Dyscalculia is a learning disability where the student has serious problems in mathematics, more specifically, related to mathematical calculations and reasoning. This disability prevents the student from obtaining the skills that student need to perform mathematical calculations (Raja & Kumar, 2011, p. 41). This disability can take on many forms, including the inability to take the knowledge he or she knows, and relate it to quantities, difficulty in reading or writing numbers and mathematical symbols, difficulty understanding mathematical ideas, the inability to perform basic arithmetic, and problems with calculating time and taking measurements (Raja & Kumar, 2011, p. 42). This is not the only definition and many researchers have their

Ladislav Kosc. In 1974, Dr. Ladislav Kosc wrote his paper on dyscalculia called Developmental Dyscalculia in the Journal of Learning Disabilities (Kosc 1974). In this study, Dr. Ladislav Kosc identified six types of developmental dyscalculia; difficulty talking about mathematical concepts, difficulty coming up with a number, difficulty reading mathematical symbols, difficulty writing mathematical symbols, difficulty understanding mathematical ideas, and difficulty performing specific mathematical operations. Dr. Ladislav Kosc also stated that someone with dyscalculia may not have difficulties in all areas, that person may just have a problem in one of the subtypes or a combination of the subtypes (Chia & Ng, 2010, p. …show more content…
There is also a belief that those with dyscalculia have genetic deficiencies in the X-Chromosome and that brain scans have shown that those with this disability have fewer brain cells on the left side of their brain (Chia & Ng, 2010, p. 15). Time will tell if we have more theories on dyscalculia, since this is still a relatively new and researched learning disability.
There are also some theories that suggest a dyscalculia is independent to other learning disabilities. Studies have shown that dyscalculia is independent from dyslexia and ADHD. There are some theories that other learning dishabilles may be linked with dyscalculia, but there needs to be more research on the subject before it is known if there are any links with dyscalculia and other disabilities (Raja & Kumar, 2011, p.
