Dyscalculia is a math learning disability that impairs an individual's ability to represent and process numerical magnitude in a typical way. Some people call it "math dyslexia." Common symptoms of dyscalculia include difficulty with number sense, fact and calculation, and mathematical reasoning Lesion studies in patients with acquired dyscalculia have primarily implicated the left parietal coex, paicularly near the angular gyrus Functional studies of calculation show a more complex activation pattern. Additionally, dyscalculia often occurs in the context of Gerstmann syndrome Ref Harrison20th edition pg 2456
