Natural numbers are naturally used for counting apples (and other things) so they are sometimes called counting numbers. Even some animals other than humans can count and add, so they must be natural. Minus two apples isn't very natural so negative numbers are not included.
Every integer (and its negation) is a divisor of itself. Every integer is a divisor of 0. Integers divisible by 2 are called even, and numbers not divisible by 2 are called odd. 1, â1, n and â n are known as the trivial divisors of n. A divisor of n that is not a trivial divisor is known as a non-trivial divisor. A non-zero integer with at least one non-trivial divisor is known as a composite number, while the units â1 and 1 and prime numbers have no non-trivial divisors.
