b) – {-7 + [-6 + 15 – (-9 + 13 + 17) – (6 - 5)]}




c) - 9 -[15 – (7 - 8) - 6] – [9 – (6 - 3)]




d) – {14 – [9 – (6 - 17) - 3] – [-5 – (8 – 3 - 7)]}




e) – 19 – [-7 – (6 – 3 - 19)] – [-9 – 2 - 7]​

Answer 1

Respuesta:

A) - 5 - (-8) + {-9 - [-6 + (5 - 9)]-[9 -7 - 6]}

- 5+8+{-9-[-6+5-9]-[9-7-6]}

3+{-9+6-5+9-9+7+6}

3-9+6-5+7+6

-6+6-5+13

-5+13

+8

b) – {-7 + [-6 + 15 – (-9 + 13 + 17) – (6 - 5)]}

- {-7+[-6+15+9-13-17 - 6+5]}

- {-7-6+15+9-13-17-6+5}

+7+6-15-9+13+17+6-5

c) - 9 -[15 – (7 - 8) - 6] – [9 – (6 - 3)]

- 9-[15-7+8-6]-[9-6+3]

- 9-15+7-8+6-9+6-3

- 24-1-3+3

- 25

d) -{14- [9 -(6- 17)- 3]- [-5 -(8 - 3 -7)]}

-{14-[9-6+17-3]-[-5-8+3+7]}

-{14-9+6-17+3+5+8-3-7}

-14+9-6+17-3-5-8+3+7

-5-6+14-13+10

e) – 19 – [-7 – (6 – 3 - 19)] – [-9 – 2 - 7]

- 19-[-7-6+3+19]-[-9-2-7]

- 19+7+6-3-19+9+2+7

- 12+3-10+9

- 22+12

- 10
