    作业：求算式 (108*1.2*1.1*1.2+4)*11.25*1.15*1.15*30/100-(103*1.2*1.1*1.2+4)*11.25*1.15*1.15*30/100 的值.
    题型：数学计算
    解:
          (108*1.2*1.1*1.2+4)*11.25*1.15*1.15*30/100-(103*1.2*1.1*1.2+4)*11.25*1.15*1.15*30/100
        =175.072*11.25*1.15*1.15*30/100-(103*1.2*1.1*1.2+4)*11.25*1.15*1.15*30/100
        =175.072*11.25*1.15*1.15*30/100-167.152*11.25*1.15*1.15*30/100
        =1969.56*1.15*1.15*30/100-167.152*11.25*1.15*1.15*30/100
        =2264.994*1.15*30/100-167.152*11.25*1.15*1.15*30/100
        =2604.7431*30/100-167.152*11.25*1.15*1.15*30/100
        =78142.293/100-167.152*11.25*1.15*1.15*30/100
        =781.42293-167.152*11.25*1.15*1.15*30/100
        =781.42293-1880.46*1.15*1.15*30/100
        =781.42293-2162.529*1.15*30/100
        =781.42293-2486.90835*30/100
        =781.42293-74607.2505/100
        =781.42293-746.072505
        =35.350425
    答案:(108*1.2*1.1*1.2+4)*11.25*1.15*1.15*30/100-(103*1.2*1.1*1.2+4)*11.25*1.15*1.15*30/100=35.350425
