Yes you do: some programs have demonstrated that the permutation logic is not working ok, so feeding them 1234 is not the same as feeding 2134 or any other permutation.

Generating all 10,000 variation of the numbers combos will not in general help if you have logic errors in your script. As an example, generating all 10,000 will not help identify missing parenthesis or operator combos. I am not sure if it will help with the rounding or zero division problems either.

Code validation is a serious challange in this competition. Many of your tests & analysis have been very helpful in this regard.
