Difficulty: Medium
Correct Answer: 18 + 6 - 4 x 2 ÷ 3 = 26
Explanation:
Introduction / Context:
Each operator in the printed equation stands for a different actual operation. Determine which full equation remains true once all symbols are remapped and then evaluated with standard precedence.
Given Data / Assumptions:
Mapping: + → ×, − → ÷, × → +, ÷ → −.
Concept / Approach:
Remap an option and evaluate carefully. If LHS equals RHS, that option is correct.
Step-by-Step Solution (Option B):
Verification / Alternative check:
Checking the other options shows mismatches (e.g., Option A maps to 21, not 22).
Why Other Options Are Wrong:
After mapping, their left sides do not equal the right sides.
Common Pitfalls:
Final Answer:
18 + 6 - 4 x 2 ÷ 3 = 26
