to find factorials you just multiply the factorial like this. for example 6!
you would do 6x5x4x3x2. a little trick of mine is to multiply the previous factorial's answer by the factorial you are trying to make's number like this
6!=5!
5!=5x4x3x2
i hope this was helpful'

When would one use factorials?
Factorials are a mathematics application used for combinations and permutations. The real world application of factorials are used to find the probability of certain things.
How find the excluded value of x for a polynomial expression?
Use factorials.
What is 42 as a quotient of two factorials?
For any pair of factorials, a! / a-1! = a. In this instance: 42! / 41! = 42
Is there an equivalent for factorials when dividing?
No, because division is not an associative operation.
Do decimal numbers have factorials?
by using the Gamma method apparently...:)

Do you have to shout factorials?
YES!
Where can one get help with the subject of factorials in mathematics?
There are mathematics forums online where one can ask questions on factorials or one can read information on factorials. Examples of forums are the "Math Forum" and "Math is Fun" forum.

What are the last two digits in the sum of factorials of the first 100 positive numbers?
To find the last two digits of the sum of the factorials of the first 100 positive integers, we can observe that for ( n \geq 10 ), ( n! ) ends with at least two zeros due to the factors of 10 in the factorial (from the pairs of 2 and 5). Therefore, we only need to calculate the sum of the factorials from 1! to 9!. The sum ( 1! + 2! + 3! + 4! + 5! + 6! + 7! + 8! + 9! ) equals 40320, and the last two digits are 20. Thus, the last two digits in the sum of factorials of the first 100 positive integers are 20.
Is factorial same as permutation?
No. Simple permutations are composed of 2 factorials.
Is there a trick to figuring out factorials?
Not realy besides x! = x*(x-1)!. For some things there are approximations but these are only good for small ranges of values and complicated, generaly reserved for factorials of large numbers.
Can the answers of factorials be decimals?
No. Factorials can only be placed on positive whole numbers or 0. For example, 0!, 1!, and 6! are all fine, but 2.5! and (-1)! are not. Since factorials can only be placed on whole numbers, that means you will only be multiplying whole numbers. 100! = 100 * 99 * 98 ... * 1; all those numbers are whole numbers, meaning your answer will be a whole number.
What are the last two digits in the sum of factorials of the first 100 positive integers?
They are 13.
