[Blindmath] User perspective for Nemeth Braille Code

[Rebecca Maria Carvalho]

Hi,
I am a teacher for blind and low vision students.
I would like to gauge the user perspective of those using the Nemeth Braille code to read and write Math.
Do students find it cumbersome when typing certain print symbols that require the use of 3-4 braille cells for one symbol?How is this coped with?
Also, when writing Math vertically, is maintaining alignment and scrolling easily manageable on the Perkins Brailler. For example when scrolling to carry over digits. Are there any specific techniques used to manage this?
Do let me know. Thanks!
Regards,Rebecca
