The exclamation mark indicates the operation called "factorial".

'Factorial' is an operation carried out on a whole number. It means: The product

of this whole number with every whole number less that this one, down to ' 1 '.

Examples:

3-factorial = 3 ! = 3 x 2 x 1 = 6

5 ! = 5 x 4 x 3 x 2 x 1 = 120

6 ! = 6 x 5 x 4 x 3 x 2 x 1 = 720

(5 !) / (3 !) = (5 x 4 x 3 x 2 x 1) / (3 x 2 x 1) = (5 x 4) = 20
