18 + 6 – 6 ÷ 3 × 3 = 6 is to be true. We need to check with the options. From option 1, by interchanging signs + and x, we get 18 x 6 - 6 ÷ 3 + 3 = 109 - LHS LHS is not equal to RHS. From option 2, by interchanging signs + and ÷, we get: 18 ÷ 6 – 6 + 3 × 3 = 3 – 6 + 9 = 6 = RHS Hence, Option 2 is correct We dont need to check further options. |
