I am numerically challenged. I have to look back at a printed phone number for every single number before entering on phone keypad. Always incorrectly transcribing numbers. Math classes - a nightmare I still have.

Navigationally challenged too with trouble determining left from right.

I think all of these problems are linked.

On the other hand, I like sudoku. But it's not numbers to me, it's patterns, which I am good with. Also good at mechanical reasoning according to the Indiana tests.

Where my partner lectures, the college has dyscalculia on the list with dyslexia for receiving assessment and support. Guess things are a bit different in the UK regards this disability.
