- 25
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 odd number.
The numbers behind it
- Divisibility: 7 is prime, 3 is prime, 6 is divisible by 2 and 3, and 25 is divisible by 5
- Digital roots: 7 → 7, 3 → 3, 6 → 6, 25 → 2+5 = 7
- Prime factorization: 7 = 7, 3 = 3, 6 = 2×3, 25 = 5²
Why the structure matters
This puzzle's shape is A+B*C=DE — a mixed addition and multiplication, 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 addition and multiplication, most of the search space is gone before you have spent a single guess.
The result, 25, factors as 5² — those factors are exactly the operations that could have produced it.
