Dyscalculia Math disabilities
A neurological mathematical disorder in which a person has trouble with time, solving arithmetic problems, and understanding math concepts and symbols.
It refers to a wide range of life-long learning disabilities involving math. Difficulties vary from person to person and affect people differently in school and throughout life. School-age children with language processing disabilities may have difficulty solving basic math problems using addition, subtraction, multiplication and division. They struggle to remember and retain basic math facts and have trouble figuring out how to apply their knowledge and skills to solve math problems.
Difficulties may also arise because of weakness in visual-spatial skills, where a person may understand the needed math facts, but have difficulty putting them down on paper in an organized way. Visual-spatial difficulties can also make understanding what is written on a board or in a textbook challenging.
