    作业：求算式 (35.14-30.94)×22+(44.64-35.14)×24+(47.24-44.64)×28+(57.04-47.24)×28+(64.54-57.04)×30 的值.
    题型：数学计算
    解:
          (35.14-30.94)×22+(44.64-35.14)×24+(47.24-44.64)×28+(57.04-47.24)×28+(64.54-57.04)×30
        =4.2×22+(44.64-35.14)×24+(47.24-44.64)×28+(57.04-47.24)×28+(64.54-57.04)×30
        =4.2×22+9.5×24+(47.24-44.64)×28+(57.04-47.24)×28+(64.54-57.04)×30
        =4.2×22+9.5×24+2.6×28+(57.04-47.24)×28+(64.54-57.04)×30
        =4.2×22+9.5×24+2.6×28+9.8×28+(64.54-57.04)×30
        =4.2×22+9.5×24+2.6×28+9.8×28+7.5×30
        =92.4+9.5×24+2.6×28+9.8×28+7.5×30
        =92.4+228+2.6×28+9.8×28+7.5×30
        =92.4+228+72.8+9.8×28+7.5×30
        =92.4+228+72.8+274.4+7.5×30
        =92.4+228+72.8+274.4+225
        =320.4+72.8+274.4+225
        =393.2+274.4+225
        =667.6+225
        =892.6
    答案:(35.14-30.94)×22+(44.64-35.14)×24+(47.24-44.64)×28+(57.04-47.24)×28+(64.54-57.04)×30=892.6
