counting numbers (i.e. the *positive* integers), 1 is still not considered composite. Natural numbers that have more than two positive factors are called composite. 1 has only one positive factor. Hence 1 is neither prime nor composite.

Whale numbers are neither prime or composite. But they are dwindling due to whale fishing and other factors.

Agree if the number is greater than 1. A whole number whose only factors are 1 and itself is prime. A whole number with more factors is composite. A whole number greater than 1 must be one or the other.
