Michael Swenson of Goodyear, Ariz., sent a well-reasoned response to the puzzle presented in our last newsletter. Michael observes that if A is a constant and O is a constant, and if A does not equal O, then A will never = O. Therefore, he concludes, either A is a variable, or O is a variable, or both are variables.
