Class 7Integer Expressions with BracketsIntegers
  • A20 + 8 − 5 + 3
  • B20 − 8 − 5 + 3
  • C20 − 8 − 5 − 3
  • D20 − 8 + 5 − 3

Step-by-Step Solution

A minus before the bracket flips every sign inside: +8 → −8, −5 → +5, +3 → −3. So 20 − 8 + 5 − 3 = 14. Check: 8 − 5 + 3 = 6 and 20 − 6 = 14.
Answer: D) 20 − 8 + 5 − 3
