b) ( 140 + 20 – 10 ) – 63 – ( 18 – 10 – 8 ) =
c) 135 – 35 + ( 13 – 8 + 4 ) – 7 + 20 =
d) 500 + 36 – ( 8 + 12 – 6 ) + 21 – ( 80 + 123) =

Answer 1

a) 60 – ( 14 – 4 + 6 ) – 16 – 6 = 22

b) ( 140 + 20 – 10 ) – 63 – ( 18 – 10 – 8 ) = 87

c) 135 – 35 + ( 13 – 8 + 4 ) – 7 + 20 = 122

d) 500 + 36 – ( 8 + 12 – 6 ) + 21 – ( 80 + 123) = 340
