Answer 1

487 x 789 + 487 x 211

= 487 x ( 789 + 211 )

= 487 x 1000

= 487 000

456 + 324 + 456 + 1234

= 780 + 1690

= 2470 

4567 + 1278 + 1224

= 5845 + 1224

= 7069

Answer 2

=479899

Answer 3

487 × 789 + 487 × 211 

= 487 x ( 789 + 211 )

= 487 x 100

= 48700

456 + 324 + 456 + 1234 

= ( 456 + 324 ) + ( 456 + 1234 )

= 780 + 1690

= 2470

4567 + 1278 + 1224 

= 5845 + 1224

= 7069

Answer 4

487 × 789 + 487 × 211 = 487 × (789 + 211) = 487 × 1000 = 487000

456 + 324 + 456 + 1234 = 2470

4567 + 1278 + 1224 = 7069
