Check out this fun blog post by math wizard Ben Orlin, who calculates the total number of gifts in “The 12 Days of Christmas.” In the words of Mr Orlin, “The song invited a lot of questions, but one in particular leapt out to the mathematical mind …: How many gifts, in all, did my true love give to me?” (Tip of our hat to fellow math lover Cliff Pickover.)
