今天,我和爸爸正在家里闲着无聊。爸爸说:“想听故事吗?”“好啊。”我回答道。“从前,村里有一个小孩,他很聪明,有一天,一个财主给他一元钱去买调味料。可是钱不够呀。财主吩咐小孩买油盐葱,油6角,盐3角,葱2角,还差1角。可是小孩却一样不差地买回来了,还没缺斤短两。”我想得头都破了,那小孩是怎么买到的?还差一角钱啊?不过我不能就这样放弃呀。我把数学书翻遍了,终于有了灵感:我们学过四舍五入法呀,应该使用它! Today, my father and I are idle at home. Dad said: “Want to hear the story? ” “Well. ” I replied. Once upon a time there was a child in the village who was very clever. One day a rich man gave him a dollar to buy seasoning, but the money was not enough. The rich man told the children to buy oil and salt, Angle, but also a corner .But the child is equally good buy back, not short of jin short. “” I think too bad, that child is how to buy it? I can not give up like this. I rummage through the book, and finally inspired: we learned rounding it, you should use it!
