Ответ:
Notice that when we go from 4! to 3! , we divide by 4.
(Because
the 4's cancel)
And when we go from 3! to 2! , we divide by 3, and etc.
We can use this pattern to see why 0! = 1.
And so by following the pattern, we determine that 0! = 1
-------------------------------
Note:
There are no factorials of negative numbers, and we can use the pattern to show why:
You can't divide a number by 0, therefore -1! doesn't exist, so -2! doesn't exist and so on. So you can't do the factorial of any negative number.
(Or at least there no real solutions to negative factorials)
