Question

15 – ( 3 – 2 ) + ( 7 – 4 ) =
25 – ( 8 – 5 + 3 ) – ( 12 – 5 – 8 ) =
( 10 – 2 ) – 3 + ( 8 + 7 – 5 ) =
( 9 – 4 + 2 ) – 1 + ( 9 + 5 – 3 ) =
18 – [ 2 + ( 7 – 3 – 8 ) – 10 ] =
– 4 + [ - 3 + ( - 5 + 9 – 2 ) ] =
– 6 – [ 10 + ( - 8 – 3 ) – 1 ] =
– 8 – [ - 2 – ( - 12 ) + 3 ] =
25 – { - 2 + [ 6 + ( - 4 – 1 ) ] } =
17 – { 5 – 3 + [ 8 – ( - 1 – 3 ) + 5
