why is 0! 1?
(By seeing these questions everyday i can answer it from CPhill's help)
I haven't got a proper answer to this but...
5! = 6!/6
4! = 5!/5
3! = 4!/4
2! = 3!/3
...
So,
0!= 1!/1
That's exactly the way I would have "proved" it too, MathsGod1 .....!!!!!
Very nice work !!!!!
Excellent answer MG :D
