〖1/3算式〗
    作业：求算式 ((251+620)*(1+13.8%+9.3%+46.6%+11.1%+4.7%)+311) 的值.
    题型：数学计算
    解:
          ((251+620)*(1+13.8%+9.3%+46.6%+11.1%+4.7%)+311)
        =(871*(1+13.8%+9.3%+46.6%+11.1%+4.7%)+311)
        =(871*1.855+311)
        =1926.705
    答案:((251+620)*(1+13.8%+9.3%+46.6%+11.1%+4.7%)+311)=1926.705
〖2/3算式〗
    作业：求算式 ((251+620)*(1+13.8%+9.3%+46.6%+11.1%+4.7%)+311)*(1+130.1%)*(1+46.6%)*(1+20%+320*0.12%)*((90+100)/(90+100+100+88))*(1+5%) 的值.
