Is there a mathematics area, or which areas solve a sum in your head?

There is no single mathematics area; several networks share the work. The horizontal segment of the intraparietal sulcus represents quantity (it is active whenever two numbers are compared), the left angular gyrus retrieves facts learned verbally such as multiplication tables, and the posterior superior parietal lobe moves attention along the mental number line. The dorsolateral prefrontal cortex holds intermediate results in working memory and plans the steps, and the anterior cingulate cortex catches errors and conflicts along the way.
