Abstract Background: From a neuropsychological point of view calculation is a very complex function. A simple arithmetic operation demands many neurocognitive mechanisms that involve verbal, spatial and graphical processing, memory and attention. Objective: To verify the calculation and number processing of healthy subjects and the effect of gender, age and schooling on their performance. Method: Forty-four normal subjects without complaints or neurological changes were evaluated. Results: The educational level was significantly linked to performance in the majority of tests of the EC 301 battery, whereas no differences were noted regarding age and gender. Conclusion: Evaluation of the data of the healthy population shown in this study indicated that educational level can affect calculation and number processing, It is possible to note that battery EC 301 demonstrated sensitivity for appraisal of these abilities and therefore can be employed for clinical assessment in calculation and number disorders.
