(111 + 222 + 333 + 444 + 555 + 666 + 777 + 888 + 999)x 2.................999 x 2 x 2 x 2 ?
A.(111 + 222 + 333 + 444 + 555 + 666 + 777 + 888 + 999)x 2 > 999 x 2 x 2 x 2 = 9990 > 7992
B.(111 + 222 + 333 + 444 + 555 + 666 + 777 + 888 + 999)x 2 < 999 x 2 x 2 x 2 = 9990 < 7992
C.(111 + 222 + 333 + 444 + 555 + 666 + 777 + 888 + 999)x 2 = 999 x 2 x 2 x 2 = 9990 = 7992

111 + 222 + 333 + 444 x 0 + 111 + 222
= ( 111 + 222 ) + ( 111 + 222 ) + ( 333 + 444 x 0 )
= 333 + 333 + 333
= 333 x 3
= 999
111 +222+333+444 * 0 +111+222 = ?
111 + 222 + 333 + 0 + 111 + 222
= 999 nha
