Hi.
  Consider please this Erlang code:
   
  code: 
    
---------------------------------
  
  

fac(1) ->
  1;
fac(N) ->
  N * fac(N - 1).

  
---------------------------------
    
I don't understand whats happening when I call:
fac(5)
I'm not sure but it seems to me it is "Recursion", right?
5 * fac(4)
4 * fac(3)
3 * fac(2)
etc.. 
  Thanks.
