I noticed the failure of my memory reconstruction unit when I came across a Google book reference to my problem in Stanley Rabinowitz and Mark Bowron's Index to Mathematical Problems, 1975-1979, page 258. Presumably to save space, ONE + ONE + ONE + ONE = FOUR + ONE = FIVE is how it is printed in there, but I assure you that is not how I posed the problem, nor is it how the Journal of Recreational Mathematics published it: http://chesswanks.com/pot/alphametic.png On Apr 19, 2013, at 7:41 PM, Fred lunnon <fred.lunnon@gmail.com> wrote:

I hate to kick a man when he's down Hans --- but shouldn't this have read
ONE + ONE + ONE + ONE + ONE = FOUR + ONE = FIVE ??
