| Outline of Final Research Achievements |
Towards the books "Haidao Suanjing", "Sunzi Suanjing", "Zhang Qiujian Suanjing", "Wucao Suanjing", and "Jigu Suanjing", we have added mathematical and cultural-historical considerations, and published as articles their translations into Japanese and their annotations.
We explianed that the methods of "Haidao Suanjing" is the combination of the same techniques as in the problems 17 - 24, Chapter 9 of "Nine Chapters of Mathematical Arts", which is particular version of Proposition 43, Volume 1 of Euclid's "Elements". We also showed that the solution method for cubic equations described in "Jigu Suanjing" is a generalization of the method to extract cubic root described in "Nine Chapters", and on the other hand, clarified the gap between them.
Furthermore, we clarified the reason why the existence of the positive solution of its cubic equation is guaranteed.

| Academic Significance and Societal Importance of the Research Achievements |
以前の研究課題による秦漢期の成果と合わせ、本研究によって秦代から唐代に至る中国数学の研究資料の用に足る訳注がそろったことになる。その多くは完訳としては初めてであろう。
恩恵の一例として、前漢の『算数書』での平方根の近似分数、後漢の『九章算術』の開平方・開立方、三国魏の劉徽注による開帯従平方（2次方程式）、唐の『緝古算経』の開帯従立方（3次方程式）という展開が、一貫して図形の取り尽くしという考え方によるものであったこと、それぞれの段階にある困難とが明らかになった。
