Question: is this something you're born with or can it develop over time? I never had problems with numbers until a few years ago. Now I reverse the numbers sometimes. I see, for example, 43 as 34. I make this mistake quite often and I used to be dead-on if someone told me a telephone number. Now I have to write it down, and still I have to check to make sure I've not reversed a pair of numbers in there somewhere.
