Question

alguém me ajuda POR FAVOR

1) 2 + 8 – 3 – 5 + 15 =
2) 12 + [35 - (10 + 2) +2] =
3) [(18 + 3 · 2) ÷ 8 + 5 · 3] ÷ 6 =
4) 37 + [-25 – (-11 + 19 – 4)] =
5) 60 ÷ {2 · [-7 + 18 ÷ (-3 + 12)]} =
6) -8 + {-5 + [(8 – 12) + (13 + 12)] – 10} =
7) 3² – {2 + (11 – 15) – [5 + (-3 + 1)] + 8} =
8) [-1 + (2² – 5 · 6)] ÷ (-5 + 2) + 1 =
9) [ – (2³ – 8) · 2 – 24] ÷ [2 ² – (3 + 2)] =
10) {[(8 · 4 + 3) ÷ 7 + (3 + 15 ÷ 5) · 3] · 2 – (19 – 7) ÷ 6} =
