Resumo
Number processing and calculation system are composed by different elements that work independently. Objective: The objective is to determine relationship between number reasoning and calculation. The numerical reasoning and the calculation is evaluated in two patients with cerebral acquired damage. Patients and method: On one hand, a patient with frontal injury of left hemisphere that presents executive disfunction and on the other hand, a patient with injury of perisilvian area of the left hemisphere that presents alterations in the production of the oral language. Results: the patient with linguistic alterations is capable of solving problems and of reasoning with numbers, nevertheless he cannot execute simple arithmetical operations isolated (not in oral form not written). On the other hand, patient of frontal damage executes calculation isolated or abstract, both in oral and written form, even realizing procedures of taking, but she cannot solve problems of reasoning numerical simple. Discussion: number reasoning, that is, the resolution of problems by the use of numerical symbols, and isolated calculation work independently. These results can be explained from the actual processing number and calculation models.
