Nemeth Codes

The Nemeth code provide the blind with the tools to solve complex mathematical equations and scientific notations. The Nemeth code was created by Abraham Nemeth, who was a mathematics professor at the University of Detroit. These mathematical codes are based on the braille language, and therefore can be read just like normal braille documents are read.

The Nemeth code uses linear format, spatial arrangements, and special symbols to convey the meanings of the mathematical problems. The process of doing this can be done using a Perkins brailler, or special translation software. It is very beneficial to begin teaching children mathematics early, and there is no exception to this rule concerning blind children.

Nemeth Code for Math

There are some exceptional braille math books that contain Nemeth codes and can be easily read in the same fashion that other braille books are read, by running a finger over the raised dots. Graphs are usually displayed in tactile form, with additional braille being used to give further description. Braille mathematical texts are produced using an embosser, which can print on both sides of a page.

Once the sheets are run through the embosser, they are then either bound into braille volumes with thermoform sheets containing graphics or graphics from an Tiget embosser. These volumes contain both braille and print labels. A single regular text book may yield several braille books which are also larger in size. For small children, it may be that there are several smaller math books which are easier for them to handle.
