I need to know when you have lettets how csn you deternine what the numbers will be. Ex: GRAPE - PLUM = APPLE. How would I he able to know what numhers represent the letters?

Thanks

GRAPE if E - M = E, M has to equal 0. GRAPE-PLU0=APPLE

- PLUM it is impossible for G - 0 = A. Therefore, A connote be 9
APPLE R cannote be 9. G cannot be 1.
Since you borrow, R is 4 and P is 7 G4A7E+7LU0=A77LE
try plugging G with 9 and A with 8 and U with 6
9487E+7L60=A77LE

Final solution:
G = 9
R = 4
A = 8
P = 7
E = 2
L = 1
U = 6
M = 0

GRAPE - PLUM = APPLE

94872 – 7160 = 87712
