Understanding Dyscalculia - When Numbers Do Not Make Sense
Dyscalculia
Dyscalculia is not a math weakness. It is a neurological variant where the brain processes numerical cognition differently. The intraparietal sulcus - the brain region responsible for quantity representation - shows different activation patterns in dyscalculia.

User question
Why can I not imagine how much 47 is? I know it is a number, but I do not see a quantity.

That is a difference in quantity representation. Your intraparietal sulcus (IPS) maps numbers less automatically to spatial quantity experiences. Neurotypical brains intuitively generate a spatial representation for "47" - roughly here on a mental number line. Dyscalculic brains have this automatic mapping process weakened or absent.
You understand the number abstractly. The intuitive quantity representation is missing. This is not a comprehension deficit - it is a representation difference.

Working memory and numbers
Calculation requires holding multiple numbers and intermediate results in working memory simultaneously. In dyscalculia, the capacity of numerical working memory is often reduced - not general working memory, but specifically for numerical information.
User question
I forget the first number before I have added the second. Why?
Divergent Mirror (Self)
That is numerical working memory. Mental arithmetic requires storing intermediate results while simultaneously executing the next operation. Your brain allocates less working memory capacity for numerical information. This does not affect texts or faces - only numbers.
It is not an attention problem. It is a domain-specific capacity limit.
Your brain calculates - on a different path
Dyscalculia is not a question of intelligence or practice. The intraparietal sulcus explains why quantity representations are not intuitive. Numerical working memory explains why mental arithmetic is disproportionately exhausting. And the domain-specific nature of the mechanism explains why dyscalculia is not noticeable in other areas.
