36 x 28 + 4 x 9 x 82 + 64 x 69 + 8 x 41 x 8
= 36 x 28 + ( 4 x 9 ) x 82 + 64 x 69 + ( 8 x 8 ) x 41
= 36 x 28 + 36 x 82 + 64 x 69 + 64 x 41
= 36 x ( 28 + 82 ) + 64 x ( 69 + 41 )
= 36 x 110 + 64 x 110
= 110 x ( 36 + 64 )
= 110 x 100
= 11000

=36.28+(4.9).82+64.69+(8.8).41
=36.28+36.82+64.69+64.41
=36.(28+82)+64.(69+41)
36.101+64.101
=(36+64).101=100.101=10100.
