This factorial calculator helps you calculate any factorial operation which is a function that makes the product of all positive integers less than or equal to a given number. More details on this topic you can read below the form.
How does this factorial calculator work?
This factorial calculator might come in handy whenever you need to solve a math problem or exercise that requires any of the following 5 factorial calculations:
■ Simple operation which takes account of a single given value and applies the standard factorial formula: n! = 1*2*3…*n;
■ Adding, subtracting, dividing or multiplying 2 factorials which is computed by using the same factorial equation for both values and then add OR subtract OR divide OR multiply by case the two numbers obtained.
What is factorial?
In mathematics a factorial is a function that makes the product of all positive integers less than or equal to a desired number (n).
The notation for this function is !, as for instance when we say we need to find the value behind 4 factorial it should be written such 4! and is equal to 1*2*3*4 = 24.
Please take account of the fact that 0! is equal to 1 as there is only one way to permute 0 objects.08 Apr, 2015
