If a child is good in arithmetic but not in languages or if the child is good in languages and is poor in computing the numbers, it could be a case of 'Specific Learning Disability' although to be honest I hate these type of 'labels'.

I agree with Latha Vidyaranya, a counselor for children with learning, emotional and behavioural problems

"These labels (should be used) only to exchange information between professionals and to understand the remedial measures required for the child, but not to demoralize the child or the parent."

"Once we have identified a child with these difficulties, what do we do?
The child needs an assessment by an Educational psychologist or a Special Educator who may administer various tests to find out the its abilities in the areas of reading, writing, spelling and arithmetic.
It is important to rule out any hearing or vision problems before conducting these tests.
It is also important to collect information about the family history/background to rule out any serious emotional disturbances."
