435 x 25  + 76 x 435 - 435

Answer 1

`435xx25+76xx435-435`

`= 435xx(25+76-1)`

`= 435xx100`

`= 43500`

Answer 2

\(435\times25+76\times435-435\\ =435\times\left(25+76-1\right)\\ =435\times100\\ =43500\)

Answer 3

435 x 25 + 76 x 435 - 435

= 435 x 25 + 76 x 435 - 435 x 1

= 435 x (25 + 76 - 1)

= 435 x 100 

= 43500

Answer 4

435 x 25 + 76 x 435 - 435 x 1

= 435 x ( 25 + 76 - 1 )

= 435 x          100

=          43 500
