Options

Choose one · Correct answer highlighted

52 ÷ 4 + 5 × 8 − 2 = 36 Correct 43 × 7 ÷ 5 + 4 − 8 = 25 36 × 4 − 12 + 5 ÷ 3 = 420 36 − 12 × 6 ÷ 3 + 4 = 60

Applying operator interchange where minus means division, plus means subtraction, division means addition after correction makes left side 52+4-5*8/2 equals 36. Other equations fail under same mapping, confirming only first equation balances correctly to 36.
