Resposta:

a) -4; b) -7; c) 17; d) -11; e) -23; f) 0; g) 0; h) 12

Explicação passo a passo:

a) +1 -3 -2 = +1 -5 = -4

b) -4 -5 -8 +10 = -17 +10 = -7

c) -7 +20-15+20-1 = -23 +40 = 17

d) 8-10-7+13-14+5-6 = -37+26 = -11

e) -13+7-9+5-13 = -35+12 = -23

f) -20+10-10+20+14-13-1 = -44+44 = 0;

g) -8-10-17-3+4-7+8-1 = -29+29 = 0;

h) +6-7-13-26+54-2 = 60-48 = 12
