ayudaaaaa pliss para a horita con el procedimiento

Answer 1

Respuesta:

5-[5-(-8)-9]+4

5-4+4=5

B-  

-(-3+6+1)-[4-(6-3+1)-2]

(3+6+1)-[4-4-2]

10-(-2)

10+2= 12

C-

6-(-9+7-1)-[3-(-5-4+6)-1]

6+(9+7-1)-[3+(5-4+6)-1]

6+10-[3+7-1]

6+10-9=7

D-

28-[21-(12-3)-7]

28-[21-9-7]

28-5=23

E-

[-2+3.(2-5):3]-[(3-5+2)-2.(3-4)]

[1.(-3):3]-[0-2.(-1)]

[-3:3]-[-2.(-1)]

-1-2=  -3

F-

8-[6-(-3+7)-6]+4

8-[6+(3+7)-6]+4

8-[6+10-6]+4

8-10+4= 2
