This study is, that is, represented the braille code of mathematics and the method of management in three countries, Korea, Japan and USA(Nemeth Code), and done comparative-analysis of the system with each country. The mathematics notation in ink print is greatly categorized to a linguistic-algebraic and a visual symbol. The symbol is a generally meaningful of a linguistic-algebraic symbol.
It is represented the system of the common principle, that the braille code of mathematics is also symbolized as the same method in all countries by the oriented a linguistic-algebraic symbol, added to symbolize and establish the visual symbol of graphic matter. In addition, the braille code of mathematics is determined by the sequence of shape-oriented, mean-oriented, and supplements that is used to specific rules, and we can know, in according to the rules that of each country is determined. The number of the braille code of mathematics is represented in each country. There were 356 in Nemeth Code, 250 in Korean and 231 in Japan in the number of mathematics braille. As the result that compares with the braille code of mathematics of three countries, they are approximately accordance to the braille, such as alphabets, fourth operations, sets, and a punctuation mark (an arrow, a parenthesis and so on). 2/3 of the braille code of mathematics between Korea and Japan was accordance. However, there were not the same things in the Nemeth Code. It is represented that established through the way that make remind the shape of ink print easily on determining the components of numerical formulas and symbols in all of the mathematics of three countries.
Key words : Braille, the Braille code of mathematics, Nemeth code
