// processors.
//
// The Problem: 
//  We have a lot of numbers that need to be math'ed. Doing this on one 
//  CPU core is slow. We have 4 CPU cores. We would thus like to use those
//  cores to do math, because it will be a little less slow (ideally
//  4 times faster actually).
//
// The Solution:

Writing your own OS to run on a handmade CPU is a pretty ambitious project, but I've managed to get it working pretty well so I'm going to write some notes about how I did it.

The correct way, install homebrew on apple m1.

# We'll be installing Homebrew in the /opt directory.
cd /opt

# Create a directory for Homebrew. This requires root permissions.
