The origin of the number is written in a hand copied newspaper

This won't help you, you can look it up in the 100,000 whys.

As early as the time of primitive man, people noticed the difference in the number of one sheep and many sheep, one wolf and the whole pack of wolves in production activities, and the concept of number slowly developed over time. The concept of number was probably as old as the use of fire, about 300,000 years ago, and it is no less significant to human civilization than the use of fire.

In the early days, people used their ten fingers to count, and when the fingers were not enough, people began to use "stone counting", "knotted rope counting" and "notching counting". After tens of thousands of years of development, it was not until about 5,000 years ago that there was a written notation and a corresponding notation system. Early counting systems were:

Ancient Egyptian pictographic numerals from around 3400 BC; Babylonian wedge-shaped figures from around 2400 BC; Chinese oracle bone inscription numbers from around 1600 BC; Greek Attica numerals from around 500 BC; Chinese calculations around 500 B.C.; Indian Brahmin numerals from around 300 BC and Mayan numerals of unknown date. These notation systems use different decimal systems, with the Babylonian wedge-shaped numerals in the sexagesimal system and the Mayan numerals in decimal except in the decimal system. The advent of the counting system has made a big step forward for human civilization, and with the continuous development of productive forces and the continuous improvement of numbers, mathematics has gradually developed.

1. Numbers and codes.

Numeric encoding is an encoding that uses only numbers and related special characters to represent data and instructions.

Most numeric encodings use positional notation, i.e., any number can be represented by the sum of some numbers. Depending on where these numeric codes are located in the representation, there are different values. That is, each different position has its own "right.""。

The decimal data system is the most familiar number system, but in data conversion and computer processing, it is difficult and even impractical to use the decimal data system, which requires the use of ten different circuit states to represent ten numeric symbols. However, there are many ways in which a circuit can represent two different states, and binary data systems are widely used.

The digital coding of digital data refers to the transformation of binary 0 1 digital data into a square wave waveform (digital signal) with a certain polarity, amplitude, bit rate, and jump rules.

2. Mathematical Development and Computer Technology.

In the past 50 years, mathematicians, applied mathematicians and statisticians have pioneered an extremely wide and colorful methods and concepts, which have formed a huge intellectual resource, and the technical development and technical realization of this resource is the birth of artificial intelligence application software in engineering technology. Mathematics has entered a period with greater potential impact on the development of technology, and computers have provided mathematics with an important channel to various fields of science and engineering technology, opening up a new era of mathematics.

Computer simulations and aided design, based on mathematics and computer graphics, are now widely used in all sectors of engineering technology. Mathematics and physicists can now reliably simulate very complex physical phenomena through computers. For example:

Aircraft design, spacecraft flight simulation, atomic bomb and hydrogen bomb tests, wind tunnel tests and other costly test projects can all provide profound insights into these aspects of research through computer simulation and mathematical analysis.

The electronic computer has become more and more deeply involved in all fields of mathematics itself, and it has liberated mathematicians from some tedious and rigid logical reasoning and the mental work of huge and complex calculations, so that their ingenuity can be applied more to truly creative work. It can also be used to effectively verify mathematical conjectures and theoretical results of mathematics. The successful proof of the computer for the super mathematical problem "four-color problem" has brought a huge impact to mathematics, and its deeper significance lies in the fact that the mathematical community has a new understanding of the huge potential of the computer.

The hand-copied report of the number is as follows:

The generation of numbers: People invented counting symbols in productive labor, called numbers. Numbers were gradually created by the ancient Indians in production and practice.

In ancient India, it was necessary to design and plan the construction of cities, and to calculate the movement of the sun, moon and stars for rituals, so mathematical calculations were born.

Rewriting of numbers: 1. Rewrite as a number in units of "10,000": remove the 4 "0s" at the end and add the word "10,000"; Rewrite it as a number in "100 million"; It is necessary to remove the eight "0s" at the end and add the word "100 million".

The reading of numbers: 1. First grading: from right to left, every four digits are one level; 2. Re-reading: read 100 million first: then read 10,000. Repent high read the last level, and 0 at the end of each level is not read.

How to write large numbers: 1. Grading first: dotted lines behind "100 million" and "10,000"; 2. Draw the frame: 3. Fill in the number; 4. "0" supplement; 5. Read it once you're done.

Approximate number of saves: Round to which one only looks at the latter of it.

The method of comparing the size of the number is cautious: 1. When the number of digits is different, the number of digits is large, and the number of digits is small. 2. When the number of digits is the same, start to compare from the first place from the left until the size is compared.

Natural numbers: like , , rotten before Jing are the most natural numbers, 0 is the smallest.

Knowledge of calculation tools: abacus, slide rule, calculator.

A number is a written symbol used to represent numbers, which was gradually created by the ancient Indians in the dust of production and practice. In ancient India, it was necessary to calculate the movement of the sun, moon and stars when performing sacrifices, so mathematical calculations were born.

Around 3000 B.C., the numbers of the inhabitants of the Indus Valley were more advanced and decimal calculations were used. By the third century B.C., a whole set of numbers had appeared in India, the most representative of which was the Brahmanical style, which was more commonly used at that time. It is characterized by the fact that each number from "1" to "9" has a special word, and modern numbers are evolved from this group of numbers.

0"This number did not appear until the multi-dynastic period, "0"Evolved from the dots. <>

There are several types of numbers, with Arabic numerals being the most prevalent. Arabic numerals were not invented by the Arabs but by the Indians, and should actually be listed as an Indian language, but they were first transmitted to Arabia and then to the world, so they are called "Arabic numerals.""。A number is a written symbol used to represent numbers.

Different counting systems can use the same number.

Westerners, who first came into contact with the Arabs and used these data, mistakenly thought that they had invented them, so they called these numbers Arabic numerals, causing this historical misunderstanding.

Later, the spread of the Sui Pai orange blind around the world, everyone agreed with the term "Arabic numerals", so that people in many parts of the world mistakenly thought that the Arabs invented the numbers, in fact, the Arabs began to widely use the number of words.

After it was spread to Europe, Europeans loved this set of convenient counting symbols, and although people later learned the truth of the matter, they never corrected it because they got used to it.
