用计算器探索规律学习评价

用计算器探索规律学习评价1．用计算器计算前3题，直接写出后3题的得数。1234.5679×9=1234.5679×18=1234.5679×27=1234.5679×36=1234.5679×45=1234.5679×54=2．不计算，运用规律直接填出得数。6×7=426.6×6.7=44.226.66×66.7=6.666×666.7=答案：1．1234.5679×9=1111.11111234.5679×18=2222.22221234.5679×27=3333.33331234.5679×36=4444.44441234.5679×45=5555.55551234.5679×54=6666.66662．6×7=426.6×6.7=44.226.66×66.7=444.2226.666×666.7=4444.2222
