In ancient times, people used fingers, stones, ropes and other tools to count and calculate, and then gradually developed various calculation methods and tools, such as abacus and calculation.
The original meaning of arithmetic is calculation and statistics, such as accounting and arithmetic. Later, the word "calculation" gradually expanded to other fields, such as calculation and planning. Used to express planning and consideration.
During the evolution of Chinese characters, many changes have taken place in the writing methods of computational characters, and finally modern writing methods have been formed.
Purpose of calculation:
1, think, estimate: hello, he has a conscience, etc.
2. Plan, scheme: if calculated, counted, etc.
3, arithmetic, recognition: if you have the final say, calculate, etc.
4. Accounting settlement: for example, accounting for wages.
5. Investigate responsibility: such as calculating old accounts and general ledger.
The meaning of arithmetic:
To find out why we should learn mathematics well, we must first understand the importance of mathematics itself. Everything in the world has two sides: number and shape. Mathematics, as a science that studies the quantitative relationship and spatial form in the real world, excludes other specific characteristics of matter and only studies the whole world from the perspective of number and form. The role and position of mathematics can be summarized as follows.
Mathematics, as an important compulsory course from primary school to middle school to university, is an indispensable knowledge for human beings, which is beyond doubt. Many human discoveries are like passing clouds, and many disciplines establish new theories by overthrowing previous conclusions; However, the development of mathematics in past dynasties is not that future generations destroy the achievements of predecessors, but that each generation of mathematicians adds a new layer of architecture on the basis of the original architecture.
The conclusion of mathematics often has eternal significance. Euclid was an ancient Greek mathematician more than 2000 years ago. However, the geometry named after Euclid still plays an important role. Pythagorean theorem, instead of being dismissed as archaic, is called the eternal first theorem, which is highly respected and applied repeatedly, which fully illustrates this point.
