Những điều cần biết lúc bắt đầu

Độ tuổi học bàn tính theo như nghiên cữu của hội đồng bàn tinh (ở Nhật):

“According to the Abacus Committee, average students, who begin their practice while in their teens, should be able to pass the examination for third-grade licenses after half a year of daily practice of one hour, and bright students or students with a mathematical bent after only three months.

Generally speaking, another half year of practice will enable a third-grade abacus operator to obtain a second-grade license; and one more full year should make him a first-grade operator. As is generally the case with any other art or accomplishment, it is best to start practicing under right guidance when young. Those who take up their study of the abacus after they are out of their teens are never able to pass the first-grade examination, but it is definitely possible for them to attain to the third rank, and occasionally even to the second”
