It's far from clear what *anything* multiplied by itself zero times should be. A better way of thinking about what x**n for integer n means is this: Start with 1, and multiply it by x n times. The result of this is clearly 1 when n is 0, regardless of the value of x. > 5**4 = 5*5*5*5 = 625 No: 5**4 = 1*5*5*5*5 5**3 = 1*5*5*5 5**2 = 1*5*5 5**1 = 1*5 5**0 = 1 -- Greg
