Do you know everything about Factorials?

When I was in 7th grade at Amity Junior High School in Orange Connecticut, I gave a presentation on Factorial numbers.


Here’s some interesting code:



FOR i = 1 TO 80




PROCEDURE Factorial(n)

      IF n=1

            RETURN n


RETURN n*Factorial(n-1)



What do the base of natural logs (exp(1) = 2.718281828…), PI (3.14159…) and the square root of 2 have to do with Factorial ?


(In case you were wondering, I did not include the transcendental math in my 7th grade presentation)


I don’t know everything about the fascinating Factorials!

    Gee, and I thought my presentation on "The Fascinating Facets of Nine" (showing all the cool properties of the number 9 and its multiples) was cool in the 7th grade science fair at Carey School in San Mateo, CA (

    Thanks for the interesting math tidbit. I read more about Stirling’s Approximation at‘s%20approximation

  2. Eeeeeepppp!!! Transendental mathmatics. Everyone run for your lives!!!
