Some people don't know enough about the importance of 0 and think that 0 equals' nothing'. They only knew that the Monkey King could play with a magic wand, calling it big and small, but they didn't know that zero also had such magic. As long as there is a zero standing on the right side of a positive integer, this integer can be enlarged by 10 times. For example, if a' 0' stands to the right of 4, it will immediately become 40. On the contrary, if you encounter a pure decimal, you can reduce 10 times by squeezing a zero after the decimal point, for example, squeezing a' 0' in the middle of 0.5 will become 0.05. Zero has such a great ability, how can it be said that it is equal to' no'? "If there is no 0, there is no possibility of development of mathematics. Modern electronic computers use a binary system. Among the 10 numbers from 0 to 9, all other numbers are useless, only 1 and 0 are left. This shows how important 0 is!

1, the number "0" is a magical magician who can make a number bigger and smaller. (Add a decimal point in front to change it into a decimal point, minus 10 times; Adding it to the back will enlarge it by 10 times. )

"0" itself means no, but when it is combined with other numbers, it will play a great role.

Add or subtract "0" from any number to get the same number.

Any number divided by "0" will get 0.

5. "0" cannot be divided.

6. "0" is contradictory, sometimes it means no, for example, an apple is gone after eating it; But sometimes it has a positive meaning, for example, "0 degrees Celsius" does not mean that there is no temperature, it is higher than the temperature of several degrees below zero.

7. On the number axis, the number 0, like other numbers, can also be represented by a point, and it also bears the heavy responsibility of separating positive numbers from negative numbers.

8 and 0 can also represent numbers. The 0 in the image 100 and 0.06 represents one bit, ten bits and ten bits respectively. Thus, 0 can represent not only positive numbers, but also negative numbers. The number of completed expressions also varies greatly. For example, 5,000 divided by three zeros makes 5, which is quite different.

9. When there is no previous number, 0 can also indicate a vacancy. For example, sometimes two numbers are needed to represent the month, and 65438+ October is represented by 0 1. After 0, 3 becomes 03, where 0 means vacancy. In the temperature record, 0℃ also indicates a specific temperature, and it cannot be said that there is no temperature.

10,0 is also a non-negative and non-positive neutral number, which is smaller than all positive numbers, but greater than all negative numbers, and is the dividing point of positive and negative numbers.

In the digital world, 0 also plays an important role. If 9 is 8 greater than 1, you can add 0 and decimal point before 9 to make it 0.9, but it becomes less than 1. Another example is 7 and 20. Add a 0 after 7, and 7 will be greater than 20. It can be seen that a small 0 is also very useful, which can make the number bigger and smaller.

0 is amazing, it has many important features:

One: in addition and subtraction, a number adds or subtracts 0, and the original number remains unchanged, which means no addition or subtraction, such as X+0=X and x-0 = X.

Two: in the multiplication and division method, 0 is multiplied by any number and divided by any number, and the product is 0. But 0 has another feature. 0 can't be divided, because it is mathematically considered that 0 has no meaning and can't be divided.

Therefore, 0 is still very important.
