Nemeth Braille

A specialized Braille code designed for representing mathematical and scientific notation, developed by Abraham Nemeth and adopted by the Library of Congress. Unlike literary Braille, Nemeth Braille has unique symbols for numbers, operators, fractions, radicals, Greek letters, and other mathematical constructs, enabling blind readers to read and write complex mathematical expressions. It is the predominant math Braille system in North America, while other regions use different math Braille codes (e.g., UEB Math in the UK and Australia). Modern web tools like MathJax can generate Nemeth Braille output using Unicode Braille symbols, pushing the output to refreshable Braille displays for real-time reading of web-based mathematics.
