Cryptarithms - Number Puzzles

Cryptarithms
Cryptarithms are a type of mathematical puzzle in which the digits are replaced by symbols (typically letters of the alphabet). For example:

9567 + 1085 = 10652

can be represented like this:

abcd + efgb = efcbh

 

Alphametics
The term alphametic is used when the letters form words and phrases. Here's a famous one:

SEND
+MORE
MONEY
Solve

There is also a subset of alphametics called 'doubly-true' where the words are spelt out numbers which also form a valid sum:

FORTY
TEN
+TEN
SIXTY
Solve

Try these other examples.

 

Cryptarithm Rules

  • Each letter represents a unique digit.
  • Numbers must not start with a zero.
  • The solution is unique (unless otherwise stated).
