Cryptarithms or Alphametics | Home | Your Feedback | Cryptograms |

A **cryptarithm** (or **alphametic**) is an
encoded arithmetic problem. Each digit has been replaced
by a letter. The object is to determine the original numbers.

This applet solves simple addition and multiplication cryptarithms, such as this famous one created by Henry Dudeney in 1924:

S E N D 9 5 6 7 +M O R E+1 0 8 5= M O N E Y = 1 0 6 5 2

Enter three "words" in the three upper boxes, choose + for addition or * for multiplication, and hit "Calculate" to see if substituting a different digit for each letter makes it a valid problem.

To enter the problem shown above, you would put **send**
in the first box, **more** in the second box, and
**money** in the third box. Do not include any blanks
or any other characters.
