Question

the mathematical value of 0! is what?

Answer 1

1

Answer 2

It's 1, isn't it?
Due the fact that
\[\Large n! = n(n-1)!\]
And just take n = 1

Answer 3

You get
\[\Large 1! = 1(1-1)! = 1\cdot 0! \]

Answer 4

yeah I thought it equaled 1 but wasn't sure

Answer 5

It does... either by convention, or something else ^_^

Answer 6

cool, thanks
