Question

-35+{7+[-12-18+2-1).-16}

Answer 1

-35+{7+[-12-18+2-1]-16}
-35+{7+[-30+2-1]-16}
-35+{7+[-28-1]-16}
-35+{7+[-29]-16}
-35+{7-29-16}
-35+{-22-16}
-35+{-38}
-35-38=-73

Answer 2

= - 35 + {7 + [ - 12 -18 + 2 - 1)] - 16}

= - 35 + {7 + [ - 30 + 1] - 16}

= - 35 + { 7 + [ - 29] - 16}

= - 35 + { 7 - 29 - 16}

= - 35 + { 7 - 45}

= - 35 + { - 38}

= - 35 - 38

= - 73
