Dyscalculia is known by several terms:
(1) Specific Learning Disability / Disorder in Mathematics (SLD-Math)
(2) Math Learning Disability (MLD)
(3) Developmental Dyscalculia (DD)
(6) Math Dyslexia
(7) Math Anxiety
(8) Numerical Impairment
(9) Number Agnosia
(10) Non-verbal Learning Disorder / Disability (NLD)
