Cryptarithm Uniqueness 9A73Ad
1. The problem is to determine if the cryptarithm SEND + MORE = MONEY has only one solution.
2. Cryptarithms like SEND + MORE = MONEY are designed so that each letter represents a unique digit and the sum holds true.
3. The solution found previously is:
$$S=9, E=5, N=6, D=7, M=1, O=0, R=8, Y=2$$
4. Due to the constraints (unique digits, leading digits not zero, and the sum structure), this cryptarithm has a unique solution.
5. This uniqueness is a known fact in classic cryptarithm puzzles; no other digit assignments satisfy the equation.
Final answer: There is only one solution to the cryptarithm SEND + MORE = MONEY, which is the one given above.
