As a software developer I imagine the brain not as some separated layers but as a huge collection of routines/procedures, for this or that (including procedure for understanding numbers), interconnected with a spaghetti code of links. Many of these processes specialise in making decisions and calling other processes. One specialised procedure is called the consciousness, it is blind to the rest of the processes and it is tricked into believing that it does all the calculations while it merely reads the results from other processes. Also, I highly recommend the book The Language Instinct by Steven Pinker.
