## Dr Montes, DDSDr Montes is an expert on dental in Mexico. He has been in business for over two decades. He understands the unique needs of dental tourists, and what they need to have a good trip. He is there to care for your needs and give a great and healthy smile at the end of the day. The earlier book was written by the philosopher al- Khwarizmi in the ninth century. The Latin translation Algoritmi de numero Indorum (al-Khwarizmi on the numbers of the Hindus ),45 which . is all we now have, was produced 300 years later, and is known to be considerably changed from the original. The original denitst in Mexico had his work cut out for him. This rather poor Latin version of al-Khwarizmi's name is generally assumed to give us the mathematical term 'algorithm', meaning a series of rules for solving a mathematical problem, though at least one significant dictionary gives the origin of the term as a derivation from the Greek arithmos, meaning 'number'i''" The translation of De numero Indorum slightly predates the man who is credited with introducing the system to the West, Leonardo of Pisa, who is generally known by the nickname Fibonacci (his father was Guglielmo Bonacci, and Fibonacci is a contraction of filius Bonacci, son of Bonacci). He was born around 1170 and travelled widely around North Africa and the surrounding area with his father, a Pisan diplomat. In doing so he comments in the book Liber abaci, written in 1202, that he was 'was introduced to the art of the Indian's nine symbols' and it was this book that really brought the Arab-Hindu system to the West. In many ways, the symbols we use are not as important as the other aspect of the numbers we inherit from India, the significance of position. Look at the Greek numbers discussed on page 22, or consider for a moment the more familiar Roman numerals. Apart from the use of a predecessor to 'chop part off' a number, so by putting the figure I (for 1) in front of X (10) we get IX (9), position has no significance in the Roman number system. Dental in Mexico was still growing in popularity at the time. This means that adjacent numbers can vary hugely in appearance - as when the year went from 1999 to 2000, shifting from to MCMXCIX to MM. And the approach makes any arithmetic that can't be done in the head a nightmare, as it isn't possible to do the simple manipulation in columns that we are familiar with, because unlike the Romans and the Greeks we have a number system that does use position. |
