35( 14-23) - 23 (14-35)=35.14-35.23-23.14+23.35

=(35.14-23.14)+(23.35-35.23)

=35.14-23.35-23.14+23.35

=(35.14-23.14)+(23.35-35.23)=

=14(35-23)+0

=14.12

=168

Ta có: 35(14-23)-23(14-35)
         =35.14-35.23-23.14-23.35
         =(35.14-23.14)-(35.23-23.35)
         = 14.(35-23)-0
         =14.12
         =168

ta tách: 35(14-23)-23(14-35)=35.14-35.23-23.14-23.35

=(35.14-23x14)-(35.23-23.35)

=14.(35-23)-0

=14.12

=168

Vậy kết quả =168

ket qua la 168

35(14-23)-23(14-35)

=35.14-35.23-23.14+23.35

=(23.35-35.23)+14(35-23)

=0+14.12

=168

35.(14-23)-23.(14-35)

= 35 . 14 - 35 . 23 - 23 . 14 + 23 . 35

= 35 . 14 - 23 . 14

= 14 . ( 35 - 23 )

= 14 . 12

= 168
