Difficulty: Medium
Correct Answer: x - ÷
Explanation:
Introduction / Context:
Here, we must create an expression equal to zero by selecting a specific sequence of three operators. Because × and ÷ dominate precedence, structuring the middle subtraction to balance two multiplicative terms is a common path to zero.
Given Data / Assumptions:
Concept / Approach:
Try to form A − B where A and B are equal. Choosing 'x - ÷' yields 8 × 6 − 96 ÷ 2, which is promising because 8 × 6 = 48 and 96 ÷ 2 = 48, giving 48 − 48 = 0.
Step-by-Step Solution:
Select 'x - ÷': 8 × 6 − 96 ÷ 2.Compute: 8 × 6 = 48; 96 ÷ 2 = 48.Difference: 48 − 48 = 0.Therefore the equation holds.
Verification / Alternative check:
Check one alternative: 'x ÷ -' ⇒ 8 × 6 ÷ 96 − 2 = 48 ÷ 96 − 2 = 0.5 − 2 ≠ 0.
Why Other Options Are Wrong:
Common Pitfalls:
Evaluating strictly left-to-right and ignoring precedence; you must compute × and ÷ before the subtraction to see the intended cancellation.
Final Answer:
x - ÷
