consider any standard monthly calendar with the weeks arranged in rows, for instance, March 2008. Take any four dates in a month on each calendar that appear in a 2-by-2 array, and take the difference of the diagonal products. or instance March 3, march 4, march 10 and march 11 form a 2 by 2 array, and the difference of the diagonal products is 3(11)-4(10). considering the set of all possible months that occur on a calendar for all years, what set of dates will produce the greatest difference of products? Explain your answer?
