### BAD::September 2012 Basic Arithmetic Dates

 These BADs need to be checked for correctness. ```summation(9,12)=42; summation(sqrt(9),12)=75; summation(sqrt(9)!,12)=63 ```
```09/01/12: 1*summation(9,12)=42 ["Answer to Life, the Universe, and Everything"]
09/02/12: sqrt(9)!*2=12
09/03/12: 9+3=12
09/04/12: 12/4=sqrt(9) ... sqrt(9)!*sqrt(4)=12
