    作业：求算式 9*(7.61+2*0.3+1.28)*2.47+(48+3)*(2.25+2*0.3+1.785)*2.47+2*3*(7.61+1-0.083)*0.888 的值.
    题型：数学计算
    解:
          9*(7.61+2*0.3+1.28)*2.47+(48+3)*(2.25+2*0.3+1.785)*2.47+2*3*(7.61+1-0.083)*0.888
        =9*9.49*2.47+(48+3)*(2.25+2*0.3+1.785)*2.47+2*3*(7.61+1-0.083)*0.888
        =9*9.49*2.47+51*(2.25+2*0.3+1.785)*2.47+2*3*(7.61+1-0.083)*0.888
        =9*9.49*2.47+51*4.635*2.47+2*3*(7.61+1-0.083)*0.888
        =9*9.49*2.47+51*4.635*2.47+2*3*8.527*0.888
        =85.41*2.47+51*4.635*2.47+2*3*8.527*0.888
        =210.9627+51*4.635*2.47+2*3*8.527*0.888
        =210.9627+236.385*2.47+2*3*8.527*0.888
        =210.9627+583.87095+2*3*8.527*0.888
        =210.9627+583.87095+6*8.527*0.888
        =210.9627+583.87095+51.162*0.888
        =210.9627+583.87095+45.431856
        =794.83365+45.431856
        =840.265506
    答案:9*(7.61+2*0.3+1.28)*2.47+(48+3)*(2.25+2*0.3+1.785)*2.47+2*3*(7.61+1-0.083)*0.888=840.265506
