Question
If x stands for ‘addition’, ÷ stands for ‘subtraction’, + stands for ‘multiplication’, and – stands for ‘division’, then 80 x 54 – 6 + 3 ÷ 9 = ?
Solution
The equation after sign change can be rewritten as:  80 + 54 ÷ 6 x 3 – 9 = ? 80 + 9 x 3 – 9 = ? 80 + 27 – 9 = ? 80 + 18 = ? ? = 98  Hence, the correct answer is (B).
