About Cryptarithms

The ability to sum numbers and perform logical reasoning are the only skills required for solving cryptarithms. Nevertheless, these puzzles are often witty and challenging to solve.

A cryptarithm is a mathematical puzzle where digits in an arithmetic equality are replaced by letters. It is defined so that distinct letters correspond to distinct digits. Moreover, when the letters are converted back by the original digits, the resulting equality must be valid. The problem is to find the original digits.

90 сryptarithms with their translations to 6 languages are presented.

Enjoy!
