Cryptarithms

Cryptarithms are mathematical problems involving addition, subtraction, multiplication, or division. The digits are replaced by letters of the alphabet or some other symbols. 

 

Rules:

1. Two or more letters may not represent the same digit.

2.  Numbers must not start with a zero.

3. The solution is unique (unless otherwise stated).
