That's me, a degree-holding full time computer scientist, just learning arithmetic I guess.

Bonus question: what even is subtraction? I'm 99% sure it doesn't exist since I've never used it, I only ever use addition.

Addition by the additive inverse.

Now you just replaced one incalculable thing with a different incalculable thing.

Eh?

Computers don't subtract, and you can't just add a negative, a computer can't interpret a negative number, it can only store a flag that the number is negative. You need to use a couple addition tricks to subtract to numbers to ensure that the computer only has to add. It's addition all the way down.
