Hey I understand how to do this but the only thing that I don’t get is Why exactly is the conditional statement true whenever p is false . I understand the statement is only dealing with when P is true .. q should be as well... but when p is false ... how can we guarantee that p implies q... hopefully you understand my question haha thanks

[@larryquinn543]

Brian Stonelake hey I appreciate the reply ! I think I’ve thought of a different answer let me know what you think about it . So I also realized that just because p and q are both true , in the real world it does not mean that p implies q. You could just have a situation where p is true Independently of q. So the way I reconciled this was thinking of it in more mathematical terms as in “does it satisfy the condition “ so if p is true and q is also true , it does indeed satisfy ‘if p then q’ because when p is true q must be true for this to work . And when p is false , any truth value of q would work because the condition only concerns when p is true .. and the point of these truth tables is only to decide validity , not soundness so in a way some of the Ts can be thought of as place holders as in we’ll call it true since it does not invalidate the argument . When you think about it the only situation that would truly invalidate ‘if p then q’ is specifically when you have p but q is false . Haha that’s my thoughts on it

[@infinitusfinitus]

oh thank god someone put it into words! this was my sticking point too. I thought I was just dumb because I skived maths in high school.

[@satanggukie3456]

I personally find this difficult to explain also but I believe it is this way: Since the condition is already false, there is no more condition for the q so it is independent. It becomes “vacuously” true nonetheless since Q is true

[@beedlethebard1813]

So it’s only false if the condition is negated?

[@Xemi_]

It's asking to write a T if either Q or -P has a T in that column.

I genuinely want to sob, I wish I could like this a million times, I cant believe this frustrated me for a good few hours when this 11 minute video exists lmao

[@porc3lain_7]

yessss i should have youtubed it forever ago lol

[@_little_byrd_-0v0-]

I felt that frustration on a spiritual level omg

[@_mxonlight_5909]

i’m telling you, on the brink of breaking down.

[@Norcalmiller78]

Omg!!! Learned more in ten minutes than in a week of logic class. 🎉

[@astrickland897]

Yea... ME TOO!!

[@redcrossman9014]

bruh this is so straight forward and simple i nearly cried

[@lidyasolomon5557]

Freaking me to. Me too. Like it’s the best for someone who thinks logically.

[@angeldo8546]

I have a mid term in ten minutes, and I’ve watched about four other videos. This has definitely been the most straight forward and actually most helpful one. thank youuuu

[@angeldo8546]

Just got my results and I got a 92. This is honestly the best video ever made. Thank you thank you thank you!!

​@@angeldo8546awesome! Congrats on your exam!!

[@jonrk2]

I really struggle with math, I ALWAYS have. College math (the most basic class) isn't easy for me due to me having poor math skills and having a not so great professor. I've been stressing out over truth tables for the past week and I've had no help from the professor and was about to give up...this video finally helped me make sense of this whole concept. THANK YOU SO MUCH!!!!

[@caroljaymes3880]

Why can’t teachers teach like this??? Why do they have to get so complicated??? Just bc some people are teachers doesn’t mean they should be!!!!

[@caroljaymes3880]

Please hang in there… don’t quit!!! Keep pushing yourself…even if it’s baby steps, keep pushing yourself.

[@saraholmes5183]

This makes so much since now! My teacher didn’t explain it this way, and I was struggling on my math homework. Now I get it! Thank you!

[@yunyun6352]

I feel u

[@umauma9160]

Sense*

[@BrooklynnMarieVids]

This has helped me tremendously, and I was just starting to think that no one could explain truth tables to me. I appreciate that you were able to break it down and explain every column.

[@nieshapurter8168]

I was struggling with this for 3 hours and decide to KZbin truth tables and this video helped me understand it in 6 mins !!!!!! Thank you!!!

[@mariamramirez1875]

You're a live saver!!!! I had a mental breakdown this week because I couldn't understand the way my teacher was teaching me but this was so straight forward and simple... you're amazing

[@silvermora6918]

Since everything is online; I clicked through my sessions blindly. Watched this before the test. Makes WAYYYY more sense. Thank you for explaining so simply.

[@lachimolalacarbonara6393]

I literally learned this concept in 11:38 minutes to help my friend THANK YOU. THIS IS AMAZING

[@DandKGames]

There's always that point where everything clicks and you finally understand the topic. Thanks! Explained it better than my teacher, or maybe I was asleep, either way thanks.

[@silviealvarado]

omg THANK YOU- online student here and what I was reading was NOT making ANY sense.3 hrs of not understanding later, i find your video and it just clicked. THANK YOU.

[@Gurleee]

oh my god you taught me so much in 5 minutes! i have a computer science exam tomorrow so this is very helpful. thank you sooo much. i love you lol

[@IrishPaladyn]

from the bottom of my heart, thank you sir. I genuinely was having an anxiety attack welling because I couldnt understand what my professor was saying when they taught us this.

[@phathisanincube3185]

the most straight forward video on this topic

[@chuarex1077]

After thousands of scrolling on youtube tutorial about Tautology, this video makes the most sense. It so easy to understand than different tutorials spread on youtube. I commend you dude, you're very good. 🤘👍

[@attria4945]

the little funny add-ons (hell yeah, not even close, etc.) really keeps me interested wow cant believe how much this helped me

[@chinwenze-ky2ff]

Thanks alot you are the best. My teacher actually expected us to cram and memorize the table but I thank God that I have been able to understand the topic well

[@9cowbell9]

Understood it in 10 mins than a 3 hour lecture by my prof lol. Thank you.

[@Wospwosp]

My professor, TA and textbook couldn't explain this. You explained this beautifully and I understand now. Thank you.

[@sydneyjustin1446]

I have been struggling over this for weeks and this finally helped me reach some clarity. Thank god because my test is in 4 hours!

[@ryiamariepigueras3381]

I nearly cried today because we are having a quiz today. during my quiz I just watched your video it helps a lot.

[@γιωργοςγιωργου-η6ξ]

one night before my logic exam and i was ready to give up on figuring out how this table works. AND THEN I FOUND THIS VIDEO. You are my savior !!!

[@james-lr2le]

I started learning discrete math this semester, and I have no clue what is going on with the truth table. After watching your video, I had an "ah ha" moment, and everything clicked. Thank you, I really like the way you simplify things to a more understandable and more digestible learning experience.

[@Delulumileslover]

I’m going to cry because watching this one tutorial would’ve removed all my unnecessary pain and hardship

[@Cyphon]

Thank you so much! I literally couldn't get the hang of it in any other tutorial but now i understand if it's "or" or "and" you have to look for the T.

[@catperson776]

Thank you so much, I am taking a philosophy class and needed to make a truth table, you are the only person to actually explain it well to me

[@makellingo]

I've been in near tears all evening until I found this. Light at the end of the tunnels at least now. Thank you!!!

[@pakkawadeeatchley365]

dude, I've been watching 50 videos, yours is the best. You made it easiest way to understand. Thank you

[@klcross2010]

You speak the way I think! You just saved me with this explanation. Don’t change anything about the way you present.

[@therandommushroom2922]

This lesson has been taught to me before but when I reached college, I forgot it all. I tried to watch some videos relating to truth tables for a recap and finally understood your version than my teacher ever taught to us. Thank you, really.

[@tequestabraswell8877]

I had difficulty trying to understand the logic, but Brian you explained it in a simplified way. Math haven't been my strong point but it made more sense when you went step by step. Thank You!

[@dargful]

this is the MOST simplistic way of explaining. THANK YOU MATH GOD.

[@zionthomas6871]

We understand that you are there for us. You don't have to cuss Big Brother❤ God bless you!

[@jacqueslin8178]

I'm taking a philosophy course. I wasn't able to understand my professor's lecture but I understood this perfectly. Thanks for the simplification!!!

[@mirielagonzalez-kaganac4562]

this is so helpful! I struggled in my undergrad logic class and this is a great simple way to explain it!

[@benchpressguy]

Teacher went through the truth table chapter in September. Now it’s November and every week we’ve done new stuff mixed with review and truth tables always come up. Tried, tried and tried and it just didn’t click. Now after watching this video it clicked. The if then finally makes sense it’s way simpler than it seems. Thanks so much.

[@YuNgHaSaN]

Absolute LEGEND! The most helpful and best explanation you will ever FIND!

[@shoocakadoo]

I wished I had watched this earlier. Your explanations are so simple and relatable. Either the teacher or website will explain everything in math terms and symbols which makes the whole thing so overblown complicated. Sadly, I have a math exam in like two weeks, but this seriously has helped my understanding a lot.

[@shadiegoddie2663]

I actually thought for a minute I was to halfwitted to even understand this until I watched this video bro ...this is fucking great.

[@jahnj2523]

Aye Bae I need a tewter u finna help me out?

Another great math utube instructor is Tyler Dewitt!!! Math and science I think!!!

[@hopeelizabeth6859]

very helpful. i liked the color coding and that you didn't get bogged down in details and kept it simple

[@jeanneb5130]

OMG thank you so much! My professor went over this so many times and I was so confused.... Four hours in class was a waste, he should've just put this video up.

[@djw1185]

This is world class explanation for me. I was struggling with understanding the P implies Q part of truth tables. But they way you explained it, 10/10. liked and subscribed and i will be sharing with my uni friends.

[@mindofty266]

After watching like 5 other videos including my own professor’s this finally helped me understand truth tables and even more complex tables than this.

[@SD-uw7zu]

I have finals coming up in a few weeks and this really helps. You made it so simple and my teacher honestly doesn’t know what he’s doing

[@lachimolalart]

This is the first truth table tutorial I've watched, that ACTUALLY explains how T/F is determined per column. Thank goodness, finally! Thank you!

[@angelinakays343]

omg this is amazing! THANK YOU! I nearly cried when i saw my assignment this week. I'm still confused about constructing a truth table for the statement for my problem but i at least understand truth tables now!

This helped me SO MUCH! You described everything perfectly and helped clarify all my questions that I had, especially with the if, then scenarios. Also, you went at the perfect pace for me to follow along. I'm a college student, so I really needed this help and it's greatly appreciated :))

[@crunchberrychaos1545]

Much appreciation, good sir. My anxiety is down about 80% after looking this up. I have an exam this week and I been "faking it till I make it" with truth tables. Now I can actually make it.

This is the best vid out there explaining wtf a truth table is

[@rino7213]

You have changed my life.

[@lmcdasm]

Dude.. your video is the best breakdown on the internet (watched 8 and i got it, but your explanation of when its "contrapositive" and how its "always logically true" kicks ass!

[@Henry-vq3gz]

"Is there a T in each column? Hell yeah there is." This is the energy teachers need.

[@alfabetony]

ThAnks for the video. I was starting to understand when I came across your table and your way of making students understand this. Thanks !!

[@hannahcruz1428]

I am so thankful for this video. I am reading straight from the book and could not understand how they got T or F to start off with. Thank you!!!

[@fayy.m.1342]

Wow! to think I passed this video because several others missed the mark. Thank you for that clear explanation!!!

[@yukicchi95]

This is the ONLY video that actually helped me understand this goddamn table. Thank you so much 😭😭

Me too lol

[@jessicalira1069]

Thank you so much, I had been struggling with this the whole week. The way you explained it makes so much sense- thank you again:)

U really just saved me I was about to drop this class even though I needed on this journey to nursing school

[@Xerinnicole]

I almost threw my computer at the wall trying to learn this stuff until I came across this video. God bless you.

[@alexa.2403]

man, i nearly lost my mind when I first studied this on my own, but with your help kind sir, this just became easy as pie

[@erikatorres309]

I thought I was going to fail my math class because of these truth tables now I understand them a whole lot better. Thank you so much for this video.

[@georgia-leesmith3595]

this video might actually be sent from Heaven. thank you for explaining truth tables so well!!!

[@marinewife12201]

Thank you for making this video it has helped me. My professor did not add the -P, -Q columns on the truth table he had us finish but had IF NOT q then NOT p. So I think by watching your video using the contrapositives for IF p then q, to IF NOT q then NOT p will help me get my answer since they're the same. Hopefully I understood this right.

[@LearnYouSomeMath]

Yup, that sounds perfect, good job!

[@Petite43]

watching this one video, made everything crystal clear. THANK YOU FOR MAKING THIS VIDEO !!
