LOGIC LAWS - DISCRETE MATHEMATICS

[@Trevtutor]

Check out my new course in Propositional Logic: trevtutor.com/p/master-discrete-mathematics-propositional-logic It comes with video lectures, text lectures, practice problems, solutions, and a practice final exam!

[@byunbaekhyun4010]

Schools definitely forget the importance of hiring good teachers. Give your students AT THE VERY LEAST a good math teacher. My professor literally just showed us slides with all the laws and then gave us statements telling us to solve them. When we asked how it was supposed to be done, he said to only look at the laws and then for sure we'd get it. We didn't even know what the laws meant. He could solve the problems, but COULD NOT tell us how. Considering the fact that he was pretty young, it sucks having to fill in his gaps. He just couldn't tell what the laws meant, he literally just told us to LOOK. Seems pretty petty this comment, but it frustrates me so much how I've learned more in the 15 minutes it took me to watch this video, than the 4 hours we've spent with him. Thank you for this video~

Byun Baekhyun I know your pain man

[@lucas_gane]

North American education system is very flawed, their goal is only to get money from students and many professors do not care as well.

[@azforthlol]

That's the classic maths teacher mistake. Many gifted mathematicians think in an extremely visual way, but they are horrible at expressing that understanding as language. Trev is an excellent tutor because he clearly understands the relationship between raw visual data and language very well, evidenced by the linguistics courses on this channel.

[@meowmix-t7n]

As a self-centered former philosophy major, I will say that we don't put a lot of importance on philosophy as a country. I always assumed myself to be terrible at math, and then I was required to talk formal logic to get my degree. I almost dropped the second degree because I was TERRIFIED of this class. Ended up with a 106 on the final and a predilection for programming. It's amazing. Not everyone learns the same and because you might struggle with math, it doesn't mean you struggle with logic.

[@Jakob-Odman]

Sadly this is the exact same reason im watching this video.

[@swag-yw7ut]

my professor took a whole week in total to explain all of this and I couldn't comprehend it at all. This man just took 15 minutes to get through all of the laws and made me fully capable to solve any logic laws questions I come across. You are a lifesaver, TrevTutor.

[@محمد-م5ث1ش]

Actually, When I saw that the video is just 15 minutes, I had a feeling that it's not complete

[@bryllpadasas5618]

Probably, our brains are haven't fully developed that time.. 😂 My professor left an assignment that he hasn't discussed yet. That's why I am here and I am so glad that it's easy to understand. 😁

[@moonlover2022]

If he would teach you this in 15 minutes, would not you report him, since you are paying lots of money to university. Hey mate, don't compare uni vs youtube.

[@ua2894]

maybe the cute girl sitting 2 seats away was too much of a distraction?

These are the best Discrete Math videos I have ever come across.

[@burakbeyy216]

... I have ever came across.

[@pink221]

Your teaching is incredible! So far just from these videos alone I have learned all about Truth Tables, Set Theory and Propositional Logic in just a couple of weeks. Straight to the point without jargon and easy to follow. I'm sure others agree :)

[@zacharychapman3732]

Thank you so much. I’m taking an online class with no lecture, just a textbook, and it does not explain these things clearly at all. You helped so much. I’ll be back to watch the rest of these I’m sure!

[@mustafamalik4211]

The distributive law example with 3x(2+1) was genius. I am able to remember it now. Thanks!

[@samk1267]

honestly I thought i'd never understand logics but thanks to you i'm so confident now.God bless!

[@SpookyCatto]

Starting my first sem of CS, he explained it better in 15 mins than my lecturer in 2 hours

[@byunbaekhyun4010]

oh my god i'm actually learning.

[@jepale2]

Holy crap dude. you really made it simple, I just learned so much more than i expected to watching this video. Your teaching style is great

[@dresscheme2940]

Jesus Christ man you're a lifesaver. I couldn't understand other people's shenanigans, this is my 8th video regarding this topic and I have my exams in the next 2 days. Thank you so much

[@OhDoze]

I may have had to watch this video 10x....HOWEVER, it is finally coming together. One step at a time. Thank you!! -Visual Learner

[@rubendias6241]

Damn, its crazy how I was trying to learn this for so long, and now I just learned how the rules work in 15 minutes. I'm starting to like math.

[@lila6120]

I and my inability to focus on anything for more than 20 min thank you for this. No, really, I'm glad I can still learn things even if my depression-induced mental block makes me lose it in class, stare blankly, panic... Just... thanks. I really appreciate it, dude.

[@alfarq]

Dude, thanks alot. You gave me the ability to succesfully use these laws.

thank god I have watched your videos and I am getting better understanding about this logics of law. It is so much better than my lecturer who is trying to explain in class for 1 hour and 30 minutes and he also cannot understand what he is talking about, and his handwriting skill is so messy until I cannot even know what he is writing. Anyway, thank you for coming out these kind of videos!!

[@dabarago]

easily the best video I've watched on logic laws in discrete maths. Thank you.

[@ntgc-tv]

TheTrevTutor you are indeed the savior... Am just still wondering why some teachers will simply complicate topics and subject to make them so scary and frustrating to understand... Million thanks to KZbin and TheTrevTutor

[@jamesnowitzki9930]

Thank you so much man !!!!!! i thought i will not ever understand my class lecture but thanks to you i can understand them now ! i thought i cant learn my current class lecture because im not good at mathematics in preschool and highschool. I'm in college now and i'm really interested in math because of you ! i didnt know that it feels so good learning something math related. Thank you

[@thedeathofbirth0763]

Those who know do, but those who understand teach. Trev , you are an awesome prof! Can you do a master class for my teachers on how to teach?!

[@walanjo3818]

imma need to binge watch this playlist. we had 2 seatworks and i'm pretty sure i got both 0. your videos are absolutely helpful so thanks. keep making

I thought this topic would never be interesting, you proved me wrong. for the first time I'm actually enjoy learning logic

[@aboutthereality179]

Hi There. Thank You Trev for the patience in explaining clearly and step by step this simplification of formulas. God Bless.

[@thegalacticgamer4592]

In logic statements where you have to determine whether or not something is true, what does "such that" and "one has" mean and what's the difference between them?

[@rownitasheikh8343]

The second distributive law does not follow the arithmetic operations .a+(b*c) is not equal to (a+b)*(a+c)

[@henryzt]

THIS IS MUCH BETTER THAN UCL'S LOGIC TEACHER

[@bryllpadasas5618]

As a college student I love the perspective of having a self study. But because of this, some teachers are seem so lazy to teach or discuss their lessons. Lucky to those who are resourceful.

[@selviaanggun4278]

Thanks a lot. Really helpful

[@Revanth292000]

At 9:51, when you use the absorption law on the right side logic, why's it p? Why couldn't it be (P and Q)?

[@Makwaje]

YOU ARE THE BEST!

[@yusufcaglar99]

thank you so much such a great education video luv ya

[@meirbookatz8304]

Trevor at 8:20 with the absorption law is it only when the ^/v symbols are different inside and outside the brackets? or does it absorb for any combinations of and / or?

[@meathead1469]

13:57 Hey, why did you use distributive law instead of abosportion law? Diffeences between distributive and abosrtion is: the values withn the distributive is different but the values within the abortion is the same as the outside value

[@phamvankhoa6117]

You save me... Thank you so muchhh

[@johnnynguyen4134]

Thank you sir

[@anzefajfar3072]

why did the brackets stay in the last case? Doesn't de morgans law remove brackets? So after that you get: not p or not q and q, but then and needs to be resolved first, which means ~ not p or 0

[@zaylo9273]

By the way, do we put or the triple line while writing the laws?

[@carment5567]

Trev could you please make a video explaining the DPLL procedure/algorithm in logic for satisfiability??? I'm really having issues trying to understand it and I cannot find any decent video that makes it simple enough to understand... I would really appreciate it and I'm sure tons of other people would as well.. Thank you in advance I hope you receive this comment!!!

I did the second one a little bit differently: ~(~p^q) ~~(pvq) .DeMorgan's Law pvq .Double Negation Is this still legit? Or do the laws go only one way?

[@rainermayagma1778]

~(~P)→ (P v (P^R)) 1. P → (P v (P^R)) Double Negation 2. P → P Absorption Is this right?

[@gravityhamster8805]

Why is it that in DeMorgan's law you distribute the NEGATION but then you have to flip AND to OR and vice-versa, but when you use the distribute law you don't have to flip AND to OR and vice-versa?

[@QuiteTheBrianD]

Very good video, man. Finally starting to understand this shit
