[BlindMath] synthetic division

[John Miller]

Hello, I do polynomial division to this day using a Perkins braille writer. It is a key concept and data communications in engineering. Also finding the inverse of a three-dimensional or a four dimensional matrix is quite useful on a Perkins braille writer, despite having access to a single line braille display very best John.
