What does the number 0 mean and what does the number 0 mean?

0 is an integer between -1 and 1, the smallest natural number, and a rational number. 0 is neither positive nor negative, but the dividing point between positive and negative numbers. 0 has no reciprocal, the opposite of 0 is 0, the absolute value of 0 is 0, the square root of 0 is 0, the cube root of 0 is 0, 0 times any number is equal to 0, the power of 0 of any number other than 0 is equal to 0, all multiples of 0 are 0, 0 cannot be used as a divisor.

Extended Materials. One (one), ten, hundred, thousand, thousand, one thousand, million, million, million, billion, billion, billion, billion, ......, are all units of counting. The counting unit on the "single digit" is "one (one), the counting unit on the "ten" digit is "ten", and the counting unit on the "hundred" digit is "hundred".

The digits of the integer part are from the right, and every 4 digits are one level, and each level includes single digits, ten digits, hundreds of digits and thousands of digits, indicating how many ones; The 10,000 level includes 10,000, 100,000, 10,000 and 10,000,000, representing how many thousands; The 100 million level includes 100 million, 1 billion, 10 billion, and 100 billion, representing how many billions ......The decimal digits are decimal places, from left to right, they are tenths, percentiles, thousandths, ......Indicates how many tenths.

One percent.

1. One in 1,000.

0 means that there is no object. According to: "When we count objects, the number of objects used to express them is called natural numbers. There is not a single object, which is represented by 0. 0 is also a natural number. Natural numbers are all integers. ”

The implied meaning of the number 77 in Zhouyi mathematics is: half auspicious. It belongs to a half-auspicious number, and the auspicious is fierce.

The number 77 represents Qixi Festival, which is also known as Qiqiao Festival, Qijie Festival, Daughter's Day, Qiqiao Festival, Qiniang Society, Qixi Festival, Ox Bull Po Day, Qiaoxi Festival, etc., which is a traditional Chinese folk festival.

(1) Mathematical significance

0 is the smallest natural number.

0 is an even number. 0 is neither positive nor negative, but the dividing point between positive and negative numbers. is an integer between -1 and 1.

(2) Computational significance

0 times any real number is equal to 0, and dividing by any non-zero real number is equal to 0; Any real number plus or minus 0 equals itself.

There are no reciprocals and negative reciprocals for 0, and a non-0 number divided by 0 is meaningless in the range of real numbers.

(3) Implications

The number 0 is the beginning and the end. If zero is used as a number to represent auspiciousness, it is happiness and consummation, because zero is a circle, with a head and a tail, and the circle is full of good meaning.

(4) In science

In computer science, 0 is often used to represent a "false" Bollinger (Boolean) value. When a circuit transmits data, 0 and 1 represent low and high potentials, respectively. The on/off of the switch represents 0 and 1.

(5) Computer units

1 and 0 are the basic units of data processed by computers, including everything you see on the computer in 2014 is made up of two numbers, 1 and 0, each 1 or 0 is a bit, that is, one bit, and 8 bits is a byte (b).

0 is the number.

0 is an integer between -1 and 1 and is the smallest natural number.

It is also a rational number. 0 is neither positive nor negative, but the dividing point between positive and negative numbers. There is no reciprocal of 0, and the opposite of 0 is the absolute value of 0,0.

The square of 0,0 is the square root of 0,0.

is 0, the cube root of 0 is also 0, 0 times any number is equal to 0, and the power of 0 of any number except 0 is equal to 1.

B. The capitalization of 0 is: zero. Because there are many "zero" strokes, there are other ways to write it: , to indicate the empty space of the number, used in numbers, mostly used to indicate the page number or year, such as one eight pages, 199 years.

0 is an extremely important number, and the concept of 0 has been around for a long time in other regions. As early as 3000 B.C.E., the Babylonians had already learned how to use zero to avoid confusion. Ancient Egypt.

As early as the 2nd millennium B.C., there were people who used special symbols to record zeros in bookkeeping.

0 is the language used on the web to deal with homosexuality.

1.Homosexuality is an intimate relationship with the object of the same sex, or an act or phenomenon in which this sexual orientation is the main self-identification, and scientific studies have shown that homosexuality is one of the natural trends of human emotions and does not cause harm to itself. This phenomenon also exists in society now, and we should treat this phenomenon with an equal attitude.

2.Many Tanmei** also use "0" and "1" to represent homosexuality, the attacking party is called "1", and the receiving party is called "0". This language is also used to express the affection for each other, and in real life, such expressions between homosexuals need to be used with caution.

3.The digital language in the network language is mainly composed of Arabic numerals and Chinese readings, and a small amount is combined with Chinese characters or English bytes, basically a number represents a word. In Internet buzzwords, the "0" and "1" often said by netizens are not formal confessions, but just expressions of like, and there is no malice in this expression.

1. "0" can mean "no" But in addition to expressing "no", "0" has other functions:

2. Play the role of "placeholder" In counting, "0" not only means "no", but also plays the role of placeholder.

3. For example, the "0" in "906", it not only means that there is no unit on this dozens of digits, but also plays the role of occupying the number of "ten" If you do not use "0" to occupy the place, let the ten digits be empty, nine hundred and six will be written as "9 6", which will bring inconvenience to reading and calculation Another example is a car license plate number in a certain city.

It is a "000888", from which it can be seen that the city's car number is numbered with six digits, and the number of its registered and licensed cars is at most six digits, and it will not exceed 1 million The "0" in "000888" also plays a placeholder role

0, which usually means nothing. But in reality, the meaning of the zero representation is very rich.

0 can not only mean no, but also can mean yes. Radio and television report that the temperature is 0, which does not mean that there is no temperature, but it is equivalent to 32 degrees on Fahrenheit, which is also the temperature of freezing. 0 can also indicate the starting point, such as when launching a missile

9, 8, 7, 6, 5, 4, 3, 2, 1, 0 - launch". 0 is the origin point on the number line, which is also the meaning of the starting point. 0 can also indicate accuracy.

For example, in approximate calculations, the degree of accuracy is different from that of representation.

In real numbers, 0 is the only neutral number between positive and negative numbers, and has the following arithmetic properties:

a+0=0+a=a.

a-0=0×a=a×0=0，y0÷a=0，(a≠0)

0 cannot be divided, and 0 has no reciprocal;

Both the absolute value and the opposite number of 0 are 0;

The addition and multiplication of any number of zeros is equal to 0.

In exponential and factorial operations, there are: a°=1 (where a≠0), 0!=1。

0 is the only complex number where the spoke angle is not defined. 0 is not yet logarithmic. In the binary used in modern electronic computers, 0 is still a basic number.

Before the invention of zero, our ancestors' method of counting was cumbersome and imperfect, and to remember a large number, certain symbols had to be rewritten many times. When the Indian Arabic numeral was used instead of the symbol 0, the sum of the numbers 1 million, 30,000, 400, and 5 was expressed as 1345, which would have been misunderstood, either 1,030,400 or 1,345.

Therefore, the method of playing the grid is used to distinguish, and the empty place indicates the empty space. But this again makes the operation cumbersome. With 0, it can be succinctly written:

1030405。Therefore, it can be said that notation is incomplete without the adoption of 0.

0 is one of the most useful symbols in mathematics, but its invention was hard-won. Ancient Egypt built magnificent pyramids, but it did not use 0; The Babylonians invented cuneiform and would not have used 0; In ancient China, when using chips to calculate, they were afraid of making mistakes in positioning, so they began to use to represent empty spaces, and gradually wrote for the convenience of writing. The Greeks in the 2nd century AD used in astronomy to denote vacant seats, but it was not universal.

It is more generally accepted that the Indians were the first to use black dots (·) in the 6th century AD It means zero, which gradually becomes 0.
