### BAD::April 2013 Basic Arithmetic Dates

 These BADs need to be checked for correctness. ```summation(4,13)=85; summation(sqrt(4),13)=90 ```
```04/01/13: 13%4=1
04/02/13
04/03/13: 4*13+3=55  [MathBabbler's age on this date]
04/04/13
04/05/13: cuberoot(13-5)=sqrt(4)
04/06/13
04/07/13
04/08/13
04/09/13
04/10/13
04/11/13: 13-11=sqrt(4) ... 13+11=4!

04/26/13: 26/13=sqrt(4)
04/27/13: sqrt(4)+27+13=42 ["Answer to Life, the Universe, and Everything"]
04/28/13: 28%13=sqrt(4)
04/29/13: sqrt(4)+29=reverse_digits(13)  [13 & 31 are reversible primes]
