Question

17 (-18+25)-18(-17+25)

 

Answer 1

\(17\left(-18+25\right)-18\left(-17+25\right)=-25\)

Answer 2

17 (-18+25)-18(-17+25)

=17.(-18)+17.25-18.(-17)+25.18

=[17.(-18)-18.(-17)]-(18.25-25.17)

=          0             - [25.(18-17)]

=          0             - (25.1)

=          0             -  25

= -25

Answer 3

17 x ( -18 + 25 ) - 18 x ( -17 + 25 ) = -25

Answer 4

17(-18+25)-18(-17+25)

=17.(-18)+17.25-18.(-17)+18.25

=[17.(-18)-18.(-17)]+(17.25-18.25)

=0+(17-18).25

=0+(-1).25

=0+(-25)

=-25
