What is the knowledge of mathematics and what is the common knowledge of mathematics?

Mathematical knowledge is all-encompassing, up to astronomy and geography, down to trivial matters involving mathematical knowledge, but the most basic book is nothing more than the content taught by kindergarten and small generaries: understanding the size of numbers, addition, subtraction, multiplication and division of four operations, at most plus fractions, decimal knowledge, basically is the mathematical knowledge used in daily life, proficient in operations and the so-called "application problem" solution, and then master a little about the area, volume calculation is better. As for other "mathematical knowledge", even top mathematicians may find it difficult to say what "mathematics" ultimately includes, because science and technology are a process of continuous exploration and development.

Summary of junior high school mathematics knowledge points.

First, the basics.

1. Numbers and algebra a, numbers and formulas: 1. Rational numbers, rational numbers, plates, rational numbers: integers, weighted positive integers, 0 negative integers, fractions, positive fractions, negative fractions.

Number axis: Draw a horizontal straight line, take a point on the line to represent 0 (origin), select a certain length as the unit length, and specify the right direction on the line as the positive direction, and the number axis is obtained. Any rational number can be represented by a point on the number line.

If the two numbers differ only by sign, then we call one of the numbers the opposite of the other, and we call the two numbers opposites of each other. On the number line, two points representing opposite numbers to each other are located on opposite sides of the origin and are at equal distances from the origin. The number represented by two dots on the number line, the right side is always larger than the left side.

Positive numbers are greater than 0, negative numbers are less than 0, and positive numbers are greater than negative numbers.

Addition, subtraction, multiplication and division, fractions, unit conversion, too much.

The general knowledge of mathematics is as follows:

1. Archimedes, known as the "father of mechanics", has more than 10 kinds of mathematical works in the world, and Archimedes once said: Give me a fulcrum, and I can lift the earth. This sentence tells us to have the courage to find this fulcrum, to use it to find the truth.

2. The first to use the small dot as a decimal point was a German mathematician named Kravis.

4. "Tangram" is a kind of puzzle toy in ancient China, which is composed of seven thin plates that can be put together into a large square, and the pattern of the spelling out is varied, and it was later spread to foreign countries called Tang Tu.

5. Legend has it that as early as 4,500 years ago, our ancestors used carved leaks to keep time.

6. China is the first country to use rounding for calculation.

7. Euclid's most famous work, Geometry Primitives, is the foundation of European mathematics, proposing five major postulates and developing into Euclidean geometry, which is widely regarded as the most successful textbook in history.

8. Zu Chongzhi, a mathematician, astronomer and physicist in the Southern and Northern Dynasties of China, calculated the value of pi to the 7th digit.

9. The Dutch mathematician Ludolph calculated pi to the 35th place.

What to know about mathematics:1. The number of copies The number of copies The total number of copies The number of copies The number of copies The number of copies per copy.

Multiples Multiples Multiples 1 Multiples Multiples Multiples 1 Multiples.

3. Speed Time Distance Speed Time Distance Time Distance.

4. Unit price, quantity, total price, unit price, total quantity, total price, quantity, unit price.

5. Work efficiency, working hours, total work, total work, working hours, total working hours, working hours, work efficiency.

6. Add the number and add the number and add one plus the other add.

7. Subtracted Reduced Difference Subtracted Difference Subtracted Difference Subtracted Decreased.

8. Factor Factor Product One Factor Another Factor.

9. Dividend, divisor, quotient, divisor, quotient, divisor, divisor.

1. Mathematics is a discipline that studies concepts such as quantity, structure, change, space and information, and belongs to a kind of formal science from a certain point of view.

2. Shujing Qingxue plays an irreplaceable role in the development of human history and social life, and is also an indispensable basic tool for learning and researching modern science and technology.

3. Mathematics originated from the early production activities of human beings, and the ancient Babylonians had accumulated a certain amount of mathematical knowledge since ancient times, and could apply practical problems or halls. From the perspective of mathematics itself, their mathematical knowledge is only obtained through observation and experience, and there is no comprehensive conclusion and proof, but it is also necessary to fully affirm their contributions to mathematics.

4. Mathematics is used in many different fields, including science, medicine, and economics. The application of mathematics in these areas is often referred to as applied mathematics and sometimes provokes new mathematical discoveries and the development of entirely new mathematical disciplines. Mathematicians also study pure mathematics, that is, mathematics itself, without aiming for any practical application.

While much of the work begins with the study of pure mathematics, it may be possible to find suitable applications later.
