Answer 1

Explicação passo-a-passo:

a) 3 - 2 - 5= 3 -7= - 4

b) - 2 - 1 - 5= -8

c) 4 - 2 - 3 = 4 - 5= -1

d) 5+3 +1= +9

e) 4 -6 -7 +6 +7= +17 - 13= +4

f) - 3 +5 -6 +8 +4= - 9 + 17= +8

g) +(+5) - ( +5) + (-1)= 5-5-1= -1

h) - (-4) - (-7+4) - 6 - ( -1)=

+4 - ( -3) - 6 +1=

4 +3 -6 +1=

+8 -6=

+2

i) 18 - ( -10) +20 - ( +2) - ( -9+3)=
