The value of 9 factorial plus 6 factorial is 363,600
0!=1! 1=1 The factorial of 0 is 1, not 0
yes. (0!+0!+0!+0!+0!)! where ! refers the factorial of the number
A recursive formula for the factorial is n! = n(n - 1)!. Rearranging gives (n - 1)! = n!/n, Substituting 'n - 1' as 0 -- i.e. n = 1 -- then 0! = 1!/1, which is 1/1 = 1.
You first look at the number that is before the !(factorial sign). Then you times all positive integers (which means it doesn't include 0), including the number itself. The answer is the factorial of the original number beside the ! sign. EX.:4!=1x2x3x4=24
