Answer 1

Resposta:

a) 18 : 2 – 5 x 6 – 4 = 6-30-4 = -28

b) 240 : 3 + 5 – 19 = 80+5-19 = 66

c)270 : 9 – 3 + (11 + 25 x 2) = 270:9-3+(11+50)= 270:9+61= 30+61= 91

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) – 6 : 2= 3+4–6 : 2= 3+4-3= 4

f)78 : 2 + (9 x 5) – 33 = 78 : 2 + 45 – 33 = 156+45 – 33= 168

g)2 x (7 – 4) – 12 : 3 + 25 = 2 x 3 – 12 : 3 + 25 = 6-4+25=27

h)15 + 3 x 7 – 2 x 3 + 8 : 2 =15 + 21 – 6 + 4= 36-10= 26
