Development history
Mathematics (hanyu 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". 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.
Its plural form in English and the plural form in French plus -es form mathématiques, which can be traced back to the Latin neutral plural (mathematica), and Cicero from the Greek plural τ α μ α θ ι α ι κ? (ta mathē matiká).
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).
Mathematics originated from the early production activities of human beings, and the ancient Babylonians had accumulated some mathematical knowledge, which could be applied 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.
Mathematical logic focuses on putting mathematics on a solid axiomatic framework and studying the results of this framework. As far as it is concerned, it is the origin of Godel's second incomplete theorem, which is perhaps the most widely circulated achievement in logic. Modern logic is divided into recursion theory, model theory and proof theory, which are closely related to theoretical computer science.
Most of the mathematical symbols we use today were invented after16th century. Before that, mathematics was written in words, which was a hard procedure that would limit the development of mathematics. Today's symbols make mathematics easier for people to operate, but beginners are often afraid of it.
