9*8/36=2
Structure
A*B/CD=E
Type
Mixed Multiplication and Division
Result
2

How the clues would have read

  • Today's equation begins with a single-digit number.
  • This puzzle uses division and multiplication operations.
  • The result is a single-digit even number.

The numbers behind it

  • Divisibility: 9 is divisible by 3, 8 is divisible by 2 and 4, 36 is divisible by 2, 3, 4, 6, 9, 12, and 18, and 2 is prime
  • Digital roots: 9 → 9, 8 → 8, 36 → 3+6 = 9, 2 → 2
  • Prime factorization: 9 = 3², 8 = 2³, 36 = 2²×3², 2 = 2

Why the structure matters

This puzzle's shape is A*B/CD=E — a mixed multiplication and division, 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 division, most of the search space is gone before you have spent a single guess.

The result, 2, is prime — so it cannot be reached by multiplying two smaller whole numbers, which rules out a whole family of candidate equations immediately.
