〖1/1算式〗
    作业：求算式 (218.6+(393.4-218.6)/(20000-10000)*(12734.4517-10000))×1×0.85×1×60%-45.792094-17-1 的值.
    题型：数学计算
    解:
          (218.6+(393.4-218.6)/(20000-10000)*(12734.4517-10000))×1×0.85×1×60%-45.792094-17-1
        =(218.6+174.8/(20000-10000)*(12734.4517-10000))×1×0.85×1×60%-45.792094-17-1
        =(218.6+174.8/10000*(12734.4517-10000))×1×0.85×1×60%-45.792094-17-1
        =(218.6+174.8/10000*2734.4517)×1×0.85×1×60%-45.792094-17-1
        =266.398216×1×0.85×1×60%-45.792094-17-1
        =266.398216×1×0.85×1×0.6-45.792094-17-1
        =266.398216×0.85×1×0.6-45.792094-17-1
        =226.438484×1×0.6-45.792094-17-1
        =226.438484×0.6-45.792094-17-1
        =135.86309-45.792094-17-1
        =90.070996-17-1
        =73.070996-1
        =72.070996
    答案:(218.6+(393.4-218.6)/(20000-10000)*(12734.4517-10000))×1×0.85×1×60%-45.792094-17-1=72.070996
