A mathematical term, seeking meaning, what are the mathematical terms?

Individual income tax is a tax levied on various taxable income obtained by individuals (natural persons). The Individual Income Tax Law of the People's Republic of China was promulgated by the Standing Committee of the Eighth National People's Congress on October 31, 1993 and came into force on January 1, 1994. On January 28, 1994, the Regulations for the Implementation of the Individual Income Tax Law of the People's Republic of China were promulgated

Individual income tax refers to individuals who have a domicile in China, or who have not been domiciled but have resided in China for one year, and who have no domicile and do not reside in China or have resided for less than one year but have income from China. Including Chinese citizens, individual industrial and commercial households, foreign individuals, etc.

The salary is to be paid to the state.

In accordance with the provisions of Article 2 of the Individual Income Tax Law of the People's Republic of China, individuals shall pay individual income tax on the following income:

1.Income from wages and salaries.

2.Income from production and operation of individual industrial and commercial households.

3.Income from contracted and leased operations of enterprises and institutions4Income from remuneration for labor services.

5.Author's remuneration.

6.Royalties are royalties.

7.Income from interest, dividends, bonuses.

8.Income from the lease of property.

9.Income from the transfer of property.

10.Incidentally.

11.Other income determined to be taxed by the Ministry of Finance.

Mathematical terms are as follows:

1. Squared. Squared is an operation, for example, the square of a represents a a, abbreviated as a, or written as a a (the first square of a multiplied by a is equal to the second power of a), for example, 4 4 = 16, 8 8 = 64, and the square sign is 2.

2. Cube. The cube is also called the cubic shape. Multiplying three identical numbers is called the cube of that number. For example, 5 5 5 is called the cube of 5, which is written as 5.

3. Equations. An equation is an equation that contains unknowns. It is an equation that expresses the equality relationship between two mathematical formulas (such as two numbers, functions, quantities, operations), and the value of the unknown number that makes the equation true is called the "solution" or "root".

The process of finding the solution of an equation is called "solving an equation."

4. Solution. A solution set is a mathematical term that refers to the set of all the solutions of an equation (group) or inequality (group) as elements, which is called the solution set of the equation (group) or inequality (group). There are three ways to represent the set of solutions:

Enumeration, descriptive, and illustrative. As an important tool in mathematics, solution sets have a wide range of applications in mathematics.

5. Arrangement. Permutation, in general, takes out m (m n) elements from n different elements and arranges them in a certain order, which is called taking out a permutation of m elements from n elements. In particular, when m = n, this arrangement is called a full permutation.

all permutation)。

There are many nouns in mathematics, and here are some common mathematical terms:

Number theory: integers, primes, composite numbers, factors.

Geometry: points, line segments, angles, triangles, squares, rectangles, circles, ellipses, parabolas.

Analytic geometry: planar Cartesian coordinate system, polar coordinate system, curve, surface.

Linear algebra: matrices, vectors, systems of linear equations, determinants, eigenroots, eigenvectors.

The definition of mathematics is the science of the relationship between the form and quantity of space, and its basic elements are: logic and intuition, analysis and construction, generality and individuality.

In fact, with the development of mathematics, people's understanding of mathematics is also changing, the famous polymath of ancient Greece Proclus commented on mathematics as follows: mathematics, as the expression of human thinking, reflects people's aggressive will, careful reasoning and the pursuit of perfection. Later Wittgenstein considered mathematics to be an invention, Turing argued that mathematics was a discovery, and today we think that mathematics may be both an invention and a discovery.

If the development of mathematics is divided into several stages, it can be roughly divided into three periods:

1. Classical Mathematics Period. His research interests include numbers, algebraic equations, and elementary geometry.

2. The period of modern mathematics. Marked by the birth of calculus, it is set against the backdrop of physical motion in the macroscopic world.

3. The period of modern mathematics. Marked by the birth of set theory, its distinctive feature is the formalism advocated by Hilbert.

The depth and breadth of the development of modern mathematics have far exceeded people's imagination, and it is difficult for even the greatest mathematician to understand the whole of modern mathematics.

According to the French school of Nicolas Bourbaki, "Many mathematicians have taken their place in the kingdom of mathematics and are reluctant to leave." Not only do they almost completely ignore things that are irrelevant to their area of expertise, but they also fail to understand the language and terminology used by their colleagues in a corner far from them.

Mathematics is a discipline that studies concepts such as quantity, structure, change, space, and information, and belongs to a kind of formal science from a certain point of view. Mathematics is a universal means of human beings to describe the abstract structure and pattern of things, and all mathematical objects are inherently artificially defined. In this sense, mathematics belongs to the formal sciences, not the natural sciences.

In ancient China, mathematics was called arithmetic, also known as arithmetic, and finally changed to mathematics Arithmetic in ancient China was one of the six arts.

Mathematics originated from the early production activities of human beings, and the ancient Babylonians had accumulated a certain amount of mathematical knowledge since ancient times, and could apply practical problems From the perspective of mathematics itself, their mathematical knowledge was only obtained by observation and experience, and there was no comprehensive conclusion and proof, but it was also necessary to fully affirm their contributions to mathematics.

mathematics [English: mathematics, from the ancient Greek máthēma); Often abbreviated as math or maths], it is a discipline that studies concepts such as quantity, structure, change, space, and information.

Mathematics is a universal means for human beings to strictly describe the abstract structure and pattern of things, and can be applied to any problem in the real world. In this sense, mathematics belongs to the formal sciences, not the natural sciences. Different mathematicians and philosophers have a range of opinions on the exact scope and definition of mathematics.

In the historical development and social life of mankind, mathematics plays an irreplaceable role, and it is also an indispensable basic tool for learning and researching modern science and technology.
