` = n!`

`(n)"Input Number"`

Tags

The Factorial calculator computes the factorial of the input value n.

INSTRUCTIONS: Enter the following:

(n) The number

Factorial: The calculator computes the factorial for n (n!). The Factorial calculator is a prominent feature with other statistical functions in the College Level Statistics Calculator (Stat Calc).

The factorial of n is : `n! = n * (n-1) * (n-2) * ... * 2 * 1`

Example:

`5! = 5 * 4 * 3 * 2 * 1 = 120`

Basic Math Functions:

x^-1: This is the mathematical inverse or reciprocal of x, which is also 1/x
x! : This is the factorial of x
x²: This is the square of x
x³: This is the cube of x
x^y: This is x to the y^th power
10^x: This is ten to the x^th power.
`sqrt(x)`: This is the square root of x
`root(3)(x)`: This is the cube root of x
`root(y)(x)`: This is the y^th root of x
Rand: This returns a random number between 0 and 1.
log(x): This the base 10 log of x
ln(x) : This provides the natural log of x
MOD: This provides the integer remainder of x/y.
