Chinese Zhusuan, knowledge and practices of mathematical calculation through the abacus

Chinese Zhusuan is a time-honoured traditional method of performing mathematical calculations with an abacus. Practitioners can perform addition, subtraction, multiplication, division, exponential multiplication, root and more complicated equations by moving beads along the abacus rods according to defined formulas. Chinese Zhusuan has played a vital role in giving an impetus to mathematical studies, promoting algorithmic practices and fostering intelligence. Zhusuan oral formulas have easy-to-learn rhymes that represent specific calculation rules and summarize the arithmetic operations. Beginners can make quick calculations after some fairly basic training, while proficient practitioners develop an agile mind. Zhusuan is widely used in Chinese life and is an important symbol of traditional Chinese culture, providing a strong sense of cultural identity. It has been handed down through generations by Read more about this element on the UNESCO Intangible Cultural Heritage website.
