How does etching a specific pattern on a piece of silicon make it do math?
I’m probably wrong on this assumption, please correct me it that’s true.

At its most basic level it is just a series of switches, in this case, transistors, and with transistors you can make logic gates, Think of logic gates like special switches that control electricity in a circuit.
They take in one or more signals (like “on” or “off”) and use these to decide what signal to send out. It’s kind of like following simple rules to turn things on or off.
These are logic switches, so you can make configurations like:
* NOT Gate: Flips the signal (on becomes off, off becomes on).
* AND Gate: Needs all inputs to be on to turn on.
* OR Gate: Needs at least one input to be on to turn on.
* NAND Gate: Opposite of AND, turns off if all inputs are on.
* NOR Gate: Opposite of OR, turns off if at least one input is on.
With the billions of transistors you find in computers, you can make very complex logic systems with these simple building blocks of switches.
