jjf28 -- with one giant truth table
[12:20 am]
Dem0n -- How the fuck do you prove (p -> q) -> ((p v r) -> (q v r)) is a tautology?
[11:40 pm]
Dem0n -- oohhh that's true
[11:40 pm]
jjf28 -- does implication have a distributive property? or more importantly, has your instructor provided a rule stating so?
[11:34 pm]
Dem0n -- Am I seeing this wrong, or can (p -> q) ^ (p -> r) and (p -> (q ^ r)) just be proven by distributing p to q and r in the second statement?

jjf28 -- and yes, another notation xD
[11:20 pm]

[11:16 pm]
Dem0n -- Oh my god I actually figured it out
[10:59 pm]
Dem0n -- But they specifically ask for me to prove equivalency with logical properties
