《科学画报》九四年第七期刊登了美国智力游戏设计家萨姆·洛伊德于一个多世纪前(1882年)出的一道名题。题目是用7个阿拉伯数字和8个点构成一个数学式,要求运算后所得的数尽可能接近82,所用这些点可以作为小数点。也可以作为表示循环小数的循环节。如1/3= In the seventh issue of the “Science Pictorial” in 1949, a famous title was published by Sam Lloyd, the American intellectual game designer, more than a century ago (1882). The topic is to construct a mathematical formula using 7 Arabic numerals and 8 points. The number obtained after the operation is as close as possible to 82, and these points can be used as decimal points. It can also be used as a loop section that represents a decimal point. If 1/3=
