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.

Coert, I have tried to make a square root in excel but it would be work. The multiply and divide work in excel and the CSM works. I can not send you a picture of my work in this system. Can you help me?

Thanks. I think the sqrt schematic might use the q* instead of the q to build the new subtrahend.

I worked around the problem for now. Please let me know if it works for you. I also published the companion article that implements the functionality using an FPGA:
