Understanding Factorials in Mathematics

What is a Factorial? The product of all positive integers is defined as the factorial of a non-negative

integer "n". from 1 to "n." For example: 0! = 1

1! = 1 2! = 2 3!

= 6 4! = 24 5! = 120

Factorials are used in mathematics and programming for various calculations and counting tasks.

Here is an example of the Python program for the factorial of a number: def factorial(n):

if n == 0: return 1 else: return n * factorial(n - 1)

# Example usage: number = 5 result = factorial(number) print(f"The factorial of {number} is {result}")
