Difficulty: Medium
Correct Answer: 46 - 6 + 4 x 5 ÷ 3 = 71
Explanation:
Introduction / Context:
Here each printed sign represents a different arithmetic operation. We must translate consistently, then compute both sides to identify the true statement.
Given Data / Assumptions:
Concept / Approach:
Translate each option into real operations, simplify the left-hand side (LHS), and compare to the right-hand side (RHS).
Step-by-Step Solution:
(B) 46 − 6 + 4 x 5 ÷ 3 → 46 * 6 ÷ 4 + 5 − 3 after mapping? No—translate carefully:
“−” → ×, “+” → ÷, “x” → +, “÷” → −.
LHS(B): 46 × 6 ÷ 4 + 5 − 3 = (276 ÷ 4) + 5 − 3 = 69 + 5 − 3 = 71, which matches RHS 71.
Check (A), (C), (D): their translated LHS values do not equal the stated RHS constants.
Verification / Alternative check:
Re-run the translation and arithmetic to confirm only (B) balances to 71.
Why Other Options Are Wrong:
After translation their LHS evaluate to different numbers than the RHS, so the equalities fail.
Common Pitfalls:
Mistranslating one of the symbols or applying left-to-right evaluation instead of operator precedence.
Final Answer:
46 - 6 + 4 x 5 ÷ 3 = 71
