This inquiry answers the question “How do computers do math?”. What once started as an innocent question from a six year old, turned into this 9 page post.

After a short introduction, we dive down into solid-state chemistry from where we emerge traversing along Ohm’s law, semi-conductors, logic gates and combinational logic.

The first seven chapters answer of our inquiry. Chapter 5 and 6 are optional. The remaining chapters merely complete the discussion of logic gates.
