The correct answer is

29

To solve the equation 232 - 245/35 = ? × 18, let's follow these steps:

  1. Calculate 232:
    23 × 23 = 529
  2. Calculate 245/35:
    Dividing 245 by 35, we get 245/35 = 7
  3. Substitute these values into the equation:
    529 - 7 = ? × 18
  4. Simplify the left side of the equation:
    529 - 7 = 522
  5. Set the simplified equation:
    522 = ? × 18
  6. Now, solve for ? by dividing both sides by 18:
    ? = 522/18
  7. Calculate 522/18:
    522/18 = 29

Therefore, the value of the unknown in the equation is 29. Hence, the correct answer is 29.
