alguém pode me ajudar pfvrrrr????​

Answer 1

Resposta:

a)30+[-16-(-7+10)]

  30+[-16+3]

   30-13=17

b)-10-[11+(-10-6)+1]

  -10-[11-16+1]

   -10-3=-13

c)18-(14+15)-[13-(16-21)]

  18-29-[13-5]

   18-29-8=19

d)-5+(2-4)-(7-1)

  -5-2-6=13

e)-(-22)-[29+(27-23-26)-28]

  22-[29+22-18]

  22-33=11

f)(-5+3)-(5-9)+(8-1)-11

 -2-4+7-11=-10

g)9-(-10)-[-21-(13-13+25)]-(-18)

  9+10-[-21-25]+18

  9+10+47+18=77

h)11+[-17-(-22+16)+(-29)]-(-46+54)

  11+[-17+6-29]-7

  11-40-7=58
