Show answer & explanation
Correct answer: D
Interchange the operators:
Original expression: 4 - 12 + 3 ÷ 12 × 6
Interchange '+' with '÷' and '×' with '-':
New expression: 4 × 12 ÷ 3 + 12 - 6
Apply BODMAS/PEMDAS:
Division: 12 ÷ 3 = 4
Multiplication: 4 × 4 = 16
Addition: 16 + 12 = 28
Subtraction: 28 - 6 = 22
Final Answer: Option 4
