| Abstract: | Tongwen Suanzhi includes quadratic,cubic and high degree equations.Li Zhizao wrote Western equation solutions with Chinese traditional way.He also told us how to confirm the digit of the equation root and how to get the second-order digit of the equation root.In addition,Li Zhizao gave the method to solve the equations without integer roots in Tongwen Suanzhi.Considering the above analysis,the author points out that Li Zhizao tried to merge the Western and Chinese mathematics with Tongwen Suanzhi. |
