Answer
264

The correct answer is 264 — Combine the results to get 264.

Step-by-step solution

  1. Start with the units column: 3 - 9 cannot be done, so borrow 1 from the tens.
  2. Tens digit 1 becomes 0 and units become 13.
  3. Subtract units: 13 - 9 = 4.
  4. Now subtract the tens column: 0 - 4 cannot be done, so borrow 1 from the hundreds.
  5. Hundreds digit 5 becomes 4 and tens become 10.
  6. Subtract tens: 10 - 4 = 6.
  7. Subtract the hundreds column: 4 - 2 = 2.
  8. Combine the results to get 264.
Common mistake: Neglecting to borrow from the hundreds column

Concept tested: Subtraction with borrowing across hundreds
