Question

What are the various types of cryptarithm?
 (with examples and detailed explanation)

Answer 1

Cryptarithm is nothing but verbal mathematics. It is nothing but a game or a puzzle which involves addition of words. The types of cryptarithm are generally alphametic, the digimetic, and the skeletal division. 
Alphametic 
a set of words is written down in the form of a long addition sum or some other mathematical problem. 

Digimetic 
digits are used to represent other digits. 

Skeletal division 
A long division in which most or all of the digits are replaced by symbols (usually asterisks) to form a cryptarithm.
