I can understand trying to teach someone via visuals or by talking to them but I can’t figure out how you would teach someone multiplication or about government services or scammers without either.

Helen Keller naturally came to my mind as well. She was not born blind and deaf though. She lost those sense at 19 months, so about a year and a half in. That is still quite young, but enough to establish the basis for things like object permanence and 3 dimensional space. In the climatic scene of The Miracle Worker, the main character says a word she learned as a baby, underscoring the importance of her early months.
To truly be born deaf and blind I think would be another degree more challenging.
