In mathematics, the exclamation mark is often used to represent the factorial of a number. The factorial of a non-negative integer n, denoted as n!, is the product of all positive integers up to n. For example, 5! = 5 x 4 x 3 x 2 x 1 = 120. The exclamation mark is also used in some mathematical notations to indicate a specific operation or property, such as the subfactorial function.

Why is the factorial sign an exclamation mark instead of any other symbol?

The use of the exclamation mark for the factorial function is often attributed to French mathematician Christian Kramp in the 19th century. He introduced the symbol to represent factorials because it was already commonly used in mathematics to denote "not" or "negation," aligning with the idea of multiplying decreasing positive integers. Over time, the exclamation mark became widely adopted for factorial notation due to its clear and concise representation.
