Why do you think that little is known of the early development of the decimal system?
It probably predates writing. The early development of the decimal system was done by counting on the fingers and toes.
Who took pi to the 35 decimal places?
The Dutch astronomer, Willebrord Snellius, calculated pi to 35 decimal places in the early 17th Century.
When was the current decimal system developed?
The first decimal system was introduced in the 4th Century BC by the Sumerians of Mesopotamia, to whom the invention of writing is credited. They based their numerical system on powers of 60 subdivided into multiples of 10. It was from this system that Sumero-Babylonians developed the time system that we use today: each hour is divided into 60 minutes, which are divided into 60 seconds. However, they did not have a symbol for zero, which was introduced by Arabians only toward the end of the first millennium BC. It is thought that the zero could have been devised by Indian Hindu mathematicians because the concept of nothing was important in their early religion and philosophy.
Who are the people related in the development of geometry?
The Babylonians, Egyptians, and Greeks were involved in the early development of geometry. However, the Greeks were major contributors to this field. Pythagoras, Thales, and Euclid are some men most famous for their contributions to this field.
How were numbers originated?
Well what we call 'The Natural Numbers' kind of always existed. All civilisations have had numbers and maths. What changed over the years is the representations, the Romans used roman numerals like XLCVIII, the ancient Aztecs used knots in string. The digits we use today 0,1,2 etc. are known as Arabic numerals which, confusingly, originated in India about 2300 years ago.
