Is zero a number? If so, what is its value?

In normal arithmetic operations, expressions have no meaning. Even if you multiply by 0 to obtain a (assuming a ≠ 0), dividing by zero is not defined. Since the numeric value multiplied by zero is all zero, the expression 0/0 is also undefined; in the case of the restricted form it is an undefined form.

Zero is not positive or negative. Even if zero is not a positive number, it is considered an integer.

Figure 3 is a concept that does not actually exist. It is just a language to describe the size of the actual object.

If you do not have anything, you do not have anything (real or imaginary). But zero is the value of the amount you have.

By implication that the number divided by zero is infinite, its face value appears to be correct, but zero multiplication by infinity is an arbitrary number, so all numbers are equal So it is an error. But Bhaskara discovered that the square of zero is zero, as the square root is. The Indian digital system and its position value, decimal method gained the attention of the Arabs in the 7th and 8th century and became the foundation of the famous progress of Arabic mathematics represented by al-Khwarizmi and other people. Al-Khwarizmi wrote Al'Khwarizmi in India's clearing art and explained about Indian numerical system based on numbers from 1 to 9 and 0. Scholars like Ibn Izira and al-Samawal used the concept of zero in al-Khwarizmi's work. In the 12th century, Samawar used zero extended arithmetic operations as follows.

Values ​​or numeric zeros are different from digital zero, position notation is used in digital system. Since consecutive positions of numbers have a higher weight, within the numbers skip the position using the number zero and give appropriate weights to the numbers before and after. In the position numbering system, the zero position, such as number 02, is not absolutely necessary. In some cases, you can use leading zeros to distinguish between numbers. The number 0 is the smallest nonnegative integer. The natural number after 0 is 1, and there is no natural number before 0. The number 0 can not be thought of as a natural number nor can be considered as a natural number, but since it is an integer, it is a rational number and a real number (and an algebra and a complex number).

For example, Peano's arithmetic axiom yields infinite return. Zero is a natural number, each natural number has a natural number as a successor, zero is not a successor of any natural number, and if \ (x \) and \ (y \) are natural numbers having the same successor x = y \) This creates infinite returns. There is a successor to zero. Since zero is not a successor to a natural number it can not be zero. Therefore, it must be a new natural number. People need to have successor. It can not be zeroed or it can not be made itself as in the past. Because zero and one will have the same successor at that time. So, there must be a new natural number that is the successor: 2. Both need successors. 3 persons. ... etc. This infinite return value means that there are countless things, that is, natural numbers. However, few people are concerned about this
