Question
Respected Sir,
      Assalamoalekum,
          Sir my question is:
"What is the value of zero fictorial? and if the answer is 1 then how?"
 "The answer of 1/0 = infinity. Is there any proof of this."
  Please explain the both of the question and if possible with examples.
         Thanks in advance.
                  Allah Hafiz,
                     Faithfully yours,
                         Zahoor Ahmed.

Answer
0! does equal 1.  It comes from a gamma function in higher mathematics.  Even more interesting is the fact that
(1/2)! is equal to [(pi)^1/2]/2 or 0.886
If you divide 1 by smaller and smaller numbers, the answer becomes larger and larger, going toward infinity.
