b) 200 – (40- 8 +150)=

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

d) ( 80- 40 + 25) – ( 100 – 60+15)=

e) ( 80 – 75 +3 ) + (70+54)=

f) ( 2 -10) + ( 18 – 4 x4) =

Answer 1

a)

96 - (48 - 18 + 20)

96 - 50

= 46

b)

200 - (40 - 8 + 150)

200 - 182

= 18

c)

80 + 2 - (74 + 20 - 40)

80 + 2 - 54

= 28

d)

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

65 - 55

= 10

e)

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

8 + 124

= 132

f)

(2 - 10) + (18 - 4 × 4)

(2 - 10) + (18 - 16)

- 8 + 2

= - 6
