What does dyscalculia affect?

Dyscalculia is a specific learning disability that primarily impacts an individual's ability to understand and work with numbers. This condition affects mathematical operations such as addition, subtraction, multiplication, and division, as well as number recognition — meaning individuals with dyscalculia may struggle with understanding numerical symbols, basic arithmetic concepts, and mathematical reasoning.

This means that someone with dyscalculia might find it challenging to perform calculations, recognize patterns or relationships among numbers, and develop the mathematical skills necessary for academic success. The impact of dyscalculia is unique and distinct from challenges in reading comprehension, written language composition, or general memory retention, as those areas relate to different cognitive and learning processes. Therefore, the correct answer highlights the specific nature of dyscalculia in relation to mathematical abilities.
