With the abacus as a tool, mathematical algorithms as a theoretical facility, Chinese Zhusuan is figure-based knowledge and practices through moving beads on an abacus according to the defined formulas. The abacus is made of bamboo or wood in the shape of a rectangle, divided horizontally into two decks with a string of five beads (one in the upper deck and four in the lower) or a string of seven beads (two in the upper deck and five in the lower). Each bead in the upper deck has a value of 5 while each in the lower has a value of 1. Atypical abacus has 13 to 19 rods connecting the beads. Zhusuan practitioners can perform mathematical calculations including addition, subtraction, multiplication, division, exponential multiplication, root, equations of higher degree, thus demonstrating the wonderful wisdom and creativity of the Chinese people. This time-honoured tradition has played a vital role in giving impetus to mathematical studies, promoting algorithmic practices, and nourishing intelligence. Zhusuan oral formulas have easy-to-learn rhymes that represent the specific calculation rules and summarize the arithmetic operations. Beginners can make quick calculations after moderate trainings, while proficient practitioners usually develop an agile mind. Through oral teaching and bodily practice, Chinese has maintained and transmitted Zhusuan for generations. With a scientific theoretical system and a simple operation method, Zhusuan has long been popular in various aspects of Chinese living and production. As an important legacy of mathematics and cultural tradition, Zhusuan has become a national symbol of cultural identity.
