Digital calculation was one of the important cognitive actions in daily life. Recent neuropsychological and behavioral studies showed that calculation may be done based on the language process. This study aimed to observe activation of functional areas related to verbal working memory in digital calculations with block-designed fMRI experiments. Subvocal number reading, simple and complex calculation experiments were preformed on healthy volunteers. Our results showed that verbal working memory was not necessary for subvocal number reading, but was even necessary in dealing with simple arithmetic problem, and verbal working memory had the loading effect during calculations.
