[698+875]+125
=698+[875+125]
=698+1000
=1698
698+(875+125)=698+1000=1698

(698+875)+125=698+(875+125)=698+1000=1698
( 698 + 875 ) + 125
= 698 + 875 + 125
= 698 + ( 875 + 125 )
= 698 + 1000
= 1698
(698+875)+125
=698+(875+125)
=698+1000
=1698
( 698 + 875 ) + 125
= 698 + ( 875 + 125 )
= 698 + 1000
= 1689
