〖1/1算式〗
    作业：求算式 (3.04+0.2)×(4+0.2)×0.1×2+(3.04+0.2)×(6.5+0.2)×0.1×1+(6.98+0.2)×(2.8+0.2)×0.1×1 的值.
    题型：数学计算
    解:
          (3.04+0.2)×(4+0.2)×0.1×2+(3.04+0.2)×(6.5+0.2)×0.1×1+(6.98+0.2)×(2.8+0.2)×0.1×1
        =3.24×(4+0.2)×0.1×2+(3.04+0.2)×(6.5+0.2)×0.1×1+(6.98+0.2)×(2.8+0.2)×0.1×1
        =3.24×4.2×0.1×2+(3.04+0.2)×(6.5+0.2)×0.1×1+(6.98+0.2)×(2.8+0.2)×0.1×1
        =3.24×4.2×0.1×2+3.24×(6.5+0.2)×0.1×1+(6.98+0.2)×(2.8+0.2)×0.1×1
        =3.24×4.2×0.1×2+3.24×6.7×0.1×1+(6.98+0.2)×(2.8+0.2)×0.1×1
        =3.24×4.2×0.1×2+3.24×6.7×0.1×1+7.18×(2.8+0.2)×0.1×1
        =3.24×4.2×0.1×2+3.24×6.7×0.1×1+7.18×3×0.1×1
        =13.608×0.1×2+3.24×6.7×0.1×1+7.18×3×0.1×1
        =1.3608×2+3.24×6.7×0.1×1+7.18×3×0.1×1
        =2.7216+3.24×6.7×0.1×1+7.18×3×0.1×1
        =2.7216+21.708×0.1×1+7.18×3×0.1×1
        =2.7216+2.1708×1+7.18×3×0.1×1
        =2.7216+2.1708+7.18×3×0.1×1
        =2.7216+2.1708+21.54×0.1×1
        =2.7216+2.1708+2.154×1
        =2.7216+2.1708+2.154
        =4.8924+2.154
        =7.0464
    答案:(3.04+0.2)×(4+0.2)×0.1×2+(3.04+0.2)×(6.5+0.2)×0.1×1+(6.98+0.2)×(2.8+0.2)×0.1×1=7.0464
