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 re: solution by arbor)

While that is true, we can usually assume that base 10 is meant when nothing to the contrary is specified.
