I need to write a formal proof to get the conclusion: ¬A ? ( ¬B ?...
I need to write a formal proof to get the conclusion:
¬A ? ( ¬B ? A) ? B
I am not allowed to use TautCon or AnaCon.
I can use proofs and subproofs and I have to declare the rules and what lines to cite.
I was given no premises, just need to get the conclusion, and I am super confused.

Proof 6.20 Language Proof and Logic
Premises: AvB, AvCConclusion Av(B^C)I don't even know where to start with this one. I need some guidance. On an overall structure.The only line I have is (AvB)^(AvC) ^ intro but after that I am completely lost.Any guidance would be appreciated.This is a fitch-style formal logic proof. Only can use things like contradiction elim/intro, v intro/elim, ^ intro/elim, and negation elim/intro.
