[Blindmath] problems reading PDF scientific documents

[Géssica Michelle dos Santos Pereira]

Dear all,

I am Gessica, from the south of Brazil, with visual impairment, having
difficulties in reading PDF scientific documents, when they show
formulae.. I use screen reader Jaws and I've heard that LaTeX or
MathML might be useful but would you know how to convert the PDF
documents into these formats? .....moreover...how to use them?  I
wonder if you could help me find the solution.

Best regards,

Gessica Michelle
