Wood Carport Builders Definition

It is difficult to determine the starting point for a historical synthesis of computing, since there are many works and discoveries that resulted in the construction of the first computers. Since time immemorial, humanity has used instruments to perform wood carport builders calculations and to store and process information. The first tool that served to count and at the same time to represent the counted quantities were the fingers, giving rise to the decimal numbering system.

Early man used pebbles to represent numbers and do simple additions. 500 years BC, the abacus was invented and reinvented by different cultures in space and time, such as the Aztecs and the Sumerians. The Russian abacus is decimal, it has ten wooden rings in each column. In Chinese the board is divided wood carport builders into two zones, "heaven" and "earth", with two and five balls respectively. On the Molecular Expressions page , an abacus is shown in which it is possible to simulate real operations.

THE ABACUS

Considered the oldest instrument of calculation, adapted and appreciated in various cultures. The origin of the abacus is literally lost in time. In very early times primitive man found materials to devise counting instruments. It is probable that its beginning was a flat surface and stones that moved on lines drawn with dust. Today there is a tendency to think that the origin of the abacus is in China, where the use of this instrument is still notable, as in Japan.

The word abacus is Latin and has its origins from the Greek abax or abakon , which means "flat surface" or "table", it is possible that it has originated from the Semitic word Abaqwhich means "dust". Other names are: the Chinese abacus is Suan Pan , the Japanese is Soroban , in Korea Tschu Pan , in Vietnam Ban Tuan or Ban Tien , in Russia Schoty , Turkey Coulba and Armenia Choreb .

Because much of the arithmetic was done on the abacus, the term abacus has become synonymous with arithmetic, and we find such a denomination in Leonardo de Pisa Fibbonacci (1170-1250) in his book "Liber Abaci" published in 1202, which deals with the use of Indo-Arabic numerals.
