Recursion wierdness?

Question

Already having some trouble with a factorial recursion but noticed this bit- where I try to print something and the output is not what I expected? Is it something to do with printing within a recursion function and calling local variables? It looks sort of right but the numbers only make sense in each loop going down one line.

Answer 1

Your recursion works correctly:
9! = 362880
But your code prints wrong values because you forgot to put parenthesis around num-1 in line#9 (multiplication has higher precendence than addtion). It sholud be:
print(num,'x',num-1,"=",num * (num-1))
it will print the product of the current and the next numbers

Answer 2

What is your expected output?
9! => 362880 only..
Edit:
Oh.. It should be num*(num-1), instead of num*num-1

Answer 3

Haha probably wasn't a good idea to work on it at 4am :) so it was operator precidence it looks like from typo
