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 Each digit has been replaced by a letter.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 cryptarithms, such as the famous

    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, and hit "Calculate" to see if substituting a different digit for each letter makes it a valid addition 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.
