Answer:

Here's your answer mate :)

Step-by-step explanation:

{(71 + 21) - (-30 + 20)}

= 71 + 21 -(-30) -(+20)

= 71 + 21 + 30 - 20...{minus is multiplied by the bracket so minus multiplied by minus is plus so, +30 and minus multiplied by plus is minus so, -20}

= 92 + 30 - 20

= 122 - 20

= 102
