    Lời giải và giải thích chi tiết:
    4567 + (1234 – 4567) – 4
    = 4567 + 1234 – 4567 -4 
    = 4567 + ( 1234 – 4)
    = 4567 + 1230
    = 5797
    b) 2001 – (53 + 1579) – (-53)
    = 2001 – 53 – 1579 – 53
    = ( 2001 – 159 ) – 53
    = 1842 – 53
    = 1789
    c) 35 – 17 + (2017 – 35 + (-2017)
    d) 115 – (-85) + 53 – (-500 + 53)
    = 115 + 85 + 53 + 500 +  53
    = 200 + 500 + 53
    = 700 + 53
    = 753
