Extractions: The above picture is my favourite proof of Pythagoras' theorem. Filling in the details is left as an exercise to the reader. A detailed version of the proof, for those who do not feel up to the challenge, appears in Alan M. Selby 's Appetizers and Lessons for Math and Reason (although he only uses the righthand picture with algebra, not geometry, to prove the required identity). This proof is sometimes referred to as the Chinese square proof , or just the Chinese proof . It is supposed to have appeared in the Chou pei suan ching (ca. 1100 B.C.E.), according to Ralph H. Abraham [see ``Dead links'' below,] who attributes this information to the book by Frank J. Swetz and T. I. Kao, Was Pythagoras Chinese? . See also Development of Mathematics in Ancient China According to David E. Joyce 's A brief outline of the history of Chinese mathematics , however, the earliest known proof of Pythagoras is given by Zhoubi suanjing (The Arithmetical Classic of the Gnomon and the Circular Paths of Heaven) (c. 100 B.C.E.-c. 100 C.E.)

http://www.sienahts.edu/~adebner/mathstuff/arith.htm

Extractions: Amy Debner Toni Carroll There are several ideas and people that played a major role in developing arithmetic operations through the early history. Treviso Arithmetic was the earliest known printed arithmetic book. It appeared, in 1478, even before the printed edition of Euclids Elements The original book was written in Venetian dialect, had no formal title, and it has an unknown author. The reason it is named Treviso Arithmetic is because Treviso is where the book originated. The great thing about this mathematics book was that it was aimed at a broad audience and it was intended for individual study. Treviso Arithmetic was a very practical book because Venice and Treviso were major trading centers during the 15 th Century. The books language, examples, and problems reflected a wide range of commercial concerns (Peterson, 1996). And it contained all that was known in that day of arithmetic, algebra, and trigonometry (Struik, 1967). Treviso Arithmetic introduced a new math, promoting the use of Hindu-Arabic numeral system and the pen-and-ink computational algorithms that accompanied this notion (Peterson, 1996). This is a problem that appeared in the Treviso Arithmetic textbook: Three merchants have invested their money in a partnership.

Extractions: Math 309 April 2001 The basis and inspiration for the whole of Indian mathematics is geometry. The beginnings of algebra can be traced to the constructional geometry of the Vedic priests preserved in the Sulbasutras , a manual of geometrical constructions from the 5 th to the 8 th centuries. Earlier remnants of geometrical knowledge of the Indus Valley Civilisation can be found in excavations at Harappa and Mohenjo-daro where there is evidence of circle-drawing instruments from as early as 2500 B.C.E. (Amma 1) Early geometry of the Sulbasutras was based on religious needs with regards to the construction of altars such as agnicitis, vedis, mandapas etc. that are required for sacrificial ritual (Kulkarni 19, Amma 3). The history of Indian geometry can be divided into three distinct periods: pre-Aryan, such as excavated in Indus Valley. Vedic or Sulbasutra post-Christian. Evidence of the pre-Aryan period includes well-planned towns and geometric designs including circles, squares and triangles. A link between this and the Vedic period can be found in the motif of a rectangle with the four sides curved inwards resembling a stretched hide; in the former period it can be seen as a decorative pattern while in the later period it is seen in the shape of the sacrificial altars or vedi . The vedi as well as the fireplaces or agni had such exact measurements and geometric shapes that they were codified and became the Sulbasutras . However, it is not known from how far back such knowledge originated as the sacrificial act is as old as the Vedas or older (Amma 5).

This type of equations was first solved by Brahmagupta and BhaskaraII. Later, bhaskara ii (AD 12th century) simplified this method.

Extractions: the remaining people ate for $41 each. Basically, you want me to solve the equation in integers . Look at that equation. 12n is divisible by 3, 9 is divisible 3, so 41m also must be divisible by 3, which means m is divisible by 3. Putting m = 3k, we get a simpler equation Such equations are called indeterminate or Diophantine equations and there are many methods to solve them. I give two of them. Correct Answer was sent by : Balaji R, CA, USA I am using the symbol == to denote "is congruent to" as there is no symbol for congruence in standard ASCII set. So, 41k == 3 (mod 4) 4n == 3 (mod 41) Since 41 and 4 are mutually prime, this is soluble by considering the complete residue system. Thus, by putting k = 0, 1, 2, 3, we get 41k is congruent to 0, 1, 2, 3 respectively (mod 4). . So k = 3 is a solution to the congruence 41k == 3 (mod 4). So k = 3 , which means n and m To solve Express (41/4) as a continued fraction in such a way that there are an odd number of terms in the expansion. Now, leave the last term and evaluate the fraction. Let it be (a/b). Now 41b - 4a = 1. Multiplying all the terms of the equation by 3, we get the solution to 41k - 4n = 3. The continued fraction expansion of (41/4) is 10 + (1/4), giving the values (10/1) and (41/4). The penultimate fraction is (10/1). So 41.1 - 4.10 = 1. Multiplying it by 3, we get 41.3 - 4.30 = 3.

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.
