You learn something new when you have an AVM. As a result of a random event, reading a math problem on a fishing forum, I had something diagnosed. Dyscalculia, is a difficulty with mathematics.
I have had this issue with higher mathematics, starting with algebra with me. It has deteriorated to 3 digit long division. Honestly, I had difficulty telling time until I was in 7 or 8 grade.
I have about 1/2 the symptoms listed on the wikipedia and I’m going to do research into more reliable sources.
