Solve:
THINK*NOT=ARMAMENTS ,
then try to restore the (not so clever) text below, coded by simple substitution:
7811$ 721$ , 7211$ 78 ; 6384 51$
50 5298 7$ 705381 3078 .
rem1: You can go top down or bottom up.
rem2: Analytical approach preferred.
Going bottom up, the message is
"MERRY MARY, MARRY ME; THEN TRY TO TAKE MY MOTHER HOME."
Or at least it would be, if 6384 in the not so clever text were 5384. That's correction 1.
THINKOARME is
53649 02178
Then THINK*NOT = 53649*405 = 21727845 = ARMAMENT
(Not ARMAMENTS).
The Alphametic in the problem as given is impossible in base 10, as it has 11 different characters. But it all works out if the S is removed.
