What does dyscalculia affect?

Dyscalculia specifically affects a person's ability to process mathematical concepts, which includes understanding numbers, performing calculations, and understanding the order of numbers. Individuals with dyscalculia may struggle with basic arithmetic, number sense, and problems involving quantities and time. The condition can impact how they perceive numerical information and may pose challenges in everyday situations that involve math.

The other options pertain to different learning disabilities: reading comprehension is affected by dyslexia, written expression is linked to dysgraphia, and visual acuity relates to eyesight and does not reflect a cognitive processing issue like dyscalculia does. This specificity is essential in understanding the unique nature of learning challenges and tailoring educational approaches accordingly.
