Place-value structure of the Arabic number notation is a key to why math is difficult for a subgroup of people with dyscalculia
Developmental dyscalculia (DD) is a math-specific learning difficulty that is believed to be a multi-cause condition. Former measurements found that typically developing adults and children process place-value number notations (such as the Arabic numbers) harder than sign-value notations (such as the Roman numbers) in simple mathematical tasks. Computational considerations suggest that place-value notation processing requires […]
