[Blindmath] how to get LaTeX formats of mathamatical content

[Rekha]

Hi
In recent days i came to know about LuTeX formats of mathamatical contents.
what is it?
whether we can convert pdf's by ourselves into this ?
or else we need some other accessable formats?
could anybody please give me more details about this.
i am faceing many problems in reading pdf's of statistics.
any inputs in the above regards are most welcome.
thanks& regards
