Questions tagged [cryptarithm]

A cryptarithm is a numeric puzzle in which a mathematical equation is given where the digits are replaced by letters, the object being to recover the original equation. The canonical example is SEND + MORE = MONEY, which has the unique solution 9567 + 1085 = 10652. There are variants, such as long division problems where most of the digits are replaced by asterisks.
