    Extractions: Sridhara is now believed to have lived in the ninth and tenth centuries. However, there has been much dispute over his date and in different works the dates of the life of Sridhara have been placed from the seventh century to the eleventh century. The best present estimate is that he wrote around 900 AD, a date which is deduced from seeing which other pieces of mathematics he was familiar with and also seeing which later mathematicians were familiar with his work. We do know that Sridhara was a Hindu but little else is known. Two theories exist concerning his birthplace which are far apart. Some historians give Bengal as the place of his birth while other historians believe that Sridhara was born in southern India. Sridhara is known as the author of two mathematical treatises, namely the Trisatika (sometimes called the Patiganitasara ) and the Patiganita.

    Extractions: Mathematics science of spatial and numerical relationships. The main divisions of pure mathematics include geometry, arithmetic, algebra, calculus, and trigonometry. Applied mathematics include statistics , numerical analysis, computing, mathematical theories of astronomy , electricity, optics, thermodynamics, and atomic studies. Prehistoric human beings probably learned to count at least up to ten on their fingers. The Chinese, Hindus, Babylonians and Egyptians all devised methods of counting and measuring that were of practical importance in their everyday lives. The first theoretical mathematician is believed to be Thales of Miletus (580 BC) who is believed to have proposed the first theorems in plane geometry. His disciple Pythagoras established geometry as a recognised science among the Greek. The later School of Alexander Geometers (4th and 3rd centuries BC) included Euclid and Archimedes. The present decimal numbers are based on a Hindu-Arabic system that reached Europe about AD 100 from Arab mathematicians of the Middle East such as Khwarizmi. The basic development of mathematics in India (including Bengal) took place between 500 BC and 500 AD, marked as Buddhist and Jaina period. Mathematics in Buddhist and Jaina period The topics of mathematics, according to the Sthananga-sutra (sutra 747) are ten in numbers: parikarma (four fundamental operations), vyavahara (subjects of treatment), rajju (geometry), rashi (mensuration of solid bodies), kalasavarna (fractions), yavat-tavat (simple equation), varga (quadratic equation), ghana (cubic equation), varga-varga (biquadratic equation) and vikalpa (permutation and combination). However, the historians of mathematics differ in explaining some of the terms from the commentator, Abhayadeva Suri (1050 AD).

    Extractions: 1101 to 1200 Setting the scene Islamic culture is the most advanced in the western world. Many scientific and mathematical terms (eg "algebra" and "algorithm") are of Arabic origin, reflecting their roots in these early days of recorded science. The Islamic empire is vast, and much of its success is down to trade and commerce. Many countries become part of the Islamic empire and many others trade with it, so there is an input to scientific ideas from many different cultures including Iran, Turkey, India and China. The Arabic language becomes a unifying factor allowing ideas to be exchanged freely, and centres of learning and wisdom arise in a number of places, including Baghdad, Al-Ma'mum and Cordoba in Spain. Many areas of science and mathematics move forward during these years. Increasingly accurate astronomical observations are made, and mathematics benefits enormously from the introduction of Indian numerals - referred to today as Arabic numerals. With these numerals great strides are made in solving equations (algebra), trigonometry and numerical calculations. Chemistry becomes an experimental subject at last, as does physics. And health care is comprehensive, with doctors, hospitals and even special care for the mentally ill.

    Extractions: International Study Group on the Relations Between HISTORY and PEDAGOGY of MATHEMATICS NEWSLETTER No. 46, March 2001 An Affiliate of the International Commission on Mathematical Instruction History makes a man wise is a common saying. By studying history we can know the errors and mistakes committed in the past and save ourselves from repeating them. According to P. S. Jones "One use of the history of mathematics is to reveal to students come of the conceptual difficulties and errors which have impeded progress". G. A. Miller even says "The teachers of mathematics may frequently gain more from a clear exposition of failures than from such an exposition of successes on the part of the eminent mathematicians of the past". In this brief note we mention the mistakes, gathered from a few earlier works, in connection with some arithmetical operations involving the number zero (now denoted by the hole "0"). 1. The great Indian mathematician Brahmagupta (7th century AD) was the first to give explicitly in his Brahmasphuta-Siddhanta (chapter XVIII), the various rules involving zero (in arithmetical operations) but they also include his statement that "zero divided by zero is zero". That is, ÷ = which is not true in general.
