## Factorial Calculator

The use of the factorial calculator is very simple above. You just need to enter the number that you want to see the factorial of it. After entering the number, click on the 'Calculate!' button to see the factorial of it. If you want to make another factorial calculation, click on the 'Reset' button then reenter a new value.

This calculator will not calculate the values lower than 0.

## What is Factorial?

Factorial is a mathematical calculation that which all the numbers between the 0 and the number that the factorial of it wanted to be calculated are multiplied. For example, the factorial of 4 is denoted as 4!. The factorial is calculated as: 4*3*2*1 = 24. So, 4! = 24. The factorial of a number is shown by an exclamation mark after that number.

## Where the Factorial is Used?

In the mathematical calculations, 'n' different objects are arranged in a sequence. The total number of different arrangements of these n objects can be calculated with the n!.

Another application that factorials are used in is some mathematical theorems such as binomial theorem and Taylor series. In these theorems, factorials appear as denominators.

## Where Can I Use Factorial Calculator?

As we stated above, calculation of the factorials of numbers by hand or by a conventional calculator is very burdensome. And factorials are appearing as intermediate calculations in complex mathematical calculations. So, it will be very useful to have a factorial calculator that you can use to see the factorials of numbers rapidly without losing time by hand calculations.

## Conclusion

The use of the factorial calculator is very simple like above.
