A factorial is when a number has an exlamation point after it so it represents all the positive integers leading up to that number then you multiply to solve the factorial.
For example: 6! = 6 X 5 X 4 X 3 X 2 X 1 = 720

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.
What is 42 as a quotient of two factorials?
For any pair of factorials, a! / a-1! = a. In this instance: 42! / 41! = 42
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.
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...:)
Is factorial same as permutation?

How find the excluded value of x for a polynomial expression?
Use 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.
Wap to check a number is strong number or not?
