    I think you misunderstand the terms ' definition ' and 'prove'.

    You can explain why it 'makes sense' it should be one, but when it comes down it it, it's just defined to be that.

    see, i can prove it but there is always some "bug". maybe it will work for you but for some other person (who has more knowledge of maths) can prove it wrong.

    I mean, like I said there are EXPLANATIONS like this http://www.adonald.btinternet.co.uk/Factor/Zero.html But it is different.

    lots of math people got together and decided, hey this is going to be the way

    but the reason for it , it simplifies many formulas

    so maybe you should ask, whats the reason for the convention, thats a better question,

    it can be proved using Gamma function

    its just a definition, so you cant ask to prove a definition

    or simply using the definition of the n!

    you cant prove for example, that a bachelor is unmarried. its a definition

    "It can be proved using the definition" Hmm, sounds like a proof to me (xD)

    well n! = n * n-1 *...*3*2*1

    but we dont define things just willy nilly. they are usually well good god reasons for it

    While you're at it, prove all the axioms please, umza? And (technically), \[1! = 1 \times 0! \] \[2! = 2 \times 1! \] \[3! = 3 \times 2! \] ... \[n! = n \times (n-1)! \]

    Umza please go learn the definition of 'proof' and come back.

    uzma , what about 0! = 0 * (0-1)! ?

    anyways, i like the binomial series , i think its called pochhammer

    (0-1)! does it work?

    the reason why we have 0! is because we have n choose r = n! / ( n-r)! r!

  37. anonymous

    and when you have r = 0, we have n! / n! 0!

    the actual proof is done using Gamma function

    wait, its false that 0! = 0 * (0-1)!

    oh sorry, i misread the question and thought that you are asking to prove 0 = 1 instead of 0! = 1 lol. its very easy to prove.
