Game where digits are replaced by letters or other symbols in an arithmetic operation.

In a cryptarithm, a single symbol (letter or other symbol) replaces a single digit.

If the different elements form a meaning, then the cryptarithm is called an alphametic.

### Example

Replace the letters with digits so that the numbers found produce an accurate addition:

\(\space\)
SIX
+ SEVEN
+ SEVEN TWENTY |
Solution :
650
+ 68782 + 68782 138214 |

The solution to the alphametic TEN+ TEN+ FORTY = SIXTY is 850 + 850 + 29 786 = 31 486.
