Answer 3

77-11.(30 + 7 )

= 77- 330 - 77

= 77 - 77 - 330

= 0 - 330

= -330 

85.( 35 - 27 ) - 35.( 85 - 27 )

= 2975 - 2295 - 2975 + 945

= 2975 - 2975 -2295 + 945

= 0 - 2295 + 945

= -1350

Answer 4

1) 85 . ( 35 - 27 ) - 35 . ( 85 - 27 )

= 85 . 35 - 85 . 27 - 35 . 85 + 35 . 27

= ( 85 . 35 - 35 . 85 ) - 27 . ( 85 - 35 )

= 0 - 27 . 50

= 0 - 1350

= -1350

2) 77 - 11 . ( 30 + 7 )

= 77 - 11 . 37

= 77 - 407

= -330
