Unary equations.

- The origin of the equation.

In the sixteenth century, with the emergence of various mathematical symbols, especially the French mathematician Vedtron.

After establishing a more systematic symbol to represent unknown and known quantities"Equations with unknowns"

This specialized concept appeared, and at that time the Latin called it"aequatio"in English"equation".

Around the seventeenth century, European algebra was first introduced to China"equation"for"Equality.

At that time, the power of China's ancient culture was still relatively strong, and the modern science and culture of the West were not timely.

Widely spread in our country and has a relatively large impact, therefore"Algebra"Together"Equality. "Wait for this.

Some disciplines or concepts are only studied and studied by a very small number of people.

In the middle of the nineteenth century, modern Western mathematics was once again introduced to China. In 1859, Li Shanlan and the British.

The missionary Willy Ari was the English mathematician Virtue. Morgan's translation. Plum. Great.

The two paid great attention to the correct translation of mathematical terms, and they borrowed or created nearly 400 numbers.

Many of the Chinese translations of the nouns that have been learned have been used to this day. Among them,"equation"The translation of the name is borrowed.

I used the ancient ones of our country"Equations"word. In this way,"Equations"The term was first meaningful"Contains unknown.

The equation of numbers. In 1873, another disseminator of Western science in the early modern period of China, Hua Yufang, was passed on to the British.

The Priest Ranja co-translated the English of Walris, and they put it"equation"Translated as"Equations

formula", they mean,"Equations"with"Equations"It should be distinguished that the equation still refers to the meaning, while the equation refers to"There is an equation of unknowns".Chinese. Fu's proposition is in.

It has been widely adopted for a long time. It was not until 1934 that the Chinese Mathematical Society conducted a first trial of nouns.

Check, OK"Equations"with"Equations"The two have the same meaning. Broadly speaking, they refer to a unary n times.

Equations and systems of equations that are connected by several equations. In the narrow sense, it refers specifically to unary nth order equations.

Since"Equations"with"Equations"synonymous, then"Equations"It's even more concise and straightforward.

Tang Seng and the four of them took a plane to travel, and the plane crashed on the way, but there were only three parachutes So, Tang Seng said, everyone come to answer the question, and jump down if you can't answer Tang Seng: Wukong, how many suns are there in the sky?

Tang Seng: Okay, I'll give you a handful too

Tang Seng: Bajie, what is the name of those 10,000 people Bajie had to jump again The third time, the four of them took a plane to travel again, and there was an accident on the way At this time, Bajie said: Master, you don't need to ask, I will jump by myself Then I jumped
