Young Griswold uses something he just learned
in elementary school math class to solve a minor stumper. (Be
warned: the problem has a minor bug. Change "mix" to "nix".)

Published in the January 1986 issue of Ellery Queen Magazine.
(See also 1 to 999 and Ten, two other Griswold stories. Each of these "stories" is really more of a puzzle whose solution is found through some nonmathematical aspects of mathematical notation. A third Griswold story, Getting the Combination is noticeably more mathematical.)
