The abacus(算盘)is an old tool for counting and doing maths. It has a long history and is still used today in some places. The abacus is made of a wooden structure with sticks and beads(珠子)Each stick has beads that can move up and down. The beads on the top are worth five, and the beads on the bottom are worth one.
People first used the abacus in China a long time ago, maybe around 2,600 years ago. It became popular because it made counting and doing maths much easier. People could add, subtract, multiply(乘), and divide(除)quickly with it. The abacus spread to other countries like Japan and Korea. Teachers there still teach it in schools.
The abacus is not just a tool. It also has a special place in culture. In China, it is a symbol of wisdom and wealth. People even use words like “little abacus” to talk about someone who is always thinking about money. In Japan, there is even a special day for the abacus, called “Abacus Day”, on 8 August.
