Nemeth Code Basics

Nemeth Code Basics
We will go over three worksheets in this workshop, including how they are
formatted.

Notice in the numbers below that literary numbers are in the upper part of
the cell. Nemeth numbers are in the lower part of the cell.


The first portion of this worksheet shows numbers. Because Nemeth
numbers are in the lower part of the braille cell, the punctuation indicator is
needed after problem numbers and before punctuation. The punctuation
indicator is |=(dots 456).

Directions are in cell 5 with runovers in cell 3. A blank line is left before
directions unless they follow a page-change indicator. When a cell-5
heading is before directions, a blank line is required between the cell 5
heading and directions.

No blank line is left after directions unless they are followed by spatial
material.

Special typeface is ignored in directions.

In the example below, a centered heading precedes the directions. There
is a blank line after the heading.

The number to the right of the problem has been moved to the beginning
of the directions. This is a section number to reference within the chapter.

Superscripts and Subscripts

The normal level of writing is called the baseline.

When a number or letter is elevated it is called a superscript.

When a number or letter is lowered it is called a subscript.

The baseline indicator is used to put the level of writing back to the normal
level. The indicator is not used when there is a space or punctuation
indicator following the superscript or subscript.


Subscript indicators are not used when a letter from any alphabet has a
subscript of a number. The number can have a decimal point or a
comma, but cannot have a superscript or subscript of its own.

When a subscript indicator isn’t used, the baseline indicator isn’t needed,
like in the example below.


This section shows directions followed by itemized problems. The
directions are in cell 5 with runovers in cell 3.

Problems begin in cell 1, with runovers in cell 3. The problems below are
itemized, but do not contain subdivisions.

The letters in the problems below are variables. No letter indicator is used
unless the variable stands alone and is not part of an equation.

Fractions

Simple Fractions: When writing simple fractions, be sure to use the
opening and closing fraction indicators.

Be sure that the number sign isn’t used instead of the opening fraction
indicator.

The opening fraction indicator precedes the numerator (top of fraction),
the closing fraction indicator follows the denominator (bottom of fraction).

Mixed Number Indicators

A mixed number is an expression which begins with a numeral and is
followed by a simple fraction whose numerator and denominator are both
numerals.

An expression is not a mixed number if it contains any letter, even if the
expression is in the same form as a mixed number.

Nemeth Comma

The Nemeth comma is made up of dot (6)


Symbol of Omission

The symbol of omission is made up of dots (123456).

This symbol is used for spaces that are blank, or contain a question mark.
It is not used for blank lines in print.

It is spaced the same as what it replaces.


The symbol of omission is used for the question marks above blank lines
below.

Notice that the word with is uncontracted in directions for problems 19-21.
A word in direct contact with a sign of comparison can't be contracted.

The baseline indicator is used before the fraction line and closing fraction
in problems 17 and 18 below.

Notice the mixed fractions in problems 24 and 25.

Line Over

When there is a single line over a number or letter, lower-case or
uncapitalized, from any alphabet, the symbol below is used. If the line is
over more than one letter, refer to the five-step rule in the Nemeth Code,
Section 86.

A space is required before and after signs of comparison. The numeric
indicator is repeated after the comparison sign.

Spatial Problems

In spatial problems, the numeric indicator isn’t used.

There are blank lines above and below spatial problems, even when there
is a page change indicator above or below them.

The separation line is made up of dots 25.

There must be one blank cell between separation lines when more than
one problem is written across the page.

The separation line goes one cell to the right and left of the widest item in
the problem.

When spatial arrangements are identified by a number or letter, no symbol
of one spatial arrangement may be less than 3 cells distant from any
symbol on any line except separation lines.
Mary Denault CTEBVI 2010
Page 17
Addition and Subtraction

Plus and minus signs are placed in the cell to the left of the widest number
which appears above the separation line. If they are deliberately
misaligned, follow print.

Multiplication

The multiplication cross is written in the cell next to the first digit above the
line.

The Review and Name at the top of the page are left aligned.

The heading for the worksheet is centered.

Directions are in cell 5. A blank line is required below the directions
because of the spatial material that follows.

Blank Line

The blank line is used to show a space to be filled in when a blank line is
shown in print.

The blank line is spaced like what it is replacing.
JJJJ==Blank Line (dots 36, 36, 36,36)
Examples:
@S]GT=Kh=JJJJ=
Mary Denault CTEBVI 2010


Blank lines are shown below. Notice that they are spaced away from the
sign of comparison (equals).

Two different symbols are used for division. Follow print for the symbol to
be used. (See page 10 for symbols)

Itemized material with subdivisions is shown below. The main
division goes in 1/5, subdivisions are in 3/5. This is a Nemeth rule.

The dollar sign ]p=is used below. The numeric indicator isn't
used with the dollar sign.
