Which division symbol was invented? When was the division symbol invented?

The use of this symbol to represent division first appeared in an algebra book published by the Swiss scholar Rennes in 1656, where a horizontal line was placed between two points to indicate the meaning of the average score. It was only a few years later that the book was translated into English, and it was gradually recognized and accepted.

The division symbol was invented by the ancestors of Europe, and the Chinese did not use this symbol. As for when it was invented, you have to ask the Australian boss, his son, and his son knows when his father invented it.

Which division symbol was invented? I don't think there's an accurate record of who invented the division symbol, but Chinese mathematics was very advanced in ancient times, so I think it should have been invented by Chinese people.

What is the starting point of the kitchen number?,When did your friend send it to you?,It's really used on the keyboard and computer.。

Out of the symbol, the inventor was really clever at that time, and now it is very convenient to use.

Generally speaking, I think this is a rule of the middle of the tour!

Invented in ancient times.

Ancient Rome. That's it, it's paid.

The invention of the division symbol was made before the horizontal mark.

If I'm not mistaken, it should be that you really invented it, and I hope it helps you.

Which aspect of this book do I say is good? And when was it discovered, it should be convenient for this ancient thing.

Is the best or your invention? Resend and multi-hair, understand a lot can be direct.

The division symbol was invented, and when was the starting symbol invented?

In our country, it should have been invented by foreigners, but I don't know who invented it, but it's a symbol used by foreigners anyway.

[The origin of division]: In ancient China, people mastered the division of numbers very early. It was first used in the pre-Qin period, or earlier.

In the Book of Numbers, which was formed at that time, there are 19 types of divisions in 7 categories, involving 55 items. Since before the Spring and Autumn Period and the Warring States Period B.C., after the "ninety-nine" table was used to calculate multiplication, people also summarized the method of calculating division with formulas. "Sun Tzu's Sutra" says:

The method of division is different from multiplication. "At that time, our country mainly used arithmetic and formulas to calculate division.

Extended information: The integer a is divisible by the integer b, a is called a multiple of b, b is called the factor or divisor of a, within the range of natural numbers) example and 6 is the factor of 6.

The factors of 6 are: 1 and 6, 2 and 3. The factors of 10 are: 1 and 10, 2 and 5.

The factors of 15 are: 1 and 15, 3 and 5.

When calculating the greatest common factor or the least common multiple, the factor needs to be a prime factor. The former is the product of the prime factors on the left, excluding the final factor at the bottom; The latter needs to be multiplied together with the final factor.

A: In division, if the dividend is divided by the divisor, the quotient obtained is a natural number without a remainder, then the dividend is said to be a multiple of the divisor, and the divisor and the quotient are the factors of the dividend.

b: We divide a composite number into the form of multiplying several prime numbers, and such prime numbers are called the prime factors of this composite number.

Division is one of the four operations. Knowing the product of two factors and one of the factors, the operation of finding the other factor is called division. If ab=c(b≠0), the operation of finding another factor a using the product c and the factor b is division, written as c b, which is read as c divided by b (or b divided by c).

where c is called the dividend, b is called the divisor, and the result a is called the quotient.

The division of numbers has long been mastered. The origin of the earliest division was used in the pre-Qin period, or earlier. Formed in the Book of Numbers, there are 19 kinds of divisions in 7 categories, involving 55 articles.

Since the Spring and Autumn Period and the Warring States Period before BC, after the multiplication method of calculating the ninety-nine table appeared in China, the method of calculating division with formulas was summarized. "Sun Tzu's Sutra of Calculation" says: The method of division is different from multiplication.

The "division symbol" was first used by the Varys (Wallis) in England and was later popularized in the UK and around the world. The meaning of multiplication is addition, and division is a calculation that is opposed to multiplication, and it means points, so Varys vividly represents division with " ".

Originally, this symbol was popular as a minus sign in continental Europe, and at first people used ":" to indicate division or ratio, and some people used the fractional line " to represent ratio, and later some people combined the two to become" "" in the work of the Swiss mathematician Raha officially used " " as a division sign.

The ancestors had to use the division of ants when encountering the distribution of food and other items in their daily lives, that is to say, division was invented in primitive societies, and human beings at that time existed in the form of tribes, and there was no state in imitation.

The division sign belongs to the symbol of the four operations, and the addition and subtraction signs in the four operations have only been used since the 15th century, and the multiplication and division signs appeared in the 17th century.

The division sign " is called the Wren mark because it was first used by the Swede Juhann Liuinrich Rahn (1622-1676) in an algebra book published in 1659. In 1668, the book was translated into English and published, and the symbol has become popular until now. He used a horizontal line to separate the two dots, which means decomposition, that is, the upper and lower denominators represent the numerator and denominator.

However, Leibniz, a well-known German scientist, advocated the substitution of : symbol. In 1666, Leibniz used the phrase ":" as a dividing sign, in countries such as Germany and the former Soviet Union, in one of his "The Art of Composition".

How do second-graders understand the knowledge of dividing?

The origin of the division sign.

The division sign used for division operations is called the Wren mark because it was first used by the Swede Wren in an algebra book published in 1659. In 1668, his book was translated into English and published, and the symbol has become popular until now.

In 1666, Leibniz used ":" for the first time in one of his "The Art of Composition" as a division sign, which was gradually used in general, and is now used in Germany, the former Soviet Union and other countries.

There are two ways to say the sign of (except for). One is that the symbol represents division in the form of fractions, and the addition above and below one represents the numerator and denominator, respectively. Another way of saying it is that when expressed as a fraction, the above and below the horizontal line is the symbol used to distinguish it from .

Leibniz, a well-known German scientist, believed that the symbol, although commonly used, is easily confused with x, which represents an unknown number. So he advocated the use of symbols instead. He also advocated the use of :

Alternate symbol for . However, these two symbols have not been implemented so far.

For a long time, the ancient Babylonians used the "reciprocal table" to express the divisor as a decimal place in the sexagesimal system, and to divide by multiplying the reciprocal of the divisor.

As for the notation of division, the Arabs used the method of adding a ** between two numbers to express division, and in 1631, the mathematician Altred also conceived the use of the symbol ":" to represent division, but it was not popularized.

Mathematically, the current division sign is officially used as a symbol for division operations, which is the work of the Swiss mathematician Hana. Hana was faced with the problem of dividing an integer into several parts, but there was no proper notation to represent the algorithm. So he put the Arabs for the small ** of division and the division mark of Otred":

Combining the two into one, Hana separated the two dots with a horizontal line segment "-": "from the middle, and a new sign for division was produced, which is now the divide.

In 1659, in his algebra published in Zurich, Hana officially used the current division sign as a symbol for division operations.
