I have learned many digits of Pi, more than a thousand, but that is it.
I cannot work with numbers, as I am visually thinking and to do math one needs working memory and I do not have a good one, I see the numbers but I do not see the concepts to work with them.
I do look at number plates, and I recognize for example when family is coming for a visit them by the number plate of their car due to face blindness, so I have remembered all their number plates.
