Re: Math Problem
How is it determined that two of three ages must be the same at the start of the problem? Using your methodology should it not be d*e*f = 36 and d + e + f = X? How can you immediately eliminate one of the variables? In fact, at this point in the formulation of the problem, how is it known that there are not other sets of three factors whose product is 36 that add up to X?
