  1. Giải đáp:
     
    Lời giải và giải thích chi tiết:
    ( -18 ) + ( -31 ) + 98 + 18 + ( -69 )
    = -18 – 31 + 98 + 18 – 69
    = (18 – 18) – (31 + 69) + 98
    = 0 – 100 + 98
    = -100 + 98
    = -2

  2. Answer
    (-18) + (-31) + 98 + 18 + (-69)
    = -18 – 31 + 98 + 18 – 69
    = (18 – 18) – (31 + 69) + 98
    = 0 – 100 + 98
    = -100 + 98
    = -2
