Answer 1

Resposta:

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)-3+8-3+8+5-6=  -12+21=  9

h)+3-1+6+4-1-6+3+2= +18-2= 16

i)18+5-2-3+20+6+8+1-8+3=  58-13= 48

j)-32-1-12+14+7+5-6-9+3-17=  -32-1-12-6-9-17+14+7+5+3=-48
