b)115x(36+62)-15x(62+36)

Answer 1

a)63x113+36x113+113

=113x(36+63+1)

=113x100

=11300

b)115x(36+62)-15x(62+36)

=115x98-15x98

=11270-1470

=9800

Answer 2

a,63.113+36.113+113

=63.113+36.113+113.1

=(63+36+1).113

=100.113

=11300

b,115.(36+62)-15.(62+36)

=115.98-15.98

=(115-15).98

=100.98

=9800

Answer 3

a) 63 x 113 + 36 x 113 + 113 x1

    ( 63 + 36 + 1 ) x 113

    100 x 113 = 11300

b) 115 x ( 36 + 62 ) - 15 x ( 62 + 36 )

    115 x 98 - 15 x 98

     ( 115 - 15 ) x 98

     100 x 98 = 9800
