132 × 11 + 8 – 3 ÷ 12 = -16 From option 1) by interchanging signs - and ×, we get LHS = 132 - 11 + 8 × 3 ÷ 12 = 134 – 11 = 123 ≠ RHS From option 2) by interchanging signs + and -, we get LHS = 132 × 11 - 8 + 3 ÷ 12 ≠ RHS From option 3) by interchanging signs + and ×, we get LHS = 132 + 11 × 8 – 3 ÷ 12 ≠ RHS From option 4) by interchanging signs × and ÷, we get LHS = 132 ÷ 11 + 8 – 3 × 12 = 12 + 8 – 36 = -16 = RHS |
