By using standard arithmetic rules, we need to decipher the alphabet. What Is Cryptarithmetic? Cryptarithmetic is the science and art of creating and solving cryptarithms. A Cryptarithmetic 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developed the arithmetical restorations or “skeletons” a type of cryptarithms in which most or all of the digits have been replaced by asterisks.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 world’s best known alphabetic puzzle is undoubtedly SEND + MORE = MONEY. It was created by H. E. Dudeney and first published in the July 1924 issue of Strand Magazine associated with the story of a kidnapper’s ransom demand.

Questions are only based on basic mathematics like, find the value of A+B+C, or 2A+C or triangle related questions. Each alphabet takes only one number from 0 to 9 uniquely. Two single digit numbers sum can be maximum 19 with carryover. So, carry over in problems of two number addition is always 1. Try to solve left most digit in the given problem. If a × b = kb, then the following are the possibilities (3 × 5 = 15; 7 × 5 = 35; 9 × 5 = 45) or (2 × 6 = 12; 4 × 6 = 24; 8 × 6 = 48) EXAMPLE PROBLEM 1. The following questions are based on the following multiplication, where each digit has been replaced by an alphabet.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
