Introduction to Logic: Statements, Negations, and Quantifiers

[@j0hnnyboi1]

I was able to fully understand this lecture in 22 minutes than 50 minutes with my Math for Liberal Arts professor. Thanks for making this video public!

I really liked your scheme. Thank you. What I am looking for is how to negate "either.. or" statement ? Can you please explain?

[@joshuaguillemette5632]

@Sunny, either/or is most likely an OR function.
p = I go to the store
q = I go get gas
either I go to the store or I go get gas
p OR q
no, this may be a way of denoting an exclusive OR, an OR where both cannot be true but I would need some more context.
An exclusive or is usually noted as XOR and has a truth table:
p q p XOR q
T T F
T F T
F T T
F F F

This has helped me understand negation on the LSAT so much. Thank you

Hi I just wanted to say thank you for posting your videos. I took my exam last week and passed!! I couldn't have done it without your videos!! Thank you again for taking the time and posting them...BTW I'm a nursing student and the exam I'm referring to is the Contemporary Math exam for Excelsior College.

Excellent job on explaining in grave detail, good examples, and easy to understand! A HUGE help! thanks!

i can't see the link for the slides.
i think it the explanations are great but the visual is a little bit unclear.
that's why it would be great to get those slides.

[@lashawoods2933]

ok, the only thing puzzling me is how to know if something is true or false, for example "William Shakespeare wrote the last episode of The Sopranos." if I new nothing about Shakespeare how would I identify it as true or false? is it based on common knowledge? also I am asking this for test purposes.

[@BossChronicles]

Yes for philosophy and law

Thanks this was very helpful!

[@qixue6233]

What if the case is "some students do not love green"? Is its negation is "No student do not love green"?
