What does this symbol in math mean "!"?

Question

example:

4!-11/4???

what does the ! mean???

Answer 1

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

24 - 11 = 13 following orders of operation

Answer 2

it's the factorial symbol.  

n! = n(n-1)(n-2)(n-3)(n-4)..........(3)(2)(1)

in other words, you multiply every number that is below until you reach 1.

so 9! = 9(8)(7)(6)(5)(4)(3)(2)(1)

Answer 3

n!, pronounced "n factorial", signifies the product of the first n positive integers.  For example:

1! = 1

2 ! = 1*2 = 2

...

8! = 8*7*...*1 = 40320

In general, F(n) = n! can be defined recursively by:

F(n) = n*F(n-1), with the initial condition that F(1) = 1.

Also note that F(0) is defined to be equal to 1 by convention.

4! - 44/4 = 4*3*2*1 - 11 = 24 - 11 = 13

Answer 4

factorial  = !

Answer 5

It's called the "factorial".  "4!" is pronounced "Four factorial".  It means to multiply all of the positive integers starting with 1 and going up to the number before the factorial.  So for example:

4! = 4 * 3 * 2 * 1 = 24

3! = 3 * 2 * 1 = 6

Answer 6

FACTORIAL so 4! =4*3*2*1=24-11=13

Answer 7

4!-44/4

=4*3*2*1-11

=24-11

=13

! is called "factorial

4! is pronounced "4 factorial"

it means all numbers starting with 4 and descending one by one down

to 1 are to be multiplied together
