A hoary old talk, solved with pencil before electricity was a thing.
Since the M in Money is the result of carry in base 10 of two single digits it is a 1 (we exclude 0 here though that would work, but then MONEY would be spelled ONEY).
In addition, the S plus 1 then needs to result in a carry, so S is 8 or 9, depending on whether there is a carry into that column. Onw can continue, but from here the computer is likely quicker.
<syntaxhighlight lang="julia">let
m = 1
for s in 8:9
for e in 0:9
e in [m, s] && continue
for n in 0:9
n in [m, s, e] && continue
for d in 0:9
d in [m, s, e, n] && continue
for o in 0:9
o in [m, s, e, n, d] && continue
for r in 0:9
r in [m, s, e, n, d, o] && continue
for y in 0:9
y in [m, s, e, n, d, o] && continue
if 1000s + 100e + 10n + d + 1000m + 100o + 10r + e ==
10000m + 1000o + 100n + 10e + y
