# Influence of Greek and Indian mathematics on Muslim scholars

Kay Lewis & Aleisha Campbell

#### Transcript of Influence of Greek and Indian mathematics on Muslim scholars

When the astrolabe was invented c. 220 CE it was a simple tool that was used to tell basic directions. It was an ancient compass that allowed the sailors of the time to keep track of which direction they were heading in. The Muslim Astrolabe Muslim Number System Algebra The form of algebra that was practiced within the Greek society in was geometrical. Any solution that included an irrational number was expressed by a shape due to the fact that Greek scholars neglected negative and irrational numbers. Therefore their solutions were approximations and were never completely accurate. Continuity & Change Over Time By: Kay Lewis & Aleisha Campbell Influence of Greek and Indian Mathematics on Muslim scholars The Indian number system was the first to introduce the place holder of zero. All the number systems before neglected a number before one and had decimals as a place holder. Indian scholars traveled to Arabia and they explained the concept of zero to Muslims scholars. The scholars then applied the number zero to their rewritten number system, that was used as the basis of arithmetic. The Muslim scholars were able to evaluate any equation and express any number. Upon being introduced to the Muslims in the 9th century CE, the astrolabe evolved into an instrument that had the capability of telling the time of day. The Muslims gained this technology through the translation of Greek texts that had arrived in the Arabian Peninsula by merchants. The astrolabe allowed the Muslims to determine the direction of Mecca which was essential to their region. It also furthered their interests into astrology, they began to chart the stars and create theories of planets. These advances were only possible through the diffusion of these two regions, this addition to prior knowledge is a prime example of collective learning. Diffusion between the Indians and the Muslims created a number system that allowed a more practical way to asses multiplication and division problems. The number system also made it possible for fractions to be included into problems and for the problems to be evaluated accurately. Mathematical findings that were recorded in Alexandria, Egypt during its allegiance to Greece became apart of the Muslim library when the region was absorbed by the Umayyads. The dynasty extended their control into Africa and gained access to the knowledge that included the basis of today's physics, chemistry and findings in terms of astrology. These books were translated and applied to the Arabic methods, the Muslim scholars combined the new knowledge with the old knowledge to create Algebra and other mathematical processes. When the Muslims were introduced to the concept of algebra in the 7th century, they transformed it into a rhetorical form. They were able to calculate quadratic equations and express their irrational solutions very accurately. Despite this major advancement in the world of mathematics, they continued to neglect negative numbers.
