Similarly one may ask, what is a factorial in math?
In mathematics, the factorial of apositive integer n, denoted by n!, is the product of all positiveintegers less than or equal to n: For example, The value of 0! is1, according to the convention for an empty product.
One may also ask, what does an exclamation mark mean in math? In mathematics, the symbol represents thefactorial operation. The expression n ! means "the productof the integers from 1 to n ". For example, 4! (read fourfactorial) is 4 × 3 × 2 × 1 = 24. (0! is definedas 1, which is a neutral element in multiplication, not multipliedby anything.)
