Logic - Fitch-style Natural Deduction Proofs #18-23

[@oscarfm2954]

Thank you so much dude, math teachers typically get a bad rep but I would be so happy to have u as my teacher !!

Wish more teachers and profs were this good at explaining the basics. We would have so many more good mathematicians and less burnt out students.

I agree that I am SO GOOD and should be famous. Billionaires, please get in touch directly so I can tutor you in formal logic for mere millions of dollars.

@@dodecahedra I think billionaires are too busy exploiting the working class to get in touch, sorry!

Here's my proof of #18:
1. A → B : Premise
2. ~B : Premise
3. ~A ∨ B : 1, MI-Rewrite
4. ~A : 3, Weak LEM
