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 solution by Charlie)

This is true if we expect the answer to be written as a base 10 number. However, the question is not complete in the sense it does not specify which base the result is expected to be in. E.g. if it is expected to be written as a base 5 number, it would be 5,000,000,001 digits.
