There is even the science about the magical essence of numbers and their possibilities to influence the world. It is called numerology. Nowadays this is one of the most developed spheres of magic studying.

Pifagor is the father of numerology who was the first to recognise the importance of numerals. He developed philosophy according to which the whole world was built on numerals.

According to numerologists every number corresponds to the planet. In fact numerology was always connected with astrology. Since Pifagor times these numbers and planets that correspond to people can tell a lot about their personalities.

Arabic numerals

Arabic numerals are the traditional name of the number of numerals that consists of ten figures that are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 that are used nowadays in the majority of countries in the decimal notation.

The Arabic numeral appeared in India not later than in the 5th century. At that time the figure "0" was discovered and it got its form. In such way the invention of zero allowed to get to the positional writing of numerals.

The traditional Arabic numerals are the changed figures of Indian numerals that were adapted to the Arabic writing. The Indian system of numerals writing was made popular by the Arab scientist that in fact invented the term "algebra".

Europeans got to know about Arabic numerals in the 10-13th centuries thanks to their images on the counting beads of abacus that were drawn sideway to save the space.

The name "Arabic numerals" was formed historically because Europeans got to know about the decimal notation thanks to Arabs. Numerals that are used in the Arabic countries differ a lot from the numerals that we use. They are written practically in another way and have different form.

There are also systems of writing the numerals with the help of the language resources. The figure "0" was not invented at first. People didn't have and use it at all. But with time they realised the necessity in this numeral. And the Arabic name of zero gave the denomination of the word "number" to many languages of the world.
