Understanding of primary school stage 0

First of all, understand the three meanings of 0 and "0"

1 and "0" are the marks of an empty set, which can be used to indicate that there are no elements in the set, for example, there is no candy on the far right in the picture. Generally speaking, you can use 0 to indicate no, then, that is to say, 0 is also a number like 1 and 2. If there is no, you can use 0.

2. Represents a starting point or origin, such as the origin on a number axis or coordinate.

That is to say, 0 is used to indicate the starting point, such as the scale on a ruler, the scale on a thermometer and so on. When measuring the length of a thing, count from 0, where 0 represents the starting point.

3. Indicates space occupation, such as counting, scoreboard, house number, etc. Represents a number, such as (10,20).

To sum up, in the first grade of primary school, the three most common meanings of "0" are: one for no, two for starting point (start) and three for points.

Second, writing about 0:

1. Take a closer look and tell me what 0 looks like. -Is it particularly like an egg you often eat?

2. When writing, you must pay attention to the order of strokes: from the top right corner, from top to bottom, from left to right, writing is relatively smooth. Don't write circles, points or angles.

3. About the teaching of 0 addition and subtraction: "There are 3 birds in the nest, all of which have flown away, and there are still 0 birds. 3-3=0 ""There are 4 frogs on the left and 0 frogs on the right. A * * *, how many frogs are there? " ? Formula: 4+0=4. Try it: What is "4-0"? what do you think?

Third, summary:

Summarize the characteristics of the formula with 0:

1, a number minus itself equals 0;

2. Any number of plus or minus 0 is equal to this number.

Understanding of 0

0' has different meanings.

In traditional science, "0" is generally understood as "nothing", that is, "nothing"; Understand "1" as yes.

In fact, what needs to be pointed out in particular is that from the outside of "0", "0" does mean "nothing"; But from the inside of "0", "0" contains everything in the universe and represents all "existence".

For example, (+1)+(- 1)=0,

(+i)+(-i)=0，

(+N)+(-N)=0 .

The sum of all positive and negative values with the same size is 0, which means that the inside of 0 contains all positive and negative numbers, and no number is missing!

"0" is the sum of all numbers, so from the inside of "0", 0 contains all numbers, which means all "yes".

Externally, "0" is "none"; Internally, "0" is "Yes". Obviously "0" is the boundary between "yes" and "no".

Outside of "0" is traditional science, and inside of "0" is the mathematical principle of natural universe. Obviously, "0" is also the boundary between traditional science and the mathematical principle of the natural universe.

For the mathematical principle of the natural universe, it mainly studies the interior of "0".

It should be recognized that "0" contains a large number. If each number is regarded as a part, there are infinite parts in "0", and all the infinite parts add up to "0". "0" is the concept of the largest category, and the category without concept is greater than "0".

"0" is all of all "numbers" and is the most complete "number". Other numbers are only a small part of "0", all fragments of "0", all incomplete and incomplete. So all other "numbers" are incomplete and imperfect, and only "0" is the most perfect.

Because "0" contains all the numbers, it is the group with the largest number. There are infinite individuals in the group, and each individual is a number.

Modern science uses numbers to describe things. If everything in the universe is described by numbers, it becomes a digital universe. Describing the universe with mathematics is a research method of modern science.

If everything in the universe is put together, it is the whole universe, so this operation is to put all the "numbers" representing everything in the universe together, and the sum of all the "numbers" together is "0".

Obviously, the universe as a whole corresponds to the number "0", and everything in the universe corresponds to other "numbers" respectively.
