Some important discoveries occurred during the Han Dynasty. The invention of paper took place in 105 CE, by Cai Lung. The discovery of silk then lead to the creation of the Silk Road . The Silk Route created more than one way for the traders to traverse the mountains. In the Han Dynasty, numbers were developed into a system and used on a counting board and a set of counting rods called chousuan. The best known of these counting boards is the Abacus developed around the 15th Century . An abacus is a mechanical counting device consisting of a frame holding a series of parallel rods on each of which beads are strung. {Link without Title} The Chinese were so clever constructing this that you would be able to let each bead represent a counting unit, and each rod a place value. The primary purpose of the abacus was not to perform actual computations, but to provide a quick means of storing numbers during a calculation. The ''Chou-pei'' is the oldest Chinese mathematical text authored around 300 BC. The ''Chiu chang suan shu'' is the most famous Chinese math book. It contains all the mathematical knowledge in China up to the middle of the 3rd Century . It is a collection of 246 problems. It consists of nine chapters; land surveying, millet and rice, distribution by progression, diminishing breadths, engineering works, taxation, rule of false position, calculating by tabulation, and right triangles. {Link without Title} SEE ALSO REFERENCES {Link without Title} Weisstein, Eric.
