PFVR ME AJUDEM!!!!!​

Answer 1

Resposta:

a) 96 - (48 - 18 +20)

96 - (30 + 20)=

96 - 50=

46

b) 200 - (40 - 8 + 150)

200 - (32 + 150)=

200-182=

18

c) 80 +2 - (74 + 20 - 40)

80+2-(94-40)=

80+2-54=

82-54=

28

d) (80 - 40 + 25) - (100 - 60+ 15)

(40+25)-(40+15)=

65-55=

10

e) (80 - 75 + 3) + (70 + 54)

(5+3)+124=

8+124=

132

1) (8 x 2 - 10) +(18- 4 x 4)

(16-10)+(18-16)=

6+2=

8

g) 80: (2 x 4+2) - 7

80:(8+2)-7=

80:10-7=

8-7=

1

h) (20:10 +10: (5 x 2+2)

(2+10):(10+2)=

12:12=

1

i) 100 - {2 x [18 - (4 x 2 - 6)]}

100-{2x[18-(8-6)]}=

100- {2x[18-2]}=

100-{2x16}=

100-32=

68

j) 53 - 24 x 4

53-96=

43
