| Type | multiple_choice | |
| Option | +, -, ÷, ×, =, -, + | incorrect |
| Option | -, +, ×, ÷, -, +, = | incorrect |
| Option | -, +, ÷, ×, -, +, = | correct |
| Option | -, +, ÷, ×, =, -, + | incorrect |
| Solution | Take option C, 36 – 14 + 63 ÷ 9 × 11 – (6 + 3) = 90 LHS = 36 – 14 + 63 ÷ 9 × 11 – (6 + 3) = 36 – 14 + 7 × 11 – 9 = 36 – 14 + 77 – 9 = 90 LHS = RHS Hence, Option C is correct. | |
