Abstract: New advances of research on brain science of calculation indicated that the simple mental calculation re?鄄ferred to the arithmetic facts retrieval directly, and relied on the language areas of the left hemisphere, but complex mental calculation activated the left parieto-frontal network and the bilateral inferior temporal gyri, which were related to the visuospatial representation and visual mental imagery. The exact calculation revealed a large and strictly left-lateralized activation in the left inferior frontal lobe, however, bilateral parietal lobes showed greater activation for approximation than for exact calculation. Besides, the brain activation during calculation was influenced by the age, individual differences in mathematical competence and training. The findings gave some implications for the development of child calculation competence.
