Assume there are approximately 5,000,000,000 (5 billion) people on Earth living presently.

What would you estimate to be the result, if you multiply together the number of fingers on the left hand of every person actually alive today?
(For the purpose of this exercise, thumbs count as fingers.)

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

    Zero…!

    Because I know at least one person who is actually alive today AND has no fingers on his left hand (Number of fingers = 0). 

    Thus, 5 * 5 * 5 * …. * 5 * 0 * 5 * 5 * 5* 6 * 5 * …. * 5 = 0.  Hence the answer.
