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.

re: HELP !! I think I found out the SMALLEST Number by Bryan)
Yes Bryan I went through those two comments "let's not reinvent the wheel" and Charlie's reply to that post but I still do not understand why you asked me to check those comments. Is there anything wrong with my answer ? That is: sin [2^{-(31!)}], and if yes then what is it ? Please do let me know.
