〖1/4算式〗
    作业：求算式 ((304+741)*(1+0.222*2+0.466*3+0.032*6*2+0.288+0.165+0.18*2)+311) 的值.
    题型：数学计算
    解:
          ((304+741)*(1+0.222*2+0.466*3+0.032*6*2+0.288+0.165+0.18*2)+311)
        =(1045*(1+0.222*2+0.466*3+0.032*6*2+0.288+0.165+0.18*2)+311)
        =(1045*4.039+311)
        =4531.755
    答案:((304+741)*(1+0.222*2+0.466*3+0.032*6*2+0.288+0.165+0.18*2)+311)=4531.755
〖2/4算式〗
    作业：求算式 ((304+620)*(1+0.222*2+0.466*3+0.138+0.288+0.18*2)+311) 的值.
    题型：数学计算
    解:
          ((304+620)*(1+0.222*2+0.466*3+0.138+0.288+0.18*2)+311)
        =(924*(1+0.222*2+0.466*3+0.138+0.288+0.18*2)+311)
        =(924*3.628+311)
        =3663.272
    答案:((304+620)*(1+0.222*2+0.466*3+0.138+0.288+0.18*2)+311)=3663.272
〖3/4算式〗
