[BlindMath] info request for software supporting partially sighted students

[Sauro Cesaretti]

Hi all,
Im Sauro Cesaretti from Italy.
I'm blind from Birth, studied computer science and explored several 
solutions to write and work with mathematics.
At the moment I'm looking for a good soolution for partially sighted 
students that I'm supporting for their studies.
Specifically, I'd need a software to write and work math notation and a 
solution to work with geometry in gelera: cartesian plane, calculating 
and elaborating figures and so on.
Thank you very much in advance for all your advices.
Best regards, Sauro Cesaretti
