Question

(-13).(57-34)+57(13-45)

Answer 1

( -13 ) . ( 57 - 34 ) + 57 ( 13 - 45 )

= ( -13 ) . 23 + 57 . ( -32 )

= ( -299 ) + ( -1824 )

= -2123

Answer 2

(-13) x ( 57 - 34 ) + 57 x ( 13 - 45 )

= -13 x 57 - ( -13 ) x 34 + 57 x 13 - 57 x 45

= ( -13 x 57 + 57 x 13 ) + 13 x 34 - 57 x 45

= 0 +  442 - 2565

= 2123

Answer 3

( -13 ) x ( 57 - 34 ) + 57 x ( 13 - 45 )

= ( -13 ) x 23 + 57 x ( -32 )

= ( -299 ) + ( -1824 ) 

= -2123
