112 x 56 + 112 x 46 - 112 x 2

 

Answer 1

112(56+46-2)=112 x 100 = 11200

Answer 2

112 x 56 + 112 x 46 - 112 x 2

122 x ( 56 + 46 - 2 )

122 x 100

12200

Answer 3

= 112 x ( 56 + 46 - 2 )

= 11200

Answer 4

`112 xx 56 + 112 xx 46 - 112 xx 2`

`= 112 xx ( 56 + 46 - 2 )`

`= 112 xx 100`

`= 11200`

Answer 5

`112 xx 56 + 112 xx 46 - 112 xx 2`

`122 xx ( 56 + 46 - 2 )`

`122 xx 100`

`12200`
