It is a proverb or idiom, which comes from China folklore and mathematical thinking. It describes a strange mathematical phenomenon, that is, by adding or multiplying three numbers, the final result will be one. This proverb has a far-reaching influence in China culture. It is not only used to describe mathematical laws, but also to describe the changes and development of things.
The proverb "three three get 999" can be understood as a single number "three" superimposed nine times to get "999". Here "three" represents the basic unit or state, while "999" represents the limit state. The limit state of "999" can be obtained by superimposing "three" for nine times, and a convergence phenomenon can be seen.
In China culture, "3399991" is also widely used in various fields to describe the development and changes of things. It conveys the meaning of convergence, unity and regression, and emphasizes the circulation and normalization of things in the development process.
This way of thinking is deeply rooted in China's traditional philosophy and culture. For example, Taoism's "Taoism is natural" and Buddhism's "all laws have no self" all emphasize the concept of the unity of all things.
Mathematically:
The explanation of "999" obtained by adding or multiplying three numbers can be: three numbers add 3+3+3+3 = 27, and 2+7=9, and the final result is 9. Multiply three numbers: 3 * 3 * 3 * 3 * 3 * 3 =19683, 1+9+6+8+3=27, 2+7=9, and the final result is 9.
This strange mathematical phenomenon seems counterintuitive, but it also reflects some laws and properties in mathematics. For example, the number 9 has special properties in mathematics. Whether you add or multiply any number, the final result will return to 9 itself.
