DYSCALCULIA
Dyscalculia or math disability is a specific learning disability or difficulty involving innate difficulty in learning or
comprehending mathematics. It is akin to dyslexia and can include confusion about math symbols. Dyscalculia
can also occur as the result of some types of brain injury.
Dyscalculia can also occur developmentally, as a geneticallylinked learning disability which affects a person's
ability to understand, remember, or manipulate numbers or number facts.
Symptoms:
• Frequent difficulties with arithmetic, confusing the signs: +, −, ÷ and ×.
• Difficulty with everyday tasks like checking change and reading analog clocks.
• Inability to comprehend financial planning or budgeting, sometimes even at a basic level; for example,
estimating the cost of the items in a shopping basket or balancing a checkbook.
• Difficulty with multiplicationtables, and subtractiontables, addition tables, division tables, mental arithmetic, etc.
• May do fairly well in subjects such as science and geometry, which require logic rather than formulae, until a
higher level requiring calculations is obtained.
• Difficulty with conceptualizing time and judging the passing of time. May be chronically late or early.
• Particularly problems with differentiating between left and right.
• Might do exceptionally well in a writing related field many authors and journalists have this disorder
• Difficulty navigating or mentally "turning" the map to face the current direction rather than the common North=Top usage.
• Having particular difficulty mentally estimating the measurement of an object or distance (e.g., whether something is
10 or 20 feet (3 or 6 metres) away).
• Often unable to grasp and remember mathematical concepts, rules, formulae, and sequences.
• An inability to read a sequence of numbers, or transposing them when repeated, such as turning 56 into 65.
• Difficulty keeping score during games.
• Difficulty with games such as poker with more flexible rules for scoring.
• Inability to concentrate on mentally intensive tasks.
• Low latent inhibition, i.e., oversensitivity to noise, smell, light and the inability to tune out, filtering unwanted
information or impressions. Might have a welldeveloped sense of imagination due to this (possibly as cognitive
compensation to mathematicalnumeric deficits).
• Mistaken recollection of names. Poor name/face retrieval. May substitute names beginning with same letter.
