Different intervention strategies for multiplication.

She was observed to have mixed up the arithmetical procedures and inadequately oriented the columns in mathematical problems. Studies of patients with lesions to the parietal lobe have demonstrated that lesions to the angular gyrus tend to lead to greater impairments in memorized mathematical facts, such as multiplication tableswith relatively unimpaired subtraction abilities.

Please help to improve this article by introducing more precise citations. Shortly after Henshen’s advances, Berger in distinguished between primary and secondary acalculia.

Double dissociation between rote verbal and quantitative knowledge of arithmetic.
