A propos de cet article

Stapled wraps; square, 9.25 by 9.254 inches; 67 pages with instructional illustration with the 33.3 LP. Carefully used and handled, come upper corner wear; pages evenly age-toned. Chisanbop sometimes called Fingermath, is a finger counting method used to perform basic mathematical operations. According to The Complete Book of Chisanbop by Hang Young Pai, chisanbop was created in the 1940s in Korea by Sung Jin Pai and revised by his son Hang Young Pai, who brought the system to the United States in 1977. With the chisanbop method it is possible to represent all numbers from 0 to 99 with the hands, rather than the usual 0 to 10, and to perform the addition, subtraction, multiplication and division of numbers. The system has been described as being easier to use than a physical abacus for students with visual impairments.
