111 + 222 - 222 - 111
= 333 - 222 - 111
= 111 - 111
= 0
nha bn
111+222-222-111
=333-222-111
=111-111
=0
ủng hộ mik nhé
Bằng 0 bạn nhé ! Bạn k cho mình nhaaaaaaaaaaaaaaaaaaaaaaa ! Thank you
111 + 222 - 222 - 111
= 333 - 222 - 111
= 111 x 3 - 111 x 2 - 111 x 1
= 111 x ( 3 - 2 - 1 )
= 111 x 0
= 0
k mình nha 
\(111+222-222-111\)
\(=333-222-111\)
\(=333-\left(222+111\right)\)
\(=333-333\)
\(=0\)
111 + 222 - 222 - 111
= 333 - 222 - 111
= 111 x 3 - 111 x 2 - 111 x 1
= 111 x ( 3 - 2 - 1 )
= 111 x 0
= 0
111 + 222 - 222 - 111
= 333 - 222 - 111
= 111 x 3 - 111 x 2 - 111 x 1
= 111 x ( 3 - 2 - 1 )
= 111 x 0
= 0
