Impairment in the ability to solve arithmetic problems.

• A. Dyslexia
• B. Dysgraphia
• C. Dyscalculia
• D. Aphasia

Answer: (C)

This item focuses on a math-specific learning disability. When a learner has difficulty understanding numbers, recognizing quantities, or performing arithmetic operations and retrieving math facts, this pattern is dyscalculia. It specifically affects solving arithmetic problems and math-related reasoning, distinguishing it from other learning issues.

Dyslexia involves struggles with reading and decoding written language, dysgraphia concerns handwriting and written expression, and aphasia is a language impairment usually resulting from brain injury. While dysgraphia can make writing out math problems harder, the core challenge described here—trouble solving arithmetic problems—best fits dyscalculia.
