Above is a link to a site that describes something called Dyscalculia. It is basically like dyslexia, except for words and letters, its math and numbers. I think I may have this. I have always struggled with math, and I still do, though with lots of practice it is better. Good enough to get through the day. I think most of that was strenuous practice when I was a cashier. There was one place I worked at where I was required to count change back to the dollar before they let me on the register. Not only that, but I was trained with a group. This was extra incentive to get it right. So, I bought a bag of play money, went home and practiced it. Even if my register broke I could, without error, count back your change to the dollar even to this day.
As a child, I really struggled through math tasks. When I had to work, I had to rely on counting on my fingers, which was very frowned upon by my second grade teacher.It got to the point to where she recommended I be tested for special ed. Even though this was 20 yrs ago, they did special ed testing quite a lot the same as today. I was tested in all areas and when was all said and done I was found to be gifted, with the exception of math, of course. The school forgot all about my math issues and focused on the where I can get my needs met in all the other areas. Which was okay, because I was just as bored in class as they thought I to be after seeing where I was academically. The school I attended was very small and didn't have a gifted program for grade school students, so the faculty tried to move me up a grade in effort to alleviate my boredom. I as a young aspie child was vehemently opposed to such a drastic change. So, I remained in the same grade, but without any aid in my math skills, which seemed more and more behind with each passing year. By the time I got to algebra I was failing. I had no concept of what to do and no amount of extra tutoring seemed to help. I wish that I had gotten the extra help when I was young. I get by, but still count on my fingers. ;)
