Answer 1

`a)997xx4+997xx6=997xx(4+6)=997xx10=9970`

`b)458xx19+458xx27=458xx(19+27)=458xx46=21068`

`c)1863xx85-55xx1863=1863xx(85-55)=1863xx30=55890`

`d)618xx134+618xx256=618xx(134+256)=618xx390=241020`

Answer 2

`997 xx 4 + 997 xx6`

` = 997 xx ( 4 + 6)`

` = 997 xx 10`

` = 9970` 

________________________

` 458 xx19 + 458 xx 27`

` = 458 xx ( 19 + 27)`

` = 458 xx 46`

` = 21068`

________________________

` 1863 xx 85 - 55 xx 1863`

` = 1863 xx (85 - 55)`

` =1863 xx 30`

` = 55890`

________________________

`618 xx 134 + 618 xx 256`

` = 618 xx ( 134 + 256)`

` = 618 xx 390`

` = 241020`

Answer 3

`997xx4+997xx6`

`=997xx(6+4)`

`=997xx10`

`=9970`

`458xx19+458xx27`

`=458xx(19+27)`

`=458xx46`

`=2748`

`1863xx85-55xx1863`

`=1863xx(85-55)`

`=1863xx20`

`=37260`

`618xx134+618xx256`

`=618xx(134+256)`

`=618xx390`

`=241020`
