I cover some Logic Games posted on TrevTutor’s official instagram () from Sep 27 2021 to Oct 9 2021. This can be used as basic prep for the LSAT or just for fun! I’ll post one of these videos for every 5 logic puzzles I make!

Hello. Can you answer this?If Bill is older than Tom and Tom is younger than Sally, then who is older between Bill and Sally?
Dude, I would love to see you post more of these. The education of many students is woefully inadequate in basic logic and deductionary skills. This is really important stuff, and I am so glad to see it. I hope you're able to do more.
Funnnn 🤩
nice
I have a question that might be too basic for anyone to care to address:
a proposition is a statement about how things are, like p: "John is a dog",
that proposition can be True or False, i.e. it can have the truth value True or False,
if it has the truth value True, then that means that it is True that John is a dog,
if it has the truth value False, then that means that it is False that John is a dog.
So, my question concerns negation… does negation merely FLIP THE TRUTH VALUE assigned to a proposition, or does it do something else?
I'm wondering because… I often hear things such as "we have a proposition, like "John is a dog", and the negation of that proposition just means that "It is not the case that "John is a dog"".
Sure, off the top, that makes perfect sense; it's not the case that John is a dog. Ok cool. But, what if "John is a dog" (p) were False? I mean, I know what happens; if we negate that whole thing, then John becomes a dog again. But, my point is that negation here seems to sort of change the proposition itself. Negating "John is a dog" only becomes "It is not the case that "John is a dog"" IF it was TRUE from the beginning that John is a dog. But if "John is a dog" were FALSE from the beginning, then the negation of "p" would mean that "It is not the case that it is not the case that "John is a dog"", right???
What I'm asking is, is it strictly speaking incorrect of people to say things such as "propositions are statements, like "John is a dog", and the negation of that statement means that "It is not the case that John is a dog""? Because what they seem to be doing is ASSUMING THAT THE STATEMENT IS TRUE BY DEFAULT. So, isn't the strictly correct way to put it then instead: "the negation of p means that "It is not the case that THE TRUTH VALUE of "John is a dog""?
TLDR; Does negation flip WHICHEVER truth value a proposition has, OR does it add "it is not the case that" in front of a proposition? It seems that if the latter alternative is the correct answer, then the proposition is just assumed to be true, because if we have a proposition p: "John is a dog", and if the negation of p translates into "It is not the case that "John is a dog"", then p is assumed to be true, by default. And if the negation of p when p is false translates into "it is not the case that it is false that "John is a dog"", then that would seem like a special case, because if it isn't a special case, then negating a true p would have to be "it is not the case that it is true that "John is a dog"" instead of simply "it is not the case that "John is a dog"".
which program do you use to record your videos
For the last puzzle (six professionals, 3 musicians, 3 artists) I think that we do not need the following two pieces of information:
T is in a different profession than S.
If P is an artist then so is U.
I think that we can solve the puzzle without them.
i dont know if im not searching right or anything else apart from that but please add more topics to your channel especially in discrete math like correlation and regression…… i learn better from you so if you don't have videos of a specific topic on your channel i find it hard to do it anywhere else
I have a question for you.
How can I ask them to you?
