Dyscalculia is a widely used term for disabilities in mathematics. Whereas the term acalculia is reserved for the total inability to do math, dyscalculia refers to a less severe problem performing math problems. Dyscalculia can be developmental or acquired (e.g., traumatic brain injury), and the problem can range from mild to severe. Specific math computation and comprehension difficulties include problems with counting, recognizing numbers, manipulating math symbols (mentally or in writing), sequential memory for numbers and math operations, and reversing numbers (e.g., while reading, writing, and recalling numbers).
Difficulty in working with mathematical symbols and functions, presumably because of some brain dysfunction; one of the kinds of learning disabilities. Total inability to work with numbers is called acalculia.
When an individual finds it unusually hard to carry out simple mathematical calculations. It may be seen when the brain’s parietal lobe is diseased or injured.
An inability to make calculations. It may be found in childhood as a learning disability or may result from a stroke.
A condition characterized by challenges in resolving mathematical problems.
