If ‘+’ means ‘+’, ‘–’ means ‘×’ and ‘×’ means ‘–’, then what is the value of 100 × 20 + 10 + 12 + 2 – 3?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 108
Replace the signs (‘×’ and ‘–’ change places, ‘+’ stays), then work it out by BODMAS.
With the real signs: 100 – 20 + 10 + 12 + 2 × 3
\(2\times3=6\)
\(100-20+10+12+6=108\)
