Re: WHAT IS 9 + !0

As offtopic as this is, I need to provide the correct answer:

I am well aware that it has been too long since the time permissed to answer.

Re: WHAT IS 9 + !0

!=Order possibilities.
!0=0!=0
9+0=0

Are you sure, GKA?

Normally you wouldn't put it on the left if that's what you meant.

Also 0!=1.

Nah, i mistaked, i meant 9.

Also, 0!=0, its impossible.

Re: WHAT IS 9 + !0

No, 0!=1. This is information that is very easy to look up.

All of the above definitions incorporate the instance

0! = 1

in the first case by the convention that the product of no numbers at all is 1. This is convenient because:

There is exactly one permutation of zero objects (with nothing to permute, "everything" is left in place).

http://en.wikipedia.org/wiki/Factorial

What About "0!"

Zero Factorial is interesting ... it is generally agreed that 0! = 1.

It may seem funny that in this case multiplying no numbers together results in 1, but it helps simplify a lot of equations.

http://www.mathsisfun.com/numbers/factorial.html

The special case 0! is defined to have value 1, consistent with the combinatorial interpretation of there being exactly one way to arrange zero objects (i.e., there is a single permutation of zero elements, namely the empty set ).

Nothingness will never be 1,   wikipedia sometimes give the wrong info due a stupid myth.

He gave more than one source. It's hard to question the reliability of what he said.

Re: WHAT IS 9 + !0

Stop being obtuse. I gave two sources besides Wikipedia, one of them being Wolfram MathWorld (a pretty reliable source). If you want an additional source, the same definition is given on section 2.3 page 151 of Discrete Mathematics and Its Applications by Kenneth H. Rosen. If you enter it into WolframAlpha it gives you 1 for 0!. There's even a website called zero factorial. They have their own sources. Additionally, the analytic extension of the factorial function, the gamma function, gives a matching result.

This is not a source of any serious disagreement at all. It is widely and essentially completely agreed that the factorial of 0 is 1. You are, very simply, wrong.

Re: WHAT IS 9 + !0

If 1!=1.0=1, then why 0!=0.0=1?

Re: WHAT IS 9 + !0

I'm not sure what you're using a decimal point to indicate there (maybe multiplication?), but there are multiple explanations for why 0!=1 from different perspectives.
1) You can have 0!=1 by definition, allowing you to define all other factorials as n!=n(n-1)! for n in Z, n>0.
2) The set with 0 elements is the empty set. There is one way to order the empty set (even though the ordering is simply nothing).
3) If you take that for any n in Z, n>=0, n!=n(n-1)(n-2)*…*1, then doing this for n=0 would give you a product of 0 factors, which is taken as 1.

Re: WHAT IS 9 + !0

ok so it seems like you guys dont know so
the person who made this topic said 9 + !0 because they were holding shift while making the title, so it made 1 a !

damn you guys suck

So here's why, its 0 but they take it as 1. Nonsense.

Bimps, if he mistaked, he would warn us.

Re: WHAT IS 9 + !0

Do I really need to tell you the reason why the product of zero numbers is 1?

Take a product of n numbers. Now take away each of these numbers by dividing it by them. You are left with a product of 0 numbers after having divided the number by all of its factors. After dividing the number by its factors, the number you are left with is 1. 1 is the product of 0 factors.

Other ways of saying it: 1 is the multiplicative identity. 1 is the product of an empty set of numbers for the same reason 0 is the sum; 0 is the additive identity. This is also the same reason that any number exponentiated to 0 gives 1.

0! is not 0 at all, and this is for very good reasons that are not very complicated.

case: 10 obv

do you even math?

do you even code?

pick the point of view.
