Tianyuan is a common quadratic equation. Now basically anyone who has read junior high school can easily solve this equation, but it was difficult to solve this equation in ancient times. At this time, a great mathematician, Li Zhi, who is also a major contributor to celestial art, worked out this troublesome equation.

The evolution of celestial magic appeared as early as the Tang Dynasty, and the mathematician Wang Xiaotong created a kind of? With the issuer? The solution was created by a mathematician named Jia Xian in the Northern Song Dynasty? Multiplication method? And propose? What is the original picture of the medicine method? Then Qin was promoted vigorously. Multiplication method? It has become a method to find the positive root of any higher order equation.

Later, mathematician Li Zhi spent 10 years writing a book called "Round Sea Mirror", which listed many solutions to celestial magic. However, this book is too abstruse and professional for many people to understand, so Li Zhi wrote a relatively simple book "An Ancient Yan Duan", which sorted out the common celestial wonders from the superficial to the profound.

Up to now, Li Zhi's two books, Measuring the Circle of the Sea Mirror and Yi Gu Yan Duan, are the most original and complete works on the calculation method of monty. At this time, they only stayed in the period of only one unknown, and then four higher-order unknown equations began to appear. At this time, Zhu Shijie compiled "Four Jade Juanjian", which solved the problem of how to remove the unknowns of higher-order equations.

At this time, the art of Heaven has basically taken shape. Later, Bao Yanting, a bibliophile in the Qing Dynasty, printed a series of books lacking in knowledge and collected the basic contents of studying heavenly arts for later generations. Mathematicians Jiao Xun and Li Rui jointly compiled Tianyuan Yi Shi and General History of Prescription Science. Later, these two books introduced celestial art very clearly.

Later, Tian and modern equation theory finally merged into one, which became the fundamental source for us to calculate polynomial equations now. The formation of celestial elements is of great significance to the mathematical development of the whole world. According to the introduction of western history, their polynomial algorithm was calculated more than 300 years later than ours.
