Which of the following learning disabilities is primarily associated with difficulty in performing mathematical calculations, understanding numbers, and recognizing mathematical symbols or signs?

→ What is meant by 'Learning Disability' in education? → 'Dyscalculia', a type of learning disability, is related to which of the following? → What is the primary characteristic of the learning disability 'Dyslexia'? → The learning disability 'Dyspraxia' is primarily related to which of the following? → In the context of learning disabilities, which of the following represents the most subtle and factual distinction between 'Dysgraphia' and 'Dyspraxia'? → An eleven-year-old student experiences extreme difficulty during reading and spelling in class, such as reversing letters (e.g., reading 'was' as 'saw'), failing to understand spaces between words, and struggling greatly to read long sentences. However, his oral expression, logical ability, and intelligence quotient (IQ) are normal for his age, and he has no visual or auditory impairment. This condition primarily points to which specific learning disability, and what is considered its most accurate neurological cause? → A 10-year-old child reverses words while reading, confuses the sequence of letters (such as reading 'was' as 'saw'), and experiences severe difficulty in understanding visual cues. Psychological tests reveal that his intelligence quotient (IQ) is normal, and his auditory capacity is also completely fine. Which specific learning disability is this child most likely to have, and how does it affect him at the neurological level? → In the context of scientific classification and clinical symptoms of specific learning disabilities, if a learner experiences severe difficulty in understanding mathematical symbols, recognizing place value of numbers, performing calculations, and logically solving verbal mathematical problems, while their general intelligence quotient (IQ) and reading-writing abilities are completely normal, what is this specific learning disorder called and what is its primary psychological/neurological basis?
