In Letterland there are no numerals. They use the decimal system of counting just like we do but the digits 0-9 are represented by the first ten letters of the alphabet A-J inclusive but in no particular order. The following calculations are typical:

(1) A + G = C

(2) B x J = FH

(3) GE x AI = HDB

What number is represented by ABCDEFGHIJ?
