Answer:
We need to examine the natural numbers.
The natural numbers are the counting numbers,
1, 2, 3, 4, 5, 6, ...
The number 1 is neither prime nor composite.
All natural numbers greater than 1 are either prime or composite.
A prime number is a number that has exactly two factors, itself and 1.
A composite number has more than 2 factors.
A composite number is a natural number greater than 2 that is not a prime number.
Examples:
Prime: 2, 3, 5, 7, 11, ...
Composite: 4, 6, 8, 9, 10, 12, ...
