                                                                                             2)0x0=0  (by multiplaying)

                                                                                              3) 0! = 1  ( How ? )

0! can be found using definition of nC0 which means choosing zero things out of n things which can be done by only 1 method (by not choosing any that is common sense) now nC0 = 1

this means n!/(n-0)!x0! =1

n!/n!x0! = 1

1/0! = 1

Hence 0! = 1

1=1.0!

0!=1

In The Formula of nCr = n!/r!×(n-r)! when r=0; then it becomes 0!= n!/0!×n! = n!/n! = 1. Hence, Proved.
