456 x 200 - 456 x 100
= 456 x ( 200 - 100)
= 456 x 100
= 45 600

715 + 456 + 544 + 285
= (715 + 285) + (456 + 544)
= 1000 + 1000
= 2000

544 + 135 + 157 + 843 + 865 + 456 = ( 544 + 456 ) + ( 135 + 865 ) + ( 157 + 834 ) = 1000 + 1000 + 1000 = 3000
456 x 36 + 456 x 65 - 456
= 456 x 36 + 456 x 65 - 456 x 1
= 456 x ( 36 + 65 -1 )
= 456 x 100
= 45 600
thanks
