    作业：求算式 (7.28+0.2)×(2.8+0.2)×0.1×1+(7.72+0.2)×(6.5+0.2)×0.1×1+(7.72+0.2)×(3.74+0.2)×0.1×1 的值.
    题型：数学计算
    解:
          (7.28+0.2)×(2.8+0.2)×0.1×1+(7.72+0.2)×(6.5+0.2)×0.1×1+(7.72+0.2)×(3.74+0.2)×0.1×1
        =7.48×(2.8+0.2)×0.1×1+(7.72+0.2)×(6.5+0.2)×0.1×1+(7.72+0.2)×(3.74+0.2)×0.1×1
        =7.48×3×0.1×1+(7.72+0.2)×(6.5+0.2)×0.1×1+(7.72+0.2)×(3.74+0.2)×0.1×1
        =7.48×3×0.1×1+7.92×(6.5+0.2)×0.1×1+(7.72+0.2)×(3.74+0.2)×0.1×1
        =7.48×3×0.1×1+7.92×6.7×0.1×1+(7.72+0.2)×(3.74+0.2)×0.1×1
        =7.48×3×0.1×1+7.92×6.7×0.1×1+7.92×(3.74+0.2)×0.1×1
        =7.48×3×0.1×1+7.92×6.7×0.1×1+7.92×3.94×0.1×1
        =22.44×0.1×1+7.92×6.7×0.1×1+7.92×3.94×0.1×1
        =2.244×1+7.92×6.7×0.1×1+7.92×3.94×0.1×1
        =2.244+7.92×6.7×0.1×1+7.92×3.94×0.1×1
        =2.244+53.064×0.1×1+7.92×3.94×0.1×1
        =2.244+5.3064×1+7.92×3.94×0.1×1
        =2.244+5.3064+7.92×3.94×0.1×1
        =2.244+5.3064+31.2048×0.1×1
        =2.244+5.3064+3.12048×1
        =2.244+5.3064+3.12048
        =7.5504+3.12048
        =10.67088
    答案:(7.28+0.2)×(2.8+0.2)×0.1×1+(7.72+0.2)×(6.5+0.2)×0.1×1+(7.72+0.2)×(3.74+0.2)×0.1×1=10.67088
