A specific learning disorder with impairment in mathematics (often referred to as dyscalculia) is associated with significant difficulty understanding numbers and working with mathematical concepts.

Dyscalculia is a term referring to a wide range of difficulties with maths, including weaknesses in understanding the meaning of numbers, and difficulty applying mathematical principles to solve problems. Dyscalculia is rarely identified early.

Not knowing which of two digits is larger, i.e. understanding the magnitude and relationship of numbers

Lacking effective counting strategies

Poor fluency in identification of numbers

Inability to add simple single-digit numbers mentally

Limitations in working memory capacity

More information

Studies have been done to try to identify predictors of potential mathematical disability. The main predictors include:If basic maths facts are not mastered, many teenagers and adults with dyscalculia may have difficulty moving on to more advanced maths applications. Additional language processing disorders can make it difficult for a person to grasp the vocabulary of maths. Without a clear understanding of this vocabulary, it is difficult to build on maths knowledge.Success in completing more advanced maths problems requires the ability to follow multi-step procedures. For individuals with learning disorders, it may be difficult to visualise patterns, different parts of a maths problem, or identify critical information needed to solve equations and more complex problems.
