    -(-171 + 89 + 223 ) – ( 71 – 105 – 111 ) + 223
    = 171 – 89 – 223 – 71 + 105 + 111 + 223
    = ( 171 – 71 ) – 89 + ( 223 – 223 ) + 105 + 111
    = 100 – 89 + 0 + 105 + 111
    = 11 + 105 + 111
    = 116 + 111
    = 227

    Giải đáp:
     $-(-171+89+223)-(71-105-111)+223$
    $= 171-89-223-71+105+111+223$
    $= (171-71+111)+(223-223)+(105-89)$
    $= 211+0+16$
    $= 227$
