So we must have E = 5 and N = 6. This means D + E = 7 + 5 = 12, and thus Y = 2. So we have solved for all the letters! SEND + MORE = 9567 + 1085 = 10652.
What is the meaning of cryptarithm?
Cryptarithm, mathematical recreation in which the goal is to decipher an arithmetic problem in which letters have been substituted for numerical digits.
What is cryptarithmetic problem in AI?
Cryptarithmetic Problem is a type of constraint satisfaction problem where the game is about digits and its unique replacement either with alphabets or other symbols. In cryptarithmetic problem, the digits (0-9) get substituted by some possible alphabets or symbols.
How do you solve Cryptarithms problems?
There are key elements to solving most alphametics. In many cases the result of an addition problem is one digit longer (in digit-length) than the addends – the numbers added. If there are only two addends, this implies that the extra digit is the number 1.

How do you solve Cryptarithmetic problems?
Rules for Solving Cryptarithmetic Problems
- Each Letter, Symbol represents only one digit throughout the problem.
- Numbers must not begin with zero i.e. 0567 (wrong) , 567 (correct).
- Aim is to find the value of each letter in the Cryptarithmetic problems.
- There must be only one solution to the Cryptarithmetic problems.
How are alphametics used to spell out words?
Alphametics are cryptarithms that spell out words. Given a mathematical expression, every digit in the expression is replaced by a letter. One of the most famous alphametics, spelling out ‘SEND MORE MONEY’ appears above. This alphametic was first published by Henry Dudeney, a British puzzlist, in 1924. Five rules govern alphametics:
What do you need to know about an alphametic?
An alphametic is a peculiar type of mathematical puzzle, in which a set of words is written down in the form of an ordinary “long-hand” addition sum, and it is required that the letters of the alphabet be replaced with decimal digits so that the result is a valid arithmetic sum.
Is the problem of alphametics a solvable problem?
The problem of alphametic construction can essentially be thought of as a very difficult form of constrained writing: the object is to write a phrase or sentence that (a) reads well, and (b) when considered as an alphametic (with the last word being the sum word), it is solvable (preferably with a unique solution).
How long does it take to solve an alphametic?
The process of solving an alphametic is itself interesting, often illustrating the triumph of logic over trial and error. The puzzle above (SEND + MORE = MONEY) is especially elegant in this regard – it can be solved in a matter of seconds via a few observations.
