You can use the digits 1,2,and 3 once only and any mathematical symbols you are aware of, but no symbol is to be used more than once. The challenge is to see if you can make the smallest positive number.
Special rules: You cannot use Euler's number or pi or infinity.
Special thanks to: Rhonda Wendel for Make the most of these digits and for the problem text which was slightly altered.
(In reply to re(2): This is my Guess...(factorials of fractions).....
Well I think you need to check your calculations Charlie. Since we know that 1/9 = .11, 1/99 = .01...., and so on. So as the denominator keeps on increasing, the numerator always remaining fixed and equal to 1, we see that the value of the fraction gradually approaches 0(ZERO), then how can you say that 1 divided by (9261)! will give you a result which is close to 1(One) and not to 0(ZERO). So could you please perform the calculations again Charlie.
