About Master Tai Chiang Ching

As a child, Master Tai Chiang Ching showed a flair for numbers and a keen interest in the abacus and mental arithmetic. Upon his retirement from the army, he devoted all his time to study abacus calculation before setting up the first CMA Institute in Taiwan in 1984. In the same year, he became the committee member of the Association of Children’s Abacus Calculation in Taiwan. In 1991, Master Tai was named the World’s Best Mental Arithmetic Trainer, an award given to teachers who have made long term and significant contributions to educating and moulding young minds. Under his tutelage, two of his students, Lin Zi Yin and Su Wan Ting, achieved phenomenon success, having been crowned world champion in Mental Arithmetic Competition and having achieved the highest attainment of grades in the Abacus and Mental Arithmetic Examination respectively.

Having spent over 20 years researching and experimenting with various techniques to improve abacus calculations, Master Tai had perfected the traditional method of the single-hand abacus arithmetic calculation. In 1992, he went on to develop a new two-hand (i.e. using four fingers on the abacus) mental arithmetic system which is widely used at CMA Institutes worldwide today. This new system of calculation enabled users to use their left brain to manipulate the virtual image of the abacus in their head while using the right brain to achieve fast mental calculations at the same time

As the president of Yu-Ming Publishing Co. Ltd, Taiwan’s largest publisher of abacus mental arithmetic books, Master Tai has also penned and published over 200 arithmetic books, including CDs and VCDs on abacus mental arithmetic.
