What is decimal system?

What Does decimal system Mean

The decimal system is a numbering system : a series of symbols that, respecting different rules , are used to construct the numbers that are considered valid. In this case, the system is based on ten .

This means that the decimal system is responsible for the representation of quantities using ten different figures or digits: 0 (zero), 1 (one), 2 (two), 3 (three), 4 (four), 5 (five ), 6 (six), 7 (seven), 8 (eight), and 9 (nine).

It is important to note that the decimal system is a positional system . The digits acquire their value according to the relative position they occupy. This position, in turn, depends on the base in question.
The decimal system, as we said, appeals to ten digits and has the powers of the number ten as its base. Thus: 10 raised to 0 equals 1 ; 10 to the power of 1 equals 10 ; 10 to the power of 2 equals 100 ; etc.
Diverse and varied are the curiosities that are worth knowing about the aforementioned decimal system. However, among them are, for example, the following:

-It is considered that it was an invention of the Hindus and that the Arabs came to European territory.

-Historians and other experts in the field coincide in emphasizing that possibly the fact that it is a system based on 10 is due to the ten fingers that we have between both hands and that, over time, man has used to tell.

-With regard to the decimal separator caller, there are basically three options: the comma, the period and the high point. In Spain, for example, it is preferred to use the comma while in the United States the point is more preferred.

-As we have mentioned previously, the groupings that it has are formed from 10 to 10, which results in their existing, within what are the units, for example, both the units themselves and the tens or hundreds.
The number 523 , for example, has three digits. In the decimal system, it is constructed as follows, respecting the corresponding positions :
(5 x 10 to the power of 2) + (2 x 10 to the power of 1) + (3 x 10 to the power of 0)
(5 x 100) + (2 x 10) + (3 x 1)
500 + 20 + 3
523
As can be seen, from right to left, the first place corresponds to the unit ( 10 raised to 0 ), the second place corresponds to the ten ( 10 raised to 1 ) and the third place corresponds to the hundred ( 10 raised to 2 ).
In addition to all the above, we have to underline the value of what has become known as the Dewey decimal classification system (CDD) that is used in libraries. It was created at the end of the 19th century, specifically in 1876, in the United States and is identified because the publications are classified into ten different categories:

-Generalities.

-Philosophy and Psychology.

-Religion and Theology.

-Social Sciences.

-Languages.

-Basic sciences.

-Technology and Applied Sciences.

-Arts and recreation.

-Literature.

-History and geography.
