# 4 meaning math 4! means “4 factorial”, which means 4 x 3 x 2 x 1 = 24. Likewise, 7!, or “7 factorial”, means 7 x 6 x 5 x 4 x 3 x 2 x 1 = 5040. n!, or “n factorial” (where n is a positive integer) is the product of all of the positive integers from 1 through n, both inclusive. n! = n *.

Answer. It's the factorial sign (!). 4! simply means that we are taking the product of 4×3×2×1. See some examples below: 1! = 1. 2! = 2×1 = 2. 3! = 3×2×1 = 6. 4! = 4×3×2×1 = 24.

In mathematics, a square root of a number x is a number y such that y² = x; in other words, a number y whose square (the result of multiplying the number by itself, or y ⋅ y) is x. For example, 4 and −4 are square roots of 16, because 4² = (−4)² = 16.
