Compute (9 - 3²) × 9.

Explanation:
Understanding order of operations is what this tests. Exponents are evaluated before subtraction, and expressions inside parentheses are evaluated before multiplying. Compute 3^2 to get 9, then inside the parentheses do 9 - 9 = 0. Multiply by 9 to get 0. So the result is 0.
