    #Hà gửi ạ
    $1$+ $2$ – $3$ – $4$ + $5$ + $6$ – $7$ – $8$ +…+ $994$ – $995$ – $996$ + $997$+ $998$
    = $1$ + $2$ + $5$ – $3$ – $4$ + $6$ + $9$ – $7$ – $8$ +…. + $994$ + $997$ – $995$ – $996$ + $998$
    = $1$ + $0$ + $0$ +…. + $0$ + $998$
    = $1$ + $998$
    = $999$
    Vậy đáp án là $999$
