Yes

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' Dayna,a 10 year old girl

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.

For any pair of factorials, a! / a-1! = a. In this instance: 42! / 41! = 42

by using the Gamma method apparently...:)

Just about anywhere. The trick is figuring out who's curious and having the nerve to do something about it.

YES!

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.

29 days. Nice little trick to figuring this out: if the year is divisible by 4, February has 29 days. (1972/4=493)

No, because division is not an associative operation.

No. Simple permutations are composed of 2 factorials.

Use factorials.
