The exclamation mark almost always indicates factorial, i.e. n! = 1*2*3*...*n. Therefore 4! would be 1*2*3*4 = 24. Additionally, the exclamation mark can indicate negation, e.g. in computer programming and logic.
How is the exclamation mark used in math?
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.
