    题型：数学计算
    解:
          34.83*16.22+8.37*14.69+269.86*12.09+1557.04*4.39-(121.05*16.78+405.69*10.78+99.28*5.74+1243.57*2.25)
        =34.83*16.22+8.37*14.69+269.86*12.09+1557.04*4.39-9772.4569
        =564.9426+8.37*14.69+269.86*12.09+1557.04*4.39-9772.4569
        =564.9426+122.9553+269.86*12.09+1557.04*4.39-9772.4569
        =564.9426+122.9553+3262.6074+1557.04*4.39-9772.4569
        =564.9426+122.9553+3262.6074+6835.4056-9772.4569
        =687.8979+3262.6074+6835.4056-9772.4569
        =3950.5053+6835.4056-9772.4569
        =10785.9109-9772.4569
        =1013.454
    答案:34.83*16.22+8.37*14.69+269.86*12.09+1557.04*4.39-(121.05*16.78+405.69*10.78+99.28*5.74+1243.57*2.25)=1013.454
