The Rub - 2013 Pilot 1-1 was released on:
USA: 10 October 2013
Successor of n=n+1
Predecessor of n=n-1
Sum=[n+1]+[n-1]
Plus 1 plus minus 1=
[1]+[-1]=0
[n][n]
=2n
Hope this helps
n! = n * (n-1) !
n!/n = n*(n-1)!/n //divid by n both sides
n!/n = (n-1)!
let n = 1
1!/1 = (1-1)!
1 = 0!
Hence proved that 0! = 1.
