a For sure it is not known exactly when was the invention of this system, but presumably it was between the ages II and VI D. C, but it was not until the twelfth century that were introduced in Europe and from there came to the Arab mathematicians who were those who came to preserve, collect and pass a knowledge which were the real authors. The essential part of this work were performed collection in Baghdad from 762 D. C, one of the most famous Arab mathematics is due to Al-Khwarizmi, librarian of the Caliph Al-Mamum. Al-Khwarizmi wrote a mathematical treatise which used the Hindu numbers. This treatise was translated into Latin by Adelard of Bath scholastic philosopher who made numerous trips in the Arab world. It is from the twelfth century, when some Christians began to use mathematical this numbering system, which they called Arabic numerals.
This system had serious difficulties in the beginning to prevail and it is only the fifteenth century when it became general. to the emergence of Arabic numbers and the invention of paper (which soon replaced the use of papyrus) contributed significantly to the demise of the use of Abaco in Europe. a 1. Three logarithms, slide rules a The development of mathematics, navigation and progress of science during the seventeenth century boosted the creation of new and ever-improving computing machines. Tables were needed to secure the trigonometric functions to calculate the position of the vessels, it was also necessary to reduce errors as each day trade was increasing.
