When it comes to abacus mental arithmetic, refers to a technique of performing quick calculations through mental arithmetic. Abacus mental arithmetic usually uses a string of beads arranged on a stick, with each bead representing a specific number.
This technique originated in ancient China and can be traced back to about two thousand years ago. The basic principle of abacus mental arithmetic is to use beads in different positions to represent different digits, so as to perform mathematical operations such as addition, subtraction, multiplication, and division.
These beads are arranged in a specific structure, such as "a row of ten beads" or "a row of five beads", etc. By moving, swinging, color distribution, etc., calculators can quickly perform various arithmetic operations.
Training in this technique requires extensive practice to develop the calculator's intuition for bead placement and manipulation. After a long period of practice, abacus mental arithmetic can allow calculators to perform complex mathematical calculations quickly and accurately without any tools.
Although with the development of modern computer technology, it is very common for people to use calculators and computers for calculations, abacus, and mental arithmetic, as ancient skills, are still preserved and passed down in some places, and also exist as a cultural heritage and educational method.
There are some famous abacus and mental arithmetic competitions in the world, which usually attract participants from different countries and regions to demonstrate their competitiveness in abacus and mental arithmetic skills. Here are some famous abacus mental arithmetic competitions:
1. Abacus Mental Arithmetic World Cup: This is an international abacus and mental arithmetic competition held every two years. Abacus and mental arithmetic players from all over the world will compete in different age groups, including addition, subtraction, multiplication, division, and other calculation items.
2. National Abacus and Mental Arithmetic Conference in Japan: Japan is one of the birthplaces of abacus and mental arithmetic, so the National Abacus and Mental Arithmetic Conference held in Japan is also of great significance. This competition brings together abacus and mental arithmetic players from all over the country to demonstrate their calculation ability at different ages and levels.
3. Asian International Abacus Mental Arithmetic Championship: This is a competition that gathers abacus and mental arithmetic players from various countries in Asia, covering a variety of different calculation items and age groups.
4. International Abacus and Mental Arithmetic Olympiad: This is an international abacus and mental arithmetic competition for children and teenagers, aiming to encourage the younger generation to learn and develop abacus and mental arithmetic skills.
These competitions not only demonstrated the players' amazing abacus and mental arithmetic skills but also promoted the inheritance and development of this ancient skill. They also provide a platform for people from all over the world to come together to exchange experiences, share tips, and compete to demonstrate their abilities in mathematical calculations.
