Natural Deductive Logic: RULES #2 (vI, vE, DN, RAA)

[@FlexThoseMuscles]

If anyone is wondering the justification for line n at 3:45. It's not k-l but l-m.

I’m wondering why you didn’t just take care of c in line 5, based on it being another potential modus ponens? Is it because you wanted to specifically demonstrate the new rules?

Thanks for the video!

Is there another name for reiterate? (R) Is that what CP is (Conditional Proof) or is that a different rule?
