Matrices

- The numbers, letters, and other symbols in a matrix must be properly aligned in order to be understood.
- Precise formatting is essential.
- Table formatting might be useful, as well as left-align or right-align functionality.
- Columns should be left adjusted except for minus signs, which should be brailled to stand out ((GTM 5.2)
- When enlarged grouping indicators are used, these should be vertically aligned.
- A matrix in braille may also be preceded and followed by a blank line or a top and bottom box line.
- One column of blank cells should be left between each column of data.
- Signs of operation and comparison should be placed on the top line even when they're centered in print.
- I'm attaching a sample in Unicode braille.
