Which of the following is NOT correct?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 13 – 7 + 8 × 9 + 63 ÷ 9 = 88
Option 1 -
13 - 7 + 8 × 9 + 63/9 = 88
13 - 7 + 72 + 7 = 88
85 ≠ 88
Option 2 -
8 × 3 + 63/9 - 6 = 25
24 + 7 - 6 = 25
25 = 25
Option 3 -
42/6 + (2 × 5) × 1 + 9 = 26
7 + 10 + 9 = 26
26 = 26
Option 4 -
9 × 4 + (12 + 2) - 30 ÷ 3 = 40
36 + 14 - 10 = 40
40 = 40
Option one is correct.
