[QUOTE=Pearl201se11 ...... when I was in school a cause of my disability was never found (but I do have hydrocephalus).
Maybe not much was known of dyscalculia back then, or maybe the educators were distracted by your condition (?disability you say?).
Which ever the case, you can be tested now ...and can be helped! At any rate, even in the abscence of diagnosis, whatever teaching strategies are employed to help those diagnosed with dyscalculia or any other learning difficulties (eg dyslexia), would also be helpful to you...you simply have to find a teacher qualifiedto do so.
I am assuming of course that you want to improve in mathematics?
