Inability to do math, dyscalculia, is poorly understood. When a child has dyscalculia, only math is difficult, and the lag is highly at odds with the child's overall level of intelligence and performance in other subjects. The child has difficulty with orientation in time and space, as well as problems with logical and grammatical constructions. I've studied a lot about this, but I don't agree with half of it either. I don't believe that if you don't know math, you have a problem. There are so many helper sites like
this now that you don't need to learn math.
