Dr MATHS with Steve Humble Cryptarithmetic or Alphametic puzzles are mathematical problems in which each digit is replaced by a letter.
In the 20th century Alphametic puzzles became very popular, appearing in a range of newspapers and magazines.
Like all good Alphametic puzzles, the letters make words that form a meaningful phrase.

In an alphametic, letters are substituted for numbers in an arithmetic problem, and the reader is invited to find the solution.
A special case of narrative alphametics are doubly-true alphametics, in which the narrative consists of a correct arithmetical statement, such as THREE + FOUR = SEVEN, with the solution 28566 + 7495 = 36061.
The following narrative alphametics have unique solutions and are soluble by hand without excessive enumeration (although in some cases they may require quite a bit of analysis).
An alphametic, as most Word Ways readers are surely aware, is a puzzle like SEND + MORE = MONEY, in which letters are to be replaced with decimal digits to make a valid addition sum.
There are four types of two-addend alphametic, with the words having N, N, and N letters, or N, N, N+1, or N, N+1, N+1, or N, N+1, N+2.
