8*7+8=64
- Structure
- A*B+C=DE
- Type
- Mixed Multiplication and Addition
- Result
- 64
How the clues would have read
- Today's equation begins with a single-digit number.
- This puzzle uses addition and multiplication operations.
- The result is a 2-digit even number.
The numbers behind it
- Divisibility: 8 is divisible by 2 and 4, 7 is prime, 8 is divisible by 2 and 4, and 64 is divisible by 2, 4, 8, 16, and 32
- Digital roots: 8 → 8, 7 → 7, 8 → 8, 64 → 6+4 = 10 → 1
- Prime factorization: 8 = 2³, 7 = 7, 8 = 2³, 64 = 2⁶
Why the structure matters
This puzzle's shape is A*B+C=DE — a mixed multiplication and addition, where each letter stands for one digit. Recognising the shape before the arithmetic is what separates a three-guess solve from a six-guess struggle: once you know the equation is a mixed multiplication and addition, most of the search space is gone before you have spent a single guess.
The result, 64, factors as 2⁶ — those factors are exactly the operations that could have produced it.
