a) 209-7 -56

202-56=146

b) (590+10) -6x8

600-6x8

600-48 = 552

c) 1000-( 235 +10 -81)

1000- 164= 836

209 - 35:5 - 7×8 =

209 - 7 - 56 =

202 - 56 = 146

( 590 + 100:10 ) - 6×8 =

( 590 + 10 ) - 48 =

600 - 48 = 552

1000 - ( 235 + 40:4 - 9×9 ) =

1000 - ( 235 + 10 - 81 ) =

1000 - ( 245 - 81 ) =

1000 - 164 = 836
