what is Suanpan (Chinese Abacus)?
The Suanpan, often simply referred to as the Chinese abacus, is a traditional counting tool that has been used for centuries in
China and other East Asian countries. It is a calculating device used for performing arithmetic operations like addition, subtraction, multiplication, and division.
The Suanpan consists of a rectangular wooden frame with vertical rods or wires. Each rod represents a place value, with the rods usually divided into two sections: the upper section, where beads are placed to represent the value of five, and the lower section, where beads represent the value of one. Typically, there are two beads in the upper section and five beads in the lower section on each rod.
The Suanpan is operated by sliding beads along the rods to perform calculations. It is a versatile and efficient tool, and despite advancements in technology, it is still used in some educational settings and for mental calculation training in East Asia.
