Dyscalculia is a condition that affects the ability to acquire mathematical skills. It is unrelated to age, level of education or experience and occurs across all ages and abilities. Dyscalculic learners may have a difficulty understanding simple number concepts, lack an intuitive grasp of numbers, and have trouble learning number facts and procedures. Even if they produce a correct answer or use a correct method, they may do so mechanically and without confidence.
It is estimated about 6% of the population have dyscalculia but studies into dyscalculia are about 30 years behind studies into dyslexia.
