1. The question:
g r a p e
- p l u m
------------
a p p l e
------------
2. e - m = e => m = 0; p = u + l;
r /= 0 & r - p = p & g > a > p => p{6,7}

3. a - l = p; r + 10 = 2p; g > a > p
let p = 7 => a = 8, g = 9, r = 4, l = 1, and u = 6

Answer: g=9 a=8 p=7 u=6 r=4 l=1 m=0, and e can be 2, 3, or 5.

Similarly let p = 6, the answer would be:

g=8 a=7 p=6 u=5 r=2 l=1 m=0, and e can be 3, 4, or 9
