What does this mean 4!

Question

Its math and i dont get what this ! has to do with math

Answer 1

i can't be exact, but i can give examples

4! is equal to 4 x 3 x 2 x 1 or 24

5! is equal to 5 x 4 x 3 x 2 x 1 or 120

and so on and so forth

what ever number is placed before the "!" symbol is multiplied by every other whole number below it, meaning no zero or negative numbers

Answer 2

in math "!" is shorthand for "factorial."

so "4!" is "four factorial" which means:

4! = 4 x 3 x 2 x 1 = 24

5! = 5 x 4 x 3 x 2 x 1 = 120
