Introduction to mathematics:

1, mathematics [English: Mathematics, from ancient Greece μ? θξμα(máthēma); Often abbreviated as math or maths], it is a discipline that studies concepts such as quantity, structure, change, space and information.

2. Mathematics is a universal means for human beings to strictly describe and deduce abstract structures and patterns of things, and can be applied to any problems in the real world. All mathematical objects are artificially defined in essence. In this sense, mathematics belongs to formal science, not natural science. Different mathematicians and philosophers have a series of views on the exact scope and definition of mathematics.

Mathematics plays an irreplaceable role in the development of human history and social life, and it is also an indispensable basic tool for studying and studying modern science and technology.

History of mathematics:

1, Mathematics (Chinese Pinyin: shùXué;; ; Greek: μ α θ η μ α κ; English: mathematics or maths), whose English comes from the ancient Greek word μθξμα(máthēma), has the meaning of learning, learning and science. Ancient Greek scholars regarded it as the starting point of philosophy and the "foundation of learning".

2. In addition, there is a narrow and technical meaning-"mathematical research". Even in its etymology, its adjective meaning is used to refer to mathematics whenever it is related to learning.

3. Its plural form in English and its plural form in French plus -es constitute mathématiques, which can be traced back to the Latin neutral plural (mathematica), and Cicero from the Greek plural τ α θ ι α τ κ? (Tamatika)

4. In ancient China, mathematics was called arithmetic, also called arithmetic, and finally it was changed to mathematics. Arithmetic in ancient China was one of the six arts (called "number" in the six arts).

5. Mathematics originated from the early production activities of human beings, and ancient Babylonians accumulated certain mathematical knowledge and could apply it to practical problems. As far as mathematics itself is concerned, their mathematical knowledge is only obtained through observation and experience, and there is no comprehensive conclusion and proof, but their contribution to mathematics should also be fully affirmed.

6. The knowledge and application of basic mathematics is an indispensable part of individual and group life. The refinement of its basic concepts can be found in ancient mathematical documents of ancient Egypt, Mesopotamia and ancient India. Since then, its development has continued to make small progress. But algebra and geometry at that time were still in an independent state for a long time.
