I'm wondering about dyscalculia. Could it also apply where the person is actually very good at advanced maths, the point at which it really becomes its own language, with concepts that, from the outside at least, can seem very abstract, but struggles to, say, divide a cake into 6ths, work out a basic ratio (perhaps for a recipe) or generally develop a rough and ready sense of proportions and percentages in everyday life? Or would that be something else?
