Why does it seem like such a monumental effort to do moderately complex arithmetic in one’s head?
Our brains are not designed for serial calculations, which is what a math problem is. A complex math problem is an extremely serial calculation. You have to do part of it before you do another part of it, and so on, until all the steps are completed and you get an answer.
The Short Answer
Our brains are not designed for serial calculations, which is what a math problem is. A complex math problem is an extremely serial calculation. You have to do part of it before you do another part of it, and so on, until all the steps are completed and you get an answer. Our brains are REALLY good at massively parallel "rough" calculations. For example, we can look at a face, and quickly identify the person based on ALL the little features being compared to what's in our memory, ALL at once. For example, you dont *have* to compare someone's left eye to what's in your memory BEFORE or AFTER you compare their nose, Lips, hair, etc. This means that your brain can split up the task into TONS of little tasks, and do it very quickly. Meanwhile, computers struggle to do really quick facial recognition, since they're better at serial tasks, rather then parallel ones.
