ugh. i hate that we're using a slash for negation instead of a turnstile, tilde, or even exclamation point. I'm going to confuse it for a slash between two premises.
Might be jumping the gun here, but is it safe to say that negating is useful for categorical arguments? Like if the argument is
All cats are sad. Garfield is a cat, therefore Garfield is sad.
The negation of sad would be unhappy, neutral, etc. which would allow other members of the cat set to feel a wide range of "sad-adjacent" emotions? Could very well be overthinking this and might hit myself later for even making this comment :-)
Yo so i took a practice test and it had the phrasing un- like unhot or unwashed is this enough to go on to say it's equivellent to not or what are yall's thoughts
How do you know when its necessary to use Negation and when its not necessary?

is the use of lawgic just to help us piece through items on the test, or will we actually be seeing this methodology on the LSAT?
So cold would just be one type of negation, because it's included in not hot?
it is super freaky to be in discrete math and see all of the same rules apply in my LSAT studies...
this lesson unlocked something for me -- I feel my brain growing!!!!
Is my use of Lawgic accurate here?

Will we ever be dealing with opposition?
Cake or not-cake?
I jokingly said, "not rich" to negate rich, and I got it right, haha!

From a more mathematical perspective…
Negation is distributive, and when the negation acts on ANDs and ORs, they switch.
Example:
Let’s assume our financial state is one of these four:
Rich
Comfy
Poor
Broke
Rich is then logically equivalent to (could be replaced by):
not comfy AND not poor AND not broke
So then, NOT Rich is logically equivalent to:
not (not comfy AND not poor AND not broke)
Using the distributive property of the negation (just as a negative multiple is distributed through parenthesis) and the AND to OR rule…
Not Rich = comfy OR poor OR broke
Assuming we can only have one financial state at a time, we can clearly see that the negation of Rich is not poor, but any other state besides Rich.
this is just the joke that everything in the world is either a salad or not a salad

So a similar rule to Negative Comparatives in that it opens the door to multiple possibilities as opposed to one clear answer?
Correction: Padawans are Jedi (members of the Jedi Order), but they're just not Jedi Knights (who are required to pass the trials). you're welcome :0

I thought the opposite of hot was chopped
Everything in the universe is either a potato or not a potato.
Is this a negation, a true statement, or valid statement?
(I was sort of joking when I began this comment, but now I'm genuinely wondering.)
Hardest example for me to perceive so far: Jedi....
This helps me better understand the Disney question from earlier
Isn't the negation symbol:
¬
Please tell me if this is wrong or right?
The slash negation symbolism is making my formal logic phil background go insane
As a software dev, I loathe that / is used for negation rather than ! (bang).
do we need to know the importance of the language like the / even though I will be taking the test after August and do not need to know logic games?
