1. Calculation method: Calculate with a method similar to vertical calculation, arrange the numbers bit by bit, and add and subtract bit by bit.
2. Introduction method: For the addition, subtraction, multiplication and division of integers, fractions and negative numbers, it is calculated through prescribed steps and methods.
3. Arithmetic methods: including basic operations such as addition, subtraction, multiplication and division, as well as advanced operations such as root and cube.
4. Calligraphy method: Calculate by writing numbers, such as using bars to represent negative numbers and apostrophes to represent decimals.
5. Cycle method: Use the characteristics of cycle to solve some complex mathematical problems, such as calculating the square root and solving equations by cycle.
Algorithm unification is an important work created by Yang Hui, a mathematician in Ming Dynasty. The mathematical algorithm and mathematical knowledge at that time were introduced in detail. This book contains many contents about arithmetic, algebra, geometry and other fields, which has had an important impact on the development of mathematics in the Ming Dynasty.
Yang Hui was a famous mathematician and scholar in Ming Dynasty. In this book, he systematically expounded some mathematical methods and skills such as arithmetic operation, solving equations and geometric figures. The title "The Theory of Algorithm Unity" means to summarize the essence of various algorithms, and it was one of the important works in the field of mathematics at that time.
The creative history of algorithm unification.
Yang Hui wrote "Algorithm Unification" from the end of 13 to the beginning of 14, and lived in the late Southern Song Dynasty and early Yuan Dynasty in China. This period coincided with the vigorous development of mathematics in China, and many mathematicians were exploring various fields of mathematics, including arithmetic, algebra and geometry.
Yang Hui's "Arithmetic Unity" is regarded as his masterpiece in his later years, which contains mathematical knowledge and algorithms summarized by years of research. This book covers all kinds of mathematics, including arithmetic, equations, geometry, number theory and so on. The purpose of its creation is to systematically summarize and inherit the mathematical achievements at that time and provide reference for future generations to study and study.
