Option 2: + and × After replacement the equation becomes; = 25 × 5 + 7 - 12 ÷ 3 = 128 is not equal to 26. Hence, option 2 is not the correct answer. |
|
Option 3: - and ÷ After replacement the equation becomes; = 25 + 5 × 7 ÷ 12 - 3 = 24.91 is not equal to 26. Hence, option 3 is not the correct answer. |
|
Option 4: + and - After replacement the equation becomes; = 25 - 5 × 7 + 12 ÷ 3 = -6 is not equal to 26. Hence, option 4 is not the correct answer. |
