Composite Number

Composite Number
A whole number that can be divided evenly by numbers other than 1 or itself.

Example: 9 can be divided evenly by 3 (as well as 1 and 9), so 9 is a composite number.

But 7 cannot be divided evenly (except by 1 and 7), so is NOT a composite number (it is a prime number).

Whole numbers above 1 are either composite or prime.
