Draw a horizontal line in the middle of this box to indicate the dividing line of average score. Draw a few small squares of the same size above and below, respectively, to indicate the number of average points.

average score

The average score is different from the average, which is an idea used to divide things. It means that when dividing an object, the numbers obtained by each part should be equal. Generation of average score: when people divide things, they often demand "fairness". In order to be fair, when they divide things, they need to get the same amount. The average score is thus generated.

Mathematics is a subject that studies concepts such as quantity, structure, change, space and information. Mathematics is a universal means for human beings to strictly describe and deduce the abstract structure and mode of things, and can be applied to any problem 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.

The three main mathematical definitions are called logicians, intuitionists and formalists, each of which reflects a different school of philosophical thought. Everyone has serious problems, no one generally accepts it, and no reconciliation seems feasible.

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.

Mathematical language is also difficult for beginners. How to make these words have more accurate meanings than everyday language also puzzles beginners. For example, the words "open" and "domain" have special meanings in mathematics.

Mathematical terms also include proper nouns such as embryo and integrability. But these special symbols and terms are used for a reason: mathematics needs accuracy more than everyday language. Mathematicians call this requirement for linguistic and logical accuracy "rigor".
