Computer Math
Binary, hexadecimal, boolean logic and the IP address arithmetic every operator ends up doing on a napkin.
What you'll actually learn
Binary and hex aren't academic trivia here — they're the actual arithmetic behind a subnet mask, a permission bit, and a color code, and this track builds the mental shortcuts operators actually use instead of reaching for a calculator every time. Boolean logic gets the same treatment: not abstract truth tables, but the exact reasoning behind a firewall rule or a search filter.
What you'll be able to do
You'll be able to look at a CIDR suffix or a chmod number and convert it in your head fast enough to use it in a real conversation, without opening a calculator — the specific, unglamorous fluency that separates someone who looks things up every time from someone who's actually comfortable with the numbers underneath the job.
