  1. 1) |31-17| – |13-52|
    =|14| – |-39|
    = 14 – 39
    =-25
    2) -|5| + (-19) + 18+|11-4|-57
    = -5-19 + 18 + |7| – 57
    =-24 + 18 + 7 – 57
    =-56
    3) 126 + (-20)+|124| – (-320)-|-150|
    = 126 -20 + 124 + 320 – 150
    = (126+124)+(-20+320)-150
    = 250+300 -150
    = 550-150
    = 400
    4) (-17)+5+8+17+(-3)
    = [(-17)+17] + (5+8-3)
    = 0 + (13-3)
    =0+10
    =10

  2. Giải đápLời giải và giải thích chi tiết:
     1) |31-17|-|13-52|
    =|14|-|-39|
    =14-39
    =-25
    2) -|-5|+(-19)+18+|11-4|-57
    =-5-19+18+|7|-57
    =-6+7-57
    =-56
    3) 126+(-20)+|124|-(-320)-|-150|
    =126-20+124+320-150
    =106+444-150
    =400
    4) (-17)+5+8+17+(-3)
    =(-17+17)+(5+8-3)
    =0+(5+5)
    =10
