Question

(100+23).23+(200-77).77+456=???

Answer 1

(100+23).23+(200-77).77+456

= 123.23+123.77+456

= 123.(23+77)+456

= 123.100+456

= 12300+456

= 123456

Answer 2

  (100 + 23 ).23 + (200 - 77 ).77 + 456 

= 123 . 23 + 123 . 77 +  456

= 123 (77 + 23 ) + 456

= 123 . 100 + 456 

= 12300 + 456

= 12756
