Question

(-31).52+(-26).(-162)

Answer 1

( - 31 ) . 52 + ( - 26 ) . ( - 162 )

= ( - 31 ) . 52 + 26 . 162

= ( - 31 ) . 52 + 26 . 2 . 81

= ( - 31 ) . 52 + 52 . 81

= 52 . [ ( - 31 ) + 81 ]

= 52 . 50

= 2600

Answer 2

(-31) x 52 + (-26)x ( -162)

=(-31) x (-2) x (-26) + (- 26) x (-162)

= 62 x (-26) + ( - 26) x ( - 162)

=( -26)x [62 + (- 162)

=( - 26) x ( -100)

= 2600
