Dear friends, screen reader users, teachers and assistants.
I am trying to find out what tools can I use to create math content. I know #mathml is supported accross variety of screen readers and browsers but that seems to be only one side of the puzzle and that is reading.
How do I as a student collaborate on math content with my teacher and the other way round, how do I as a teacher create accessible math assigments for my student allowing them to complete it with a screen reader?

For this answer let's explore that both student and teacher are blind or visually disabled or teacher is sighted, student is blind. How to collaborate?
