〖1/1算式〗
    作业：求算式 (0.00083×(8000-1000)-12×0.0025×(400-100)+144×0.0025×11+6.6)×(0.1/(1-(1+0.1)^-11)) 的值.
    题型：数学计算
    解:
          (0.00083×(8000-1000)-12×0.0025×(400-100)+144×0.0025×11+6.6)×(0.1/(1-(1+0.1)^-11))
        =(0.00083×7000-12×0.0025×(400-100)+144×0.0025×11+6.6)×(0.1/(1-(1+0.1)^-11))
        =(0.00083×7000-12×0.0025×300+144×0.0025×11+6.6)×(0.1/(1-(1+0.1)^-11))
        =7.37×(0.1/(1-(1+0.1)^-11))
        =7.37×(0.1/(1-1.1^-11))
        =7.37×(0.1/0.649506)
        =7.37×0.153963
        =1.134707
    答案:(0.00083×(8000-1000)-12×0.0025×(400-100)+144×0.0025×11+6.6)×(0.1/(1-(1+0.1)^-11))=1.134707
