If ‘+’ means ‘×’, ‘–’ means ‘÷’, ‘×’ means ‘–’ and ‘÷’ means ‘+’, then what is the value of 16 ÷ 64 – 8 × 4 + 2?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 16
Replace every sign by the sign it stands for, all at once, then work it out by BODMAS.
‘÷’ becomes ‘+’, ‘–’ becomes ‘÷’, ‘×’ becomes ‘–’ and ‘+’ becomes ‘×’: 16 + 64 ÷ 8 – 4 × 2
\(64\div8=8\)
\(4\times2=8\)
\(16+8-8=16\)
