There are several ways to express numbers, and how to express language with numbers?

<>1. Numerical representation can be divided into different types according to different perspectives. The number of slaves can be divided into signed numbers and unsigned numbers; The representation of the symbol of the slave number can be divided into the true value and the machine number; From the perspective of the number system, it can be divided into binary numbers.

decimal numbers, octal numbers, hexadecimal numbers, etc.; From the perspective of computer coding, the notation of numbers includes original code, inverse code and complement code; For the representation of decimal points, it can be divided into fixed-point notation and floating-point notation.

2. Arabic numerals.

It is a common number in the world today. Originally by ancient India.

It was invented by man, then introduced to Europe by the Arabs, and then modernized by the Europeans. It is precisely because of the spread of the Arabs that it has become the key node for this kind of number to be used internationally, so people call it "Arabic numerals".

3. Arabic numerals are composed of 10 counting symbols: 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. Take the place value method, the high position is on the left, the low position is on the right, and the writing is from left to right. With the help of some simple math symbols.

The system can explicitly represent all rational numbers. In order to represent very large or extremely small numbers, scientific notation was created on the basis of Arabic numerals.

There are 108,000 species.

Symbols: Arabic, Chinese characters (one, one).

Languages: English, French、。。

Sign language, flag language, bell ringing, light 、。。

Items: Apples, pencils, flowers, shoes, .

The way to express language in numbers is, for example, I love you with 521, thank you with 3q, and long with 99. Mathematical language is the carrier of mathematical thinking, is a kind of expression of scientific thought of the general language and the best carrier of mathematical thinking, mathematical language can be divided into abstract mathematical language and intuitive mathematical language, including mathematical concepts, terms, symbols, formulas, graphics, etc.

Mathematical language can be summarized into three categories: text language, symbolic language, and graphic language, and various forms of mathematical language have their own advantages, such as the concept is tightly defined, the essential attributes are revealed, the terminology is introduced into science, nature, the system is complete and standardized, the symbol is concise, the writing is convenient, and the mathematical content is expressed in a concentrated manner, and the formula dissolves the relationship in the form, which is helpful for operation, easy to think, and intuitive for graphic expression, helpful for memory, helpful for thinking, and beneficial to problem solving.

Characteristics of the digital language

Logical, mathematics takes a strict logical structure as the skeleton of the discipline, and if it violates logic, it violates the true principle of mathematics, and the language of mathematics must conform to the objective law, that is, the speech must be grounded, cause and effect, premise and conclusion, either by cause and effect, or by effect, which is enough to be reflected in the process of solving problems in logical thinking.

Accuracy, every mathematical concept, symbol, term has its precise meaning, there is no ambiguous or ambiguous vocabulary, the conclusion is wrong, the subject of mathematics involves computational measurement, in many cases requires the accuracy of the data, under different conditions, the conclusion in mathematics will change.

Conciseness, mathematical language has obvious conciseness, it uses the least linguistic symbols to express the most complex formal relationships. Mathematical language greatly shortens the length of language expression, makes narration, calculation and reasoning clearer and more unambiguous, mathematical language is not only the simplest and most understandable language, but also the most refined language, conciseness is the most prominent manifestation of mathematical language.

Professionalism, in fact, the professionalism of mathematics is obvious, as can be seen from its quantity, and these professional terms are rarely used in daily life, for example, equations, quotients, products, diagonals, etc., so we must consciously use these specialized mathematical languages, and to use them correctly, and develop the habit of mathematical language norms.

The numbers are represented as follows:

1. Chinese lowercase numbers.

One, two, three, four, five, six, seven, eight, nine, ten.

2. Chinese capital numbers.

Zero, one, two, three, four, Wu, Lu, Qihuaiyou, 捌, Jiu, pick.

3. Arabic numerals.

4. Roman numerals use seven Roman letters as numbers.

1)、x（10)、c（100)、m（1000)，v（5)、l（50)、d（500)。

Common Number Symbols:

2, (1), (2), (3), (4), (5), (6), (7), (8), (9), (x).

4, (1), (2), (3), (4), (5), (6), (7), (8) Yanyan, (9), (10).
