Principia mathematica should not be used as source book for any actual mathematics because it’s an outdated and flawed attempt at formalising mathematics.
Axiomatic set theory provides a better framework for elementary problems such as proving 1+1=2.
Tl;dr is that a legendary mathematician wrote in a margin of a book that he’s got a proof of a particular proposition, but that the proof is too long to fit into said margin. That was around the year 1637. A proof was finally found in 1994.
One part of the 360 page proof in Principia Mathematica:
Friggin nerds!

It’s not a 360 page proof, it just appears that many pages into the book. That’s the whole proof.
Weak-ass proof. You could fit this into a margin.
Upvoting because I trust you it’s funny, not because I understand.
It’s a reference to Fermat’s Last Theorem.

I thought it must be sonething like that, I expected it to be more specific though :)
I’m not believing it until I see your definition of arithmetical addition.
