For example, dot 4 followed by letter “a”
indicates @ - at the rate of. Please see that @ resembles (a). This logic may be applicable
to many scripts. For example, the dollar sign ($) looks like (s) and therefore, the script
indicator followed by letter (s) indicates dollar. Similarly, script indicator followed by
letter (l) indicate pound sterling, and so on. At the secondary level, the following scripts
are commonly found and therefore, the learner needs to know these.
- cent - ∋ reverse membership
- ∈ (an element of) - % percent sign
- (Pound Sterling) - ∗ Asterik
- $ Dollar - 4 Check mark
For other higher order signs using the script indicator you can refer to the Nemeth Braille
code book.
Base Code 9: Dots 1,2,3,5, and 6
Opening Parenthesis ( )
Parentheses are used in every expression, whether in literary description or in mathematical
equation. For example, the expression (apple) uses ‘(’ as the opening parenthesis and ‘)’
as the closing parenthesis. In numbers too – (x+2), parentheses are used. For open
parenthesis, dots 1,2,3,5, and 6 are used. Similarly, ‘[’ (square open bracket) and ‘{’
(curly open bracket) are also used as open parentheses. For changing the simple open
parenthesis into a square open paranthesis, there is a need to insert dot 4 before the
parenthesis sign. Similarly for curly open parenthesis, dots 4 and 6 are inserted before the
parenthesis. Therefore, the three types of open parentheses are written as follows:
