〖1/4算式〗
    作业：求算式 (0.1+0.2*(0.4-0.1)*2)*0.2*(3.3-0.5)*24 的值.
    题型：数学计算
    解:
          (0.1+0.2*(0.4-0.1)*2)*0.2*(3.3-0.5)*24
        =(0.1+0.2*0.3*2)*0.2*(3.3-0.5)*24
        =0.22*0.2*(3.3-0.5)*24
        =0.22*0.2*2.8*24
        =0.044*2.8*24
        =0.1232*24
        =2.9568
    答案:(0.1+0.2*(0.4-0.1)*2)*0.2*(3.3-0.5)*24=2.9568
〖2/4算式〗
    作业：求算式 (0.1+0.2*(0.4-0.1)*3)*0.2*(3.3-0.5)*24 的值.
    题型：数学计算
    解:
          (0.1+0.2*(0.4-0.1)*3)*0.2*(3.3-0.5)*24
        =(0.1+0.2*0.3*3)*0.2*(3.3-0.5)*24
        =0.28*0.2*(3.3-0.5)*24
        =0.28*0.2*2.8*24
        =0.056*2.8*24
        =0.1568*24
        =3.7632
    答案:(0.1+0.2*(0.4-0.1)*3)*0.2*(3.3-0.5)*24=3.7632
〖3/4算式〗
    作业：求算式 ((0.2+0.2*(0.4-0.1))*0.2+0.1*0.2*(0.4-0.1))*(3.1-0.5)*6 的值.
    题型：数学计算
    解:
          ((0.2+0.2*(0.4-0.1))*0.2+0.1*0.2*(0.4-0.1))*(3.1-0.5)*6
        =((0.2+0.2*0.3)*0.2+0.1*0.2*(0.4-0.1))*(3.1-0.5)*6
        =(0.26*0.2+0.1*0.2*(0.4-0.1))*(3.1-0.5)*6
        =(0.26*0.2+0.1*0.2*0.3)*(3.1-0.5)*6
        =0.058*(3.1-0.5)*6
        =0.058*2.6*6
        =0.1508*6
        =0.9048
    答案:((0.2+0.2*(0.4-0.1))*0.2+0.1*0.2*(0.4-0.1))*(3.1-0.5)*6=0.9048
〖4/4算式〗
    作业：求算式 ((0.2+0.2*(0.4-0.1)*2)*0.2+0.1*0.2*(0.4-0.1))*(3.1-0.5)*12 的值.
    题型：数学计算
    解:
          ((0.2+0.2*(0.4-0.1)*2)*0.2+0.1*0.2*(0.4-0.1))*(3.1-0.5)*12
        =((0.2+0.2*0.3*2)*0.2+0.1*0.2*(0.4-0.1))*(3.1-0.5)*12
        =(0.32*0.2+0.1*0.2*(0.4-0.1))*(3.1-0.5)*12
        =(0.32*0.2+0.1*0.2*0.3)*(3.1-0.5)*12
        =0.07*(3.1-0.5)*12
        =0.07*2.6*12
        =0.182*12
        =2.184
    答案:((0.2+0.2*(0.4-0.1)*2)*0.2+0.1*0.2*(0.4-0.1))*(3.1-0.5)*12=2.184
