e) 3 + (16 – 4 x 3) – 6 : 2 =

f) 78 : 2 + (9 x 5) – 33 =

g) 2 x (7 – 4) – 12 : 3 + 25 =

h) 15 + 3 x 7 – 2 x 3 + 8 : 2 =

Answer 1

Resposta:

a) 18 : 2 - 5 x 6 – 4 =

9-30-4= -25

b) 240 : 3 + 5 – 19 =

80-14=66

c) 270 : 9 – 3 + (11 + 25 x 2) =

30-3+11+50=88

d) (640 – 50 x 8) : 6 – 32 =

(640-400):6-32=

240:6-32=40-32=8

e) 3 + (16 – 4 x 3) – 6 : 2 =

3+16-12-3= 4

f) 78 : 2 + (9 x 5) – 33 =

39+40-33=46

g) 2 x (7 – 4) – 12 : 3 + 25 =

2x3-4+25=6+21=27

h) 15 + 3 x 7 – 2 x 3 + 8 : 2 =

15+21-6+4=34
