[Blindmath] Mathematics using handwriting

Just so everyone is clear, I at no point was talking about describing graphs.  I thought we only talking about mathematical text such as equations or formulas.  Also, I would say that pretty much everything that is represented graphically and visually can be represented without the visual through he actual math such as a table.  Also, I know that isn’t always sufficient, but you should always have a variety of tools in your toolbox.

Mathematical notation is really just fancy text. It has a well-defined reading order and is regularly spoken by sighted people, though usually only in parallel with the visual representation. It is true that it is harder to understand math from only spoken text, such text is very much the actual equation, not a description of it.
