Regions with significant activation and deactivation elicited by contrasts of AT > NT and ST > NT. Threshold was set at p < 0.05 voxel‐wise with FDR correction and cluster size >10 voxels. Abbreviation: AT, addition task; ST, subtraction task; NT, number matching task; IPS, intraparietal sulcus; pDLPFC, posterior portion of dorsolateral prefrontal cortex; FFG, fusiform gyrus; FEF, frontal eye field; SMA, supplementary motor area; AG, angular gyrus; ITG, inferior temporal gyrus; PCC, posterior cingulate cortex; mPFC, medial portions of the prefrontal cortex; L, left; R, right; BA, Brodmann area
