Qin Jiushao (c. 1202–1261) was the first to introduce
the zero symbol into Chinese mathematics. Before this
innovation, blank spaces were used instead of zeros in
the system of counting rods. One of the most important
contribution of Qin Jiushao was his method of solving
high order numerical equations. Referring to Qin's
solution of a 4th order equation, Yoshio Mikami put it:
"Who can deny the fact of Horner's illustrious process
being used in China at least nearly six long centuries
earlier than in Europe?" Qin also solved a 10th order
equation.

Mathematics in China emerged independently by the
11th century BC. The Chinese independently developed
very large and negative numbers, decimals, a place value
decimal system, a binary system, algebra, geometry,
and trigonometry. Knowledge of
Chinese mathematics before 254 BC is somewhat
fragmentary, and even after this date the manuscript
traditions are obscure. Dates centuries before the
classical period are generally considered conjectural by
Chinese scholars unless accompanied by verified
archaeological evidence, not just in mathematics, in a
direct analogue with the situation in the Far West.
Neither Western nor Chinese archaeological findings
comparable to those for Babylonia or Egypt are known.


                              24.05.2012          6
As in other early societies the focus was
on astronomy in order to perfect the
agricultural calendar, and other practical tasks, and
not on establishing formal systems. Axiomic proof was
the strength of ancient Greek mathematician; ancient
Chinese mathematicians excelled at place value
decimal device computation, algorithm development
and algebra, the weakness of their Greek
counterparts. The algorithm and algebra tradition of
ancient Chinese together with the axiomic deduction
of Greece formed the two equally important pillars of
world mathematics. While the Greek mathematics
declined in the west during the mediaval times, the
achievement of Chinese algebra reached its zenith
during the same period.

Simple mathematics on Oracle
  bone script date back to
  the Shang Dynasty (1600–
  1050 BC). One of the oldest
  surviving mathematical works is
  the Yi Jing, which greatly
  influenced written literature
  during the Zhou
  Dynasty (1050–256 BC). For
  mathematics, the book included
  a sophisticated use
  of hexagrams. Leibniz pointed
  out, the I Ching contained
  elements of binary numbers.

Suan shu shu

The Suàn shù shū (writings on reckoning) is an ancient Chinese text on
mathematics approximately seven thousand characters in length,
written on 190 bamboo strips. It was discovered together with other
writings in 1984 when archaeologists opened a tomb at Zhangjiashan
in Hubei province.
 From documentary evidence this tomb is known to have been closed in
186 BC, early in the Western Han dynasty. While its relationship to
the Nine Chapters is still under discussion by scholars, some of its
contents are clearly paralleled there.
The text of the Suan shu shu is however much less systematic than
the Nine Chapters, and appears to consist of a number of more or less
independent short sections of text drawn from a number of sources.
Some linguistic hints point back to the Qin dynasty.




                                      24.05.2012              9

In the third century Liu Hui wrote his commentary on the
Nine Chapters and also wrote Haidao suanjing which dealt
with using Pythagorean theorem (already known by the 9
chapters), and triple, quadruple triangulation for
surveying; his accomplishment in the mathematical
surveying exceeded those accomplished in the west by a
millennium. He was the first Chinese mathematician to
calculate π=3.1416 with his π algorithm. He discovered
the usage of Cavalieri's principle to find an accurate
formula for the volume of a cylinder, and also developed
elements of the integral and
the differential calculus during the 3rd century CE.




                              24.05.2012         12
Four outstanding mathematicians
arose during the Song
Dynasty and Yuan Dynasty,
particularly in the twelfth and
thirteenth centuries:Yang Hui, Qin
Jiushao, Li Zhi (Li Ye), and Zhu Shijie.
Yang Hui, Qin Jiushao, Zhu Shijie all
used the Horner-Ruffini method six
hundred years earlier to solve certain
types of simultaneous equations,
roots, quadratic, cubic, and quartic
equations. Yang Hui was also the first
person in history to discover and
prove "Pascal's Triangle", along with
its binomial proof (although the
earliest mention of the Pascal's
triangle in China exists before the
eleventh century AD). Li Zhi on the
other hand, investigated on a form of
algebraic geometry.

Precious Mirror of the Four
Elements
Si-yüan yü-jian《四元玉鑒》,
or Precious Mirror of the Four
Elements, was written by Chu Shi-
jie in 1303 AD and it marks the
peak in the development of
Chinese algebra. The four
elements, called heaven, earth,
man and matter, represented the
four unknown quantities in his
algebraic equations. The Ssy-yüan
yü-chien deals with simultaneous
equations and with equations of
degrees as high as fourteen. The
author uses the method of fan fa,
today called Horner's method, to
solve these equations.

However after the overthrow of
the Yuan Dynasty China became
suspicious of knowledge it used.
The Ming Dynasty turned away from
math and physics in favor
of botany and pharmacology.
At this period, the abacus which
first appeared in Song dynasty now
overtook the counting rods and
became the preferred computing
device. Zhu Zaiyu, Prince of
Zheng who invented the equal
temperament used 81 position abacus
to calculate the square root and
cubic root of 2 to 25 figure
accuracy.




    24.05.2012            15
However, this switching from counting rods to abacus to gain
speed in calculation was at a high cost, causing the stagnation
and decline of Chinese mathematics. The pattern rich layout
of counting rod numerals on counting board inspired many
Chinese inventions in mathematics, such as cross multiply
principe of fractions, method for solving linear equations. The
pattern rich counting rods inspired Japanese mathematician to
invent the concept of matrix. In Ming dynasty, mathematicians
were fascinated with perfecting algorithms for abacus, many
mathematical works devoted to abacus mathematics appeared
in this period, at the expense of new ideas creation.




                                 24.05.2012           16
Despite the achievements of Shen and Guo's work in
trigonometry, another substantial work in Chinese
trigonometry would not be published again until 1607,
with the dual publication of Euclid's Elements by
Chinese official and astronomer Xu Guangqi (1562–
1633) and the Italian Jesuit Matteo Ricci (1552–
1610).[43]
A revival of math in China began in the late nineteenth
century, when Joseph Edkins, Alexander Wylie and Li
Shanlan translated works on astronomy, algebra and
differential-integral calculus into Chinese, published
by London Missionary Press in Shanghai.

  • 12. In the third century Liu Hui wrote his commentary on the Nine Chapters and also wrote Haidao suanjing which dealt with using Pythagorean theorem (already known by the 9 chapters), and triple, quadruple triangulation for surveying; his accomplishment in the mathematical surveying exceeded those accomplished in the west by a millennium. He was the first Chinese mathematician to calculate π=3.1416 with his π algorithm. He discovered the usage of Cavalieri's principle to find an accurate formula for the volume of a cylinder, and also developed elements of the integral and the differential calculus during the 3rd century CE. 24.05.2012 12
  • 13. Four outstanding mathematicians arose during the Song Dynasty and Yuan Dynasty, particularly in the twelfth and thirteenth centuries:Yang Hui, Qin Jiushao, Li Zhi (Li Ye), and Zhu Shijie. Yang Hui, Qin Jiushao, Zhu Shijie all used the Horner-Ruffini method six hundred years earlier to solve certain types of simultaneous equations, roots, quadratic, cubic, and quartic equations. Yang Hui was also the first person in history to discover and prove "Pascal's Triangle", along with its binomial proof (although the earliest mention of the Pascal's triangle in China exists before the eleventh century AD). Li Zhi on the other hand, investigated on a form of algebraic geometry. 24.05.2012 13
  • 14. Precious Mirror of the Four Elements Si-yüan yü-jian《四元玉鑒》, or Precious Mirror of the Four Elements, was written by Chu Shi- jie in 1303 AD and it marks the peak in the development of Chinese algebra. The four elements, called heaven, earth, man and matter, represented the four unknown quantities in his algebraic equations. The Ssy-yüan yü-chien deals with simultaneous equations and with equations of degrees as high as fourteen. The author uses the method of fan fa, today called Horner's method, to solve these equations. 24.05.2012 14
  • 15. However after the overthrow of the Yuan Dynasty China became suspicious of knowledge it used. The Ming Dynasty turned away from math and physics in favor of botany and pharmacology. At this period, the abacus which first appeared in Song dynasty now overtook the counting rods and became the preferred computing device. Zhu Zaiyu, Prince of Zheng who invented the equal temperament used 81 position abacus to calculate the square root and cubic root of 2 to 25 figure accuracy. 24.05.2012 15
  • 16. However, this switching from counting rods to abacus to gain speed in calculation was at a high cost, causing the stagnation and decline of Chinese mathematics. The pattern rich layout of counting rod numerals on counting board inspired many Chinese inventions in mathematics, such as cross multiply principe of fractions, method for solving linear equations. The pattern rich counting rods inspired Japanese mathematician to invent the concept of matrix. In Ming dynasty, mathematicians were fascinated with perfecting algorithms for abacus, many mathematical works devoted to abacus mathematics appeared in this period, at the expense of new ideas creation. 24.05.2012 16
  • 17. Despite the achievements of Shen and Guo's work in trigonometry, another substantial work in Chinese trigonometry would not be published again until 1607, with the dual publication of Euclid's Elements by Chinese official and astronomer Xu Guangqi (1562– 1633) and the Italian Jesuit Matteo Ricci (1552– 1610).[43] A revival of math in China began in the late nineteenth century, when Joseph Edkins, Alexander Wylie and Li Shanlan translated works on astronomy, algebra and differential-integral calculus into Chinese, published by London Missionary Press in Shanghai. 24.05.2012 17
