  1. – ( – 800 ) + ( 1267 – 987 ) – 67 + 1987
    = ( 1267 – 67 ) + ( 1987 – 987 ) + 800
    = 1200 + 1000 + 800
    = 2000 + 1000
    = 3000

  2. Giải đáp $*$ Lời giải và giải thích chi tiết:
     -(-800) +(1267 -987) -67 +1987
    =800 +1267 -987 -67 +1987
    =800+(1267-67)+(1987-987)
    =800+1200 +1000
    =2000+1000
    =3000
