Alexander Wylie, Christian missionary to China, in 1853 already refuted the notion that "the Chinese numbers were written in words at length", and stated that in ancient China, calculation was carried out by means of counting rods, and "the written character is evidently a rude presentation of these". After being introduced to the rod numerals ...
Counting rods (筭) are small bars, typically 3–14 cm (1" to 6") long, that were used by mathematicians for calculation in ancient East Asia.They are placed either horizontally or vertically to represent any integer or rational number.
For number between 6 and 9, a biquinary system is used, in which a horizontal bar on top of the vertical bars represent 5. The first row are the number 1 to 9 in rod numerals, and the second row is the same numbers in horizontal form. For numbers larger than 9, a decimal system is used. Rods placed one place to the left of the units place ...
Number systems have progressed from the use of fingers and tally marks, perhaps more than 40,000 years ago, to the use of sets of glyphs able to represent any conceivable number efficiently. The earliest known unambiguous notations for numbers emerged in Mesopotamia about 5000 or 6000 years ago.
The Book on Numbers and Computation (Chinese: 筭數書; pinyin: Suàn shù shū), or the Writings on Reckoning, [1] is one of the earliest known Chinese mathematical treatises. It was written during the early Western Han dynasty , sometime between 202 BC and 186 BC. [ 2 ]
The Suzhou numerals, also known as Sūzhōu mǎzi (蘇州碼子), is a numeral system used in China before the introduction of Hindu numerals.The Suzhou numerals are also known as Soochow numerals, [1] ma‑tzu, [2] huāmǎ (花碼), [3] [better source needed] cǎomǎ (草碼), [3] [better source needed] jīngzǐmǎ (菁仔碼), [3] [better source needed] fānzǐmǎ (番仔碼) [3] [better ...
Mathematics emerged independently in China by the 11th century BCE. [1] The Chinese independently developed a real number system that includes significantly large and negative numbers, more than one numeral system (binary and decimal), algebra, geometry, number theory and trigonometry.
The numbers 0–9 in Chinese huama (花碼) numerals. The ancient Chinese used numerals that look much like the tally system. [27] Numbers one through four were horizontal lines. Five was an X between two horizontal lines; it looked almost exactly the same as the Roman numeral for ten.
