    Lời giải và giải thích chi tiết:
    126+(-20)+124
    =106+124=230
    3^5-10^2:5^2+2^3.7
    =243-100:25+8.7
    =295
    (134-34).(-28)+72.[(-55)-45]
    =100.(-28)-72.100
    =100.(-28-72)=100.(-100)=-10000
    (-25)+5+(-8)-(-25)+(-13)
    =-25+5-8+25-13=-16
    60+40.[225-(17-2)^2]}
    =60+40.0=60
    (143.43-99.43-43^2):43
    =43 (143 – 99 – 43): 43
    =43.1 : 43
    =43 : 43
    =1
