Represented by an exclamation mark (!), the factorial of a non-negative integer n, denoted as n!, is the product of all positive integers less than or equal to n It plays a crucial role in permutations, combinations, binomial expansions, and more The formula for the factorial is: Factorial of n = n! = n × (n - 1) × (n - 2) × × 1 Examples:
- What is a Factorial? How to Calculate Factorials with Examples
Definition of a Factorial The factorial of a number is the multiplication of all the numbers between 1 and the number itself It is written like this: n! So the factorial of 2 is 2! (= 1 × 2) To calculate a factorial you need to know two things: 0! = 1; n! = (n - 1)! × n

The formula for half factorial is: ${\left( \dfrac{1}{2}\right) !=\dfrac{1}{2}\sqrt{\pi }}$ The half-factorial follows the recursive property of factorials: (n + 1)! = (n + 1) × n! For example, ${\left( \dfrac{3}{2}\right) !=\left( \dfrac{3}{2}\right) \times \left( \dfrac{1}{2}\right) !}$ Double Factorial (n!!)

Factorials are commonly used in probability and statistics, when working with combinations and permutations When you start doing combinations, permutations, and probability, you'll be simplifying expressions that have factorials in the numerators and the denominators
- Factorial - Algebrica
Factorial, denoted as n!, represents the product of all positive integers less than or equal to a non-negative integer, n In simpler terms, given a non-negative integer, the factorial of that number is calculated by multiplying all the positive integers from 1 up to n n! = n × (n − 1) × (n − 2) × … × 2 × 1 = n × (n − 1)!
