〖1/1算式〗
    作业：求算式 (120.8+(181-120.8)/(8000-5000)×(8705.142218×70%-5000))×1×0.85×1×60%-45.792094-17 的值.
    题型：数学计算
    解:
          (120.8+(181-120.8)/(8000-5000)×(8705.142218×70%-5000))×1×0.85×1×60%-45.792094-17
        =(120.8+60.2/(8000-5000)×(8705.142218×70%-5000))×1×0.85×1×60%-45.792094-17
        =(120.8+60.2/3000×(8705.142218×70%-5000))×1×0.85×1×60%-45.792094-17
        =(120.8+60.2/3000×1093.599553)×1×0.85×1×60%-45.792094-17
        =142.745262×1×0.85×1×60%-45.792094-17
        =142.745262×1×0.85×1×0.6-45.792094-17
        =142.745262×0.85×1×0.6-45.792094-17
        =121.333473×1×0.6-45.792094-17
        =121.333473×0.6-45.792094-17
        =72.800084-45.792094-17
        =27.00799-17
        =10.00799
    答案:(120.8+(181-120.8)/(8000-5000)×(8705.142218×70%-5000))×1×0.85×1×60%-45.792094-17=10.00799
