There is no gold-standard, universally applied definition of mathematics disability, and the literature is additionally complicated by the use of inconsistent labels (e.g., mathematics difficulties/underachievement/disability/disorder, developmental dyscalculia, reduced mathematics ability/skill), some of which differ conceptually. For the literature reviewed in this paper, we make no differentiation between these labels and concepts. However, for the data shown in this paper, we consider the term ‘mathematics ability’ to refer to a normally distributed complex trait that ranges from low (disability) to high (ability).
