〖1/1算式〗
    作业：求算式 (0.00083×(29791-9261)-12×0.0025×(961-441)+144×0.0025×11+6.6)×(0.1/(1-(1+0.1)^-11)) 的值.
    题型：数学计算
    解:
          (0.00083×(29791-9261)-12×0.0025×(961-441)+144×0.0025×11+6.6)×(0.1/(1-(1+0.1)^-11))
        =(0.00083×20530-12×0.0025×(961-441)+144×0.0025×11+6.6)×(0.1/(1-(1+0.1)^-11))
        =(0.00083×20530-12×0.0025×520+144×0.0025×11+6.6)×(0.1/(1-(1+0.1)^-11))
        =11.9999×(0.1/(1-(1+0.1)^-11))
        =11.9999×(0.1/(1-1.1^-11))
        =11.9999×(0.1/0.649506)
        =11.9999×0.153963
        =1.847541
    答案:(0.00083×(29791-9261)-12×0.0025×(961-441)+144×0.0025×11+6.6)×(0.1/(1-(1+0.1)^-11))=1.847541
