Using only the digits 0-9, but not 3 or 5, solve for each letter:
GRAPE - PLUM = APPLE
You can only use one digit for each letter.
I got the same solution:
GRAPE=94872
PLUM=7160
APPLE=87712
For some reason I was having a tough time with it until I turned it over and tried to solve APPLE+PLUM=GRAPE. Is that cheating?
