Cryptarithmetic is a type of mathematical game consisting of a mathematical equation among unknown numbers, whose digits are represented by letters. The goal is to identify the value of each letter. In this video we learn tips and tricks to solve these verbal arithmetic problems.
Cryptarithmetic is the science and art of creating and solving cryptarithms.
A cryptarithm is a genre of mathematical puzzle in which the digits are replaced by letters of the alphabet or other symbols.
The invention of Cryptarithmetic has been ascribed to ancient China. This art was originally known as letter arithmetic or verbal arithmetic. In India, during the Middle Ages, were developed the arithmetical restorations or “skeletons” a type of cryptarithms in which most or all of the digits have been replaced by asterisks.
The word cryptarithmetic (“cryptarithmie” in French) was introduced by M. Vatriquant, writing under the pseudonym Minos, in the May 1931 issue of Sphinx, a Belgian magazine of recreational mathematics published in French from 1931 to 1939.
A type of alphametic addition puzzle termed “doubly-true” was introduced in 1945 by Alan Wayne. It is made up of “number words” that, when read, also form a valid sum.
