I had a teacher 2 years ago who told me that computer processors only know how to add values. That you need to tell them how to substract, divide, and multiply by programming.

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. See the FAQ for guidance on how to improve it.

You can create a CPU that only knows how to sum and then derives everything from that, but modern CPUs use additional operations such as shifts as well as tables for expensive operations such as division in order to run at high speed. | |||
