Therefore, the Braille configuration for the expression is
Similar to the insertion of shape inside the circle, assume that we want to insert a symbol
(+). Here, the (+) is not a shape, but inserting the (+) inside the circle is modifying the
meaning. Therefore, the inner shape modifier should be used but before (+), there is no
need to use shape indicator since (+) is not a shape. The Braille configuration is as
follows:
Through the above operations, we understand that the shape can be shown independently,
shape shown within another shape, and a sign shown within a shape. Using these
operations in exercises will help you remember the procedures as well as codes. One rule
of thumb is that you remember the procedures before writing the codes.
Let us illustrate the use of structural modifier with shape indicator. Let us take the shape
triangle. It is indicated by
Though this is the basic sign for the triangle, there needs to be a difference between
isosceles triangle, right angle triangle, scalene triangle etc. Here note that you have to
change the structure of the shape. Therefore, the structural modifier (dots 4 and 6) should
be used. The easiest way to understand this process is that the right angle triangle should
be called triangle right angle, isosceles triangle as triangle isosceles and so on so that the
child understands that the code for triangle should be written first and then the modifier
used to indicate the change of shape. The first letter of the modified shape should
normally follow the structural modifier and finally, the operation should be closed by
inserting the termination indicator. Therefore, the right angle triangle is written as
