The earliest known mathematics in ancient India dates back to 3000 BC with the Indus Valley civilization. After its collapse in 1700 BC however, writing was absent in South Asia for a long period. There is considerable controversy regarding the dates when writing was re-developed in India and when the Brahmi script was developed.[5] Some scholars, such as Georg Bühler, date the Brahmi script as early as the 8th century BC, others from the Maurya dynasty in the 4th century BC. Some evidence dates it to 600 BC (see Brāhmī), while some schol ...

Long before the earliest written records, there are drawings that indicate a knowledge of mathematics and of measurement of time based on the stars. For example, paleontologists have discovered ochre rocks in a cave in South Africa adorned with scratched geometric patterns dating back more than 70,000 years [1]. Also prehistoric artifacts discovered in Africa and France, dated between 35000 BC and 20000 BC, indicate early attempts to quantify time Evidence exists that early counting involved women who kept records of their monthly biological ...

The oldest mathematics text discovered so far is the Moscow papyrus, which is an Egyptian Middle Kingdom papyrus dated circa 2050 BC - 1800 BC. Like many ancient mathematical texts, it consists of what are today called "word problems" or "story problems", which were apparently intended as entertainment. One problem is considered to be of particular importance because it gives a method for finding the volume of a pyramid: "If you are told: A truncated pyramid of 6 for the vertical height by 4 on the base by 2 on the top. You are to square thi ...

The Maya calendar utilized a base-20 number system which included the 'number' zero (also see Maya numerals). In China, Zu Chongzhi (5th century) of the Southern and Northern Dynasties was the first person to calculate the value of Pi to seven decimal places.

In Europe at the dawn of the Renaissance, most of what is now called school mathematics -- addition, subtraction, multiplication, division, and geometry -- was known to educated people, though the notation was cumbersome: Roman numerals and words were used, but no symbols: no plus sign, no equal sign, no zero, and no use of x as an unknown. Almost all of the mathematics now taught in college had yet to be d ...

The History of Ireland is the story of a large island in the north-west of Europe and is heavily influenced by the concurrent History of Britain, its larger neighbour to the east. The first humans inhabited Ireland from around 7500 BC and were later responsible for major Neolithic sites such as Newgrange. Following the arrival of St. Patrick and other Christian missionaries in the mid-fifth century, a syncretized form of Christianity subsumed the indigenous pagan religion by A.D. 600. This led to a golden age of monastic Irish writing and ar ...

Baudhayana, (circa 800 BC), was a Vedic Indian learned man, likely a priest and mathematician (although not in the modern sense). He is the author of one of the earliest and most important Sulbasutras — appendices to the Vedas giving rules for the construction of altars — called the Baudhayana Sulbasutra, which contained several important mathematical results. The Baudhayana Sulbasutra contains one of the earliest references to what is known today as the Pythagorean theorem. The rope which is stretched across the diagonal of a square produces an area d ...
