How do you teach a blind and deaf person?

Hello!

To not get you confused or give you too much information:

In Short,

Deaf-blind people use many different ways to communicate. They use sign language (adapted to fit their visual field), tactile sign language, tracking, tactile fingerspelling, print on palm, tadoma, Braille, speech, and speech reading etc. 

And Many Other More of Course!

Hope this Helps You! Have A WONDERFUL DAY! :)

(Ps. Dont Forget To Mark As BRAINLIEST!)

And as Always...
