Answer 2

         

⇒ 76 - 4 - [6 + {19 - (48 - 57 - 17)}]

⇒ 76 - 4 - [6 + {19 - 48 + 57 + 17}]

⇒ 76 - 4 - 6 - {19 - 48 + 57 + 17}

⇒ 76 - 4 - 6 - 19 + 48 - 57 - 17

⇒ 21

This is the actual method for such methods.

First we have to calculate those in the parentheses bracket, and then in the square bracket, and then in the braces. Also, you can do it by cancelling the brackets in this order.

First I cancelled the parentheses bracket, then the square bracket, and then the curly bracket. So I got the answer 21.

Thank you. :-))
