This is all about (positive) integers.
Some numbers can be written as the product of two other numbers, e.g:$$48=6 \cdot 8$$Such numbers are called composite numbers.

Some numbers can only be written as the product of two numbers if these are 1 and itself:$$7 = 1 \cdot 7$$Such numbers are called prime numbers.

Prime numbers are: 2, 3, 5, 7, 11, 13, 17, 19 etc.
1 is not composite and not prime, because it doesn't fit either of the cases described above.
The rest of the integers are composite.
