If L denotes ‘÷’, M denotes ‘×’, P denotes ‘+’ and Q denotes ‘–’, then what is the value of 9 P 9 L 9 Q 9 M 9?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → –71
Replace each letter by its sign, then work it out by BODMAS (division and multiplication before addition and subtraction).
With the signs: 9 + 9 ÷ 9 – 9 × 9
\(9\div9=1\)
\(9\times9=81\)
\(9+1-81=-71\)
