[1/1 Formula]
    Work: Calculate the value of equation (20+18.0×0.7+19.4*3.4+19.2*0.8+19.8*4.1)*0.52-2*54*0.72 .
    Question type: Mathematical calculation
    Solution:
          (20+18.0×0.7+19.4*3.4+19.2*0.8+19.8*4.1)*0.52-2*54*0.72
        =195.1*0.52-2*54*0.72
        =101.452-2*54*0.72
        =101.452-108*0.72
        =101.452-77.76
        =23.692

    Answer:(20+18.0×0.7+19.4*3.4+19.2*0.8+19.8*4.1)*0.52-2*54*0.72=23.692
