- Single-Digit Addition
- Result
- 24
How the clues would have read
- Today's equation begins with a single-digit number.
- This puzzle uses addition only.
- The result is a 2-digit even number.
The numbers behind it
- Divisibility: 6 is divisible by 2 and 3, 9 is divisible by 3, 9 is divisible by 3, and 24 is divisible by 2, 3, 4, 6, 8, and 12
- Digital roots: 6 → 6, 9 → 9, 9 → 9, 24 → 2+4 = 6
- Prime factorization: 6 = 2×3, 9 = 3², 9 = 3², 24 = 2³×3
Why the structure matters
This puzzle's shape is A+B+C=DE — a single-digit 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 single-digit addition, most of the search space is gone before you have spent a single guess.
The result, 24, factors as 2³×3 — those factors are exactly the operations that could have produced it.
