Answer 1

Resposta:

b) +5 – 6 + 10 – 3 – 5 + 7 – 2 + 8 – 4 + 2 – 1

R: + 32 - 21 = 11

c) +10 – 3 – 2 – 7 + 2 + 6 + 4 – 7 – 2 + 12 – 1

R: + 34 - 22 = 12

d) – 5 – 7 – 2 + 10 + 2 – 5 + 3 + 4 – 7 + 5 + 2 – 10

R: - 36 + 26 = - 10

e) + 10 – 2 – 8 + 1 + 3 – 7 – 8 + 10 + 1 – 9 – 2 – 3

f) – 10 + 4 – 8 + 3 + 5 – 4 – 7 + 2 + 3 – 5 + 4

R: - 34 + 21 = - 13

g) + 2 – 7 – 5 – 3 – 5 + 4 – 8 + 20 – 4 – 2 + 3 + 7

R: + 36 - 34 = 2

h) +8 – 5 + 3 – 1 – 5 + 6 + 7 – 10 + 2 – 7 + 3 – 7 + 5

I) – 6 – 4 – 7 + 3 + 10 + 2 – 1 – 3 + 10 – 6 – 4 + 2

R: - 31 + 27 = - 4

J) – 9 + 2 + 3 – 7 + 1 + 2 – 8 – 3 + 10 – 6 + 3 – 4 – 1 + 5

k) + 2 – 7 + 3 + 8 – 9 + 2 – 1 + 7 – 6 – 8 + 20 – 12 – 3 + 5
