Understanding the Fact: 3! = 3 × 2 × 1 = 6 A Simple Yet Powerful Math Explanation Everyone Should Know Factorials often appear in mathematics, especially in permutations, combinations, and probability — but few concepts are as fundamental and intuitive as 3!, read as “three factorial,” which equals 6. Whether you’re a student just starting out or a professional seeking a quick recap, understanding that 3! = 3 × 2 × 1 = 6 opens the door to deeper mathematical insights. ### What Is a Factorial? A factorial is a mathematical operation used to calculate the product of all positive integers from 1 up to a given number n. Formally, for any integer n ≥ 1, n! = n × (n − 1) × (n − 2) × ... × 2 × 1 When n = 0, by convention, 0! = 1, and for n < 0, factorials are undefined. ### Breaking Down 3! Let’s apply this to 3 factorial: 3! = 3 × 2 × 1 - First, multiply 3 by 2: 3 × 2 = 6 - Then multiply the result by 1: 6 × 1 = 6 So, 3! = 6 — simple, yet powerful.
