An odd number of odd numbers cannot add to 30.
Only an even number of odd numbers can.
Odd+Odd=Even <--- First two odd numbers added
Odd+Odd=Even <--- Next two odd numbers added
Even+Even=Even <---- First four odd numbers added together
Odd+Even=Odd <---- Last odd number add to the first four total
