What is Nemeth Code?

Nemeth Code is the standard code of braille notation used for math and science.  It was developed by Dr. Abraham Nemeth in 1946, and was adopted by BANA (Braille Authority of North America) in 1952 as the standard code to represent mathematic and scientific notation, using the 6-dot braille cell.

 

How Can I Learn Nemeth Code?

The Nemeth Tutorial is a project with American Printing House for the Blind (APH) that is designed to teach students and teachers how to use the Nemeth code for all levels of mathematics, from introductory to advanced topics. 

There are 11 chapters are organized by grade level, from 1st to 8th grade, and then by content area for algebra, geometry and advanced mathematics.
