## Introduction to Factorial Calculator with Variables

The advanced factorial calculator with steps is an algebraic free tool that is used to **find the factorial** of a given n positive number. It determines the factorial of the n numbers that are the product of one another and arranges in a set.

Our factorial expression calculator also helps you to calculate the simple factorial, addition, subtraction, multiplication, or division factorial of all kinds of real numbers. It is a valuable tool in statistics to "find combinations and permutations" of integers in a set.

## What is Factorial?

Factorial is the multiple of all **positive integers** between 1 to n numbers of values. It is usually used in probability distribution to find a combination or arrangement of different objects in a set.

It is denoted with exclamation marks with the given number as n!

## Formula Behind Factorial Expression Calculator

The **factorial formula** consists of n real numbers. The online factorial calculator uses the following formula which is as follow,

$$ n! \;=\; n * (n-1) * (n-2) * … * 1 $$

Where,

n!: represents the n number of elements

n (n-1) (n-2): n number of elements multiplied each other and one number is subtracted from the previous number.

## Working Process of Factorials Calculator

The factorial division calculator uses a simple procedure while calculating the factorial of n number of integers. Our tool has an **advanced algorithm** that can solve simple factorial, factorial of two numbers with arithmetic operations.

When you give input to a factorial notation calculator, it identifies the function whether it belongs to simple factorial or factoria with arithmetic operations.

After recognizing the type of given problem it starts calculating the factorial according to the formula of factorial. If you give input of simple factorial then it simply calculates the integer using factorial formula.

If you give input of **addition factorial of two numbers**, then the calculator with factorial finds the factorial of the first number using the formula of factorial and then the second number with the formula and adds the result of both the numbers and you get the solution of adding two factorial.

If the given integer are subtraction of two numbers then the factorial expressions calculator finds the factorial of the first number and second number and then subtracts these factorials to get the subtraction of two numbers.

In the same way for the multiplication of two numbers, the factorial sequence calculator first evaluates the factorial of two numbers separately. Then multiply their factorial answers and obtain a solution of multiplication factorial.

Similarly, in the division, first, it finds the factorial and then **divides these numbers** so that you get the solution of the division of two numbers. Now let's examine an example of factorial with arithmetic operation to understand the working process of the advanced factorial calculator with steps.

## How to Calculate Factorial: An Example

The factorials calculator can solve all the factorial problems but its main purpose is to let you know the step-by-step calculation process. So we are going to provide you with an answer for practicing.

### Example:

Find the following if n = 3 and m = 9.

$$ (n! + m!) $$

**Solution:**

The given values are:

N = 3

M = 9

So,

$$ n! \;=\; 1 * 2 * 3 $$

$$ n! \;=\; 6 $$

$$ m! \;=\; 1 * 2 * 34 * 5 * 6 * 7 * 8 * 9 $$

$$ m! \;=\; 362880 $$

$$ n! + m! \;=\; 6 + 362880 $$

$$ n! + m! \;=\; 362886 $$
