Three articles about mathematics and science braille are provided for braille transcribers and teachers of the visually handicapped. The first article discusses common problems such as setting braille writers incorrectly, duplicating transcribed materials unnecessarily, and incorrectly transcribing from typescript. The second article provides a June 1, 1983 Nemeth Code update concerning braille indicators, shapes, spacing, abbreviations, symbols of groups, and division. The third article presents a Nemeth braille quiz which highlights many unusual problems. Transcribers are asked to locate in the Code the section that correctly answers the questions. (LH)
