2/19/2012 -- Junior Circle: Cryptarithms. (Dr. Oleg Gleizer)

Cryptarithmetic, also know as cryptarithm, alphametics, or word addition, is a math game of figuring out unknown numbers represented by words. Different letters correspond to different digits. Same letters correspond to same digits. The first digit of a number cannot be zero. Deciphering cryptarithms is a great way to further familiarize ourselves with our numeral system (decimal place-value).
