The correct answer is

12 and 13

The correct answer is 12 and 13.

Efficiency: While testing each option works, sometimes you can use logic. Look at how the position of the numbers affects the result (e.g., swapping numbers involved in multiplication or division might have a larger impact). Common Pitfalls: Errors often occur due to incorrect application of the order of operations or calculation mistakes when evaluating the new expression. Practicing such problems helps improve calculation speed and logical reasoning skills.
