〖1/1算式〗
    作业：求算式 (3.4-0.1)+4.1*2+(216-0.1)*2+(4.2-0.1)*3+(4.2-1.8)+(3.5-0.1)+(3.5-0.9)+(4.2-0.1)*6 的值.
    题型：数学计算
    解:
          (3.4-0.1)+4.1*2+(216-0.1)*2+(4.2-0.1)*3+(4.2-1.8)+(3.5-0.1)+(3.5-0.9)+(4.2-0.1)*6
        =3.3+4.1*2+(216-0.1)*2+(4.2-0.1)*3+(4.2-1.8)+(3.5-0.1)+(3.5-0.9)+(4.2-0.1)*6
        =3.3+4.1*2+215.9*2+(4.2-0.1)*3+(4.2-1.8)+(3.5-0.1)+(3.5-0.9)+(4.2-0.1)*6
        =3.3+4.1*2+215.9*2+4.1*3+(4.2-1.8)+(3.5-0.1)+(3.5-0.9)+(4.2-0.1)*6
        =3.3+4.1*2+215.9*2+4.1*3+2.4+(3.5-0.1)+(3.5-0.9)+(4.2-0.1)*6
        =3.3+4.1*2+215.9*2+4.1*3+2.4+3.4+(3.5-0.9)+(4.2-0.1)*6
        =3.3+4.1*2+215.9*2+4.1*3+2.4+3.4+2.6+(4.2-0.1)*6
        =3.3+4.1*2+215.9*2+4.1*3+2.4+3.4+2.6+4.1*6
        =3.3+8.2+215.9*2+4.1*3+2.4+3.4+2.6+4.1*6
        =3.3+8.2+431.8+4.1*3+2.4+3.4+2.6+4.1*6
        =3.3+8.2+431.8+12.3+2.4+3.4+2.6+4.1*6
        =3.3+8.2+431.8+12.3+2.4+3.4+2.6+24.6
        =11.5+431.8+12.3+2.4+3.4+2.6+24.6
        =443.3+12.3+2.4+3.4+2.6+24.6
        =455.6+2.4+3.4+2.6+24.6
        =458+3.4+2.6+24.6
        =461.4+2.6+24.6
        =464+24.6
        =488.6
    答案:(3.4-0.1)+4.1*2+(216-0.1)*2+(4.2-0.1)*3+(4.2-1.8)+(3.5-0.1)+(3.5-0.9)+(4.2-0.1)*6=488.6
