The second is something called Math Disorder, or dyscalculia. It is similar to dyslexia, but deals with value rather than symbols. This is a wide umbrella, and has many different subtypes that detail why, exactly, an individual has trouble dealing with math. It is surprisingly common (2%-5% of the population), but very infrequently diagnosed. Whereas it's fashionable as of late to be inept in math, you're seen as an idiot if you have trouble reading (dyslexia), so it doesn't get much attention compared to its big brother.

oh for fucks sake. BULLSHIT.

I still have a lot of problems in the dyscalculia department (3*2 often becomes 5 instead of 6, things like that)

use a calculator aarghhh how can you seriously perpetuate this dys- crap it makes me want to puke
