alguem responde essas pra min????
CALCULE: a) 74+{96-[51-(60-20)]}=
b) 99+{10+[63-(26-13)]}=
c) 40+[15+(12-7)+3]-9=
d) {87-[38+(13-5)+4]-12}-3=
e) {[(90-40)-20]+12}=
f) 28+{[37-(17-9)+(10-6)]-5}=
g) 98+{37-[(17+(10-7)+7)]}=
h) 2 + 8 – 3 – 5 + 15 =
i) 12 + [35 - (10 + 2) +2] =
j) [(18 + 3 · 2) ÷ 8 + 5 · 3] ÷ 6 =
k) 37 + [-25 – (-11 + 19 – 4)] =
l) 60 ÷ {2 · [-7 + 18 ÷ (-3 + 12)]} – [7 · (-3) – 18 ÷ (-2) + 1] =
m) -8 + {-5 + [(8 – 12) + (13 + 12)] – 10} =
n) 3 – {2 + (11 – 15) – [5 + (-3 + 1)] + 8} =
