Now try some other possibilities for yourself! A cryptarithm is a mathematical puzzle where the digits in a sum have been replaced by letters. In each of the puzzles below, each letter stands for a different digit. Bearing in mind that none of the numbers below have 0 as a leading digit, can you find a solution to all of these cryptharithms?
What do the letters stand for in a cryptarithm?
A cryptarithm is a mathematical puzzle where the digits in a sum have been replaced by letters. In each of the puzzles below, each letter stands for a different digit.
How are four dominoes used in a cryptarithm?
Use these four dominoes to make a square that has the same number of dots on each side. A cryptarithm is a mathematical puzzle where the digits in a sum have been replaced by letters. In each of the puzzles below, each letter stands for a different digit.
Which is a rare variation of a cryptarithm?
Reverse cryptarithm A rare variation where a formula is written and the solution is the corresponding cryptarithm whose solution is the formula given.
How is the Goldbach conjecture a mathematical problem?
The Goldbach conjecture is the claim that every double integer greater than 2 can be written as the sum of two prime numbers. It is one of the biggest mathematical problems that cannot be proved. In the original Goldbach hypothesis, Goldbach claims that every integer greater than 2 can be written as the sum of 3 prime numbers.
Which is an example of an alphametic cryptarithm?
Alphametic A type of cryptarithm in which a set of words is written down in the form of a long addition sum or some other mathematical problem. The object is to replace the letters of the alphabet with decimal digits to make a valid arithmetic sum.
Where did the term cryptarithm get its name?
The name “cryptarithm” was coined by puzzlist Minos (pseudonym of Simon Vatriquant) in the May 1931 issue of Sphinx, a Belgian magazine of recreational mathematics, and was translated as “cryptarithmetic” by Maurice Kraitchik in 1942.
