Specific learning disability involving math calculation.
A serious difficulty with understanding and doing math.
impaired ability to learn grade-appropriate mathematics
a mathematics disability in which an individual may have difficulty both learning mathematical concepts and applying them consistently and confidently
a form of Specific Learning Disability that involves a delay or inability in learning arithmetic facts and operations, and their meaning.
A severe difficulty in understanding and using symbols or functions needed for success in mathematics.
inefficient understanding of or use of arithmetic symbols or functions (see acalculia).
Difficulty in understanding or using mathematical symbols or functions. A child with dyscalculia may be able to read and write but have difficulty in performing mathematical calculations.
A learning disability in which a child is unable to do math problems.
A learning disability that makes it difficult for a person to understand and use math concepts and symbols.
Impairment to the ability to perform mathematical functions. A child with dyscalculia may be able to read and write but have difficulty in performing mathematical calculations.
Inability to carry out mathematical calculations.
People with this disorder have severe difficulty in understanding and using functions or symbols needed for success in mathematics.
Dyscalculia was originally identified in case studies of patients who suffered specific arithmetic disabilities as a result of damage to specific regions of the brain. Recent research suggests that dyscalculia can also occur developmentally, as a genetically-linked learning disability which affects a person's ability to understand, remember, and/or manipulate numbers and/or number facts (e.g. the multiplication tables). The term is often used to refer specifically to the inability to perform arithmetic operations, but is defined by some educational professionals and cognitive psychologists as a more fundamental inability to conceptualize numbers as abstract concepts of comparative quantities (a deficit in "number sense"Dehaene, S. 1997 The Number Sense: How the Mind Creates Mathematics New York, Oxford University Press.).
