frozenrose_885 May 12, 2007	Good Job! Very interesting. I love making equations...that I know my classmates probably wouldn't be able to solve.
javaguru Jan 20, 2009	Not much of a teaser, nor much of a math problem. Obfuscation does not make a teaser. Just following the problem meant I already had the answer when I finished reading the question.
