Ok so I understand how this is different from the other thing we learned where A--> B turns into /B-->/A, but how does this compute for my notes? Like in which cases do we use both of these? Why would I be doing a negation like in this video?

I'm confused, I don't know which one is the conclusion they all seem like premises. Saying something revealed something would be evidence to make a later claim, no?

I don't understand how a lot of these are making sense, specificially the part about "and" v "or". For example, doens't Q4 require BOTH parts to be true? if it doesn't ensure that other people are safe, how can it be a self driving car?

I don't get why H--> LSD if its saying that ONLY IF LSD is synthesized we get Heroin. wouldn't that mean that LSD--> H???

i don't get the difference between the "if" statements and the "only if" statements. one part has to exist to lead to the other part in both cases
