Answer 1

Resposta:Segue as contas abaixo na explicação

Explicação passo-a-passo:

a) ( + 6 ) + ( - 1 ) + ( - 5 ) + ( - 3 )--->+6-1-5-3--->+6-9--->-3

b) ( - 5 ) – ( - 2 ) – ( - 3 ) – ( - 1 )--->-5+2+3+1--->-5+6--->+1

c) ( - 8 ) – ( + 2 ) – ( - 1 ) + ( - 6 )--->-8-2+1-6--->-16+1--->-15

d) ( + 7 ) – ( - 3 ) + ( - 4 ) + ( - 5 )--->+7+3-4-5-->+10-9--->+1

e) ( - 5 ) – ( - 2 ) + ( + 4 ) – ( + 8 ) + ( + 1 )--->-5+2+4-8+1--->-13+7--->-6

f) 10 + ( - 7 ) + ( + 2 ) – ( + 4 ) – ( - 1 ) + ( - 3 )-->10-7+2-4+1--->+13-11--->+2

g) 15 – 2 – 6 – ( + 3 ) – ( - 1 )--->15-2-6-3+1--->+16-11-->+5

h) 20 – ( - 5 ) – 12 – 1 – ( - 3 )--->20+5-12-1+3--->+28-13-->+15

i ) 18 – ( - 18 ) + 7 – ( - 7 ) + 0 – 4 =18+18+7+7+0-4--->+50-4--->+46

j) – 21 – 6 – 7 – ( - 15 ) – 2 – ( - 10 )--->-21-6-7+15-2+10--->-36+25-->-11
