1, queen of mathematics and science; Number theory, the queen of mathematics.

2. Pure mathematics enables us to discover concepts and laws related to these concepts, which give us the key to understand natural phenomena.

3. Power is my favorite operation. The number obtained by power has an absolutely symmetrical shape and an unusually gorgeous color. The larger the value, the more exquisite and complex it is.

4. There is no maximum natural number, and the number of natural numbers is infinite.

Mathematics is the most powerful knowledge tool left by human knowledge activities and the root of some phenomena. Mathematics is immutable and exists objectively, and God will build the universe according to the laws of mathematics.

6. It may sound strange, but the power of mathematics lies in that it avoids all unnecessary thinking and surprisingly saves mental work.

7. Prime numbers can only be divisible by one and itself. In the infinite sequence of natural numbers, they are in their respective positions. Like all other numbers, they are squeezed by two numbers, but the distance between them is one step farther than all other numbers. They are suspicious and lonely numbers.

8. The lines of mathematics are full of magical optical phantoms, which are mysterious; The lines of mathematics are full of harmonious rhythm and abstract rainbow, which makes it difficult to give up; Between the lines of mathematics, there is a spark of human wisdom, which is dazzling, colorful and dazzling.

9. The counter shows the numbers and the students write them out.

10, mathematics has made an important contribution to the observation of nature, which explains the simplicity in the regular structure. Primitive elements, celestial bodies are made up of these primitive elements.

1 1 is related to division, multiplication, statistical knowledge, area and solving simple practical problems.

12, mathematical knowledge has three main characteristics different from other knowledge: first, mathematical knowledge makes its results more realistic than other knowledge; Secondly, mathematical knowledge is the first step to acquire other correct knowledge. Third, the acquisition of mathematical knowledge does not depend on other knowledge.

13 Mathematics is an infinite science.

14, mathematics is gymnastics to train the mind.

15, a little bit can draw countless straight lines and rays. You can only draw a straight line after two o'clock.
