Puzzle Guy Greg Pliska takes equal portions of words and numbers, mixes well, and whips up a quiz called “Initiarithmetic.” The idea is to guess the words based on the initial letters of well-known phrases involving numbers. For example: “There are 12 M in the Y.” Wait, that was too easy. How about this one: “There are 2 K of P in the W. T W D the W into T K of P, and T W D.” This is part of a complete episode.
