Question

Explain briefly about the various types of cryptarithms.

Answer 1

An alphametic cryptarithm is where the digits in the expression are replaced with letters. The first modern alphametic is attributed to Henry Dudeney where SEND+MORE=MONEY has the solution 9567+1085=10652. A digimetic cryptarithm is where the numerical digits are replaced with other numerical digits. Skeletal division cryptarithms are arguably the most complex and are where a long division problem is set up but all or some of the numbers are replaced with symbols, such as asterisks.
