Martin Gardner dies at age 95 Message #1 Posted by Don Shepherd on 24 May 2010, 5:36 a.m.
His obituary.
Another one of the great ones passes. He revealed the fascinating side of mathematics to generations of readers through his books, articles, and Scientific American columns. He will be missed. Who will take his place? The guy who writes the comic strip Foxtrot has a mathematical leaning, but I doubt that a worthy successor to Mr. Gardner is likely, unfortunately.
In honor of his passing, I propose an easy challenge for a programmable calculator. Identify the only number(s) such that the sum of the digits times the product of the digits equals the original number.
And, no, 95 is not one of them: (9+5) * (9*5) =/= 95.
