I'd print it here, but it's hard to get a good square drawn on this. If you figure that one out, what about a 20 by 20? 100 by 100? N by N? The next one is from Bill Taggart. What two integers with non-zero digits can be multiplied together to get 1,000,000,000? These aren't too difficult, but to make things interesting, send your solutions to me and I'll post the solutions in a few days. Have fun!!! Mark Gilje stolaf!gilje
