What is Factorial?
Factorial is a mathematical concept used to represent the product of all positive integers from 1 up to a given number. It is written using an exclamation mark, such as n!. For example, 5! (read as “five factorial”) means 5 x 4 x 3 x 2 x 1, which equals 120. Factorials are commonly used in mathematics, especially in areas like permutations, combinations, and probability, where counting different arrangements or possibilities is important. By definition, 0! is equal to 1, which helps maintain consistency in mathematical formulas. Factorials grow very quickly as the number increases, making them useful in both theoretical and applied fields such as computer science and statistics.
