Assume there are approximately 5,000,000,000 people on earth. What would you estimate to be the result, if you multiply together the number of fingers on every person's left hands?

(If you cannot estimate the number, then try to guess how long the number would be.)

(In reply to Try this number by Brian Smith)

Brian is correct. Forget the "log" math. Any 2nd grader can do this. At least one person on earth will have zero fingers. Anything times zero is zero!
