A whole number that can be made by multiplying other whole numbers.

Example: 6 can be made by 2 × 3 so is a composite number.

But 7 can **not** be made by multiplying other whole numbers (1×7 would work, but we said to use **other** whole numbers) so 7 is **not** a composite number, it is a prime number.

All whole numbers above 1 are either composite or prime.
