bueno las otras no me deja subir
JERARQUÍA DE LAS OPERACIONES:
a) 5-[7-2×(1-9)÷4+12÷6]+4×(-2)
5-[7-2×(-8) ÷ 4 + 2] - 8
5 - [7 + 16 ÷ 4 + 2] - 8
5 - [7 + 4 + 2] - 8
5 - 13 - 8 => -16
b) 1-(-9÷3+8÷2)-[4-(6-12÷6)×3]
1 - (-3 + 4) - [4 - (6 - 2) × 3]
1 - (1) - [4 - (4) × 3]
1 - 1 - [4 - 12]
1 - 1 - [- 8]
1 - 1 + 8 => 8
c) 6-(-9+18÷3)-[3÷(-15÷3+6)-11]
6 - (-9 + 6) - [3 ÷ (- 5 + 6) - 11]
6 - (- 3) - [3 ÷ (1) - 1]
6 + 3 - [3 - 1]
9 - 2 => 7
d) [-2+(2-5)÷3] - [(14÷7+2)-2×(3-4)]
[- 2 + 3 ÷ 3] - [(2 + 2) - 2 × (- 1)]
[- 2 + 1] - [4 + 2]
- 1 - 6 => -7
