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
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
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
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
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
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!!!!
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.
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.
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
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.
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.
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. 🤘👍
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.
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
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.
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.
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.
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.
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.
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!
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.
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.
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!
JESUS CHRIST all the other tutorials were so complex especially my professor's teaching. BUT THIS, THIS VIDEO IS SO EASY TO UNDERSTAND omg thank you so much
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.
HEY BRO!THANK YOU FOR THIS TUTORIAL BUDDY, I HAVE JUST STARTED THE JOURNEY AND YOUR EXPLANATION MAKES ITS VERY EASY.I AM NOT LEAVING YOU TILL I COMPLETE THIS UNIT.
This is the clearest and best video I've seen on truth-tables so far, and I've checked out a lot of others. Thx for sharing. You've helped me a great deal.
Thank you SO much for this video. I was struggling with this topic in my honors Geometry at my brand new prep/boarding school. This video got me a hundred on my test, and I am very grateful.
This is how I know I am not a genius. A genius can read my Logic book for class and understand what the heck it says. I have have to YT this, and I am having the hardest time with this class. Thank you for simplifying this. The text in the book is too hard to undertand.
This video is the BEST explanation by far! I have not been in school since 1999 and I started college again in 2018, you really have a great way about explaining math and I personally thank you for uploading.
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.
WOW!! I watched this one time and caught on so quick. Been listening to my instructor and it was like wtw are you talking about! Thank you for these video!!
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!
You did a great job explaining this.. I just failed my first exam… this info was on it and I thot I knew it… I guess not..I’m going to watch this video again and again until I get it cemented in my head!!
I literally love you! You explained this so well! I - you're amazing! I hope you know that my professor couldn't even help me understand this! I hope you're doing well whoever you are. Thank you thank you thank you!
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 .

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.
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
So it’s only false if the condition is negated?
It's asking to write a T if either Q or -P has a T in that column.
bruh this is so straight forward and simple i nearly cried
Freaking me to. Me too. Like it’s the best for someone who thinks logically.
I did cry
RIGHT
true its a T bro
I’m lost
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
yessss i should have youtubed it forever ago lol
I felt that frustration on a spiritual level omg
i’m telling you, on the brink of breaking down.
Omg!!! Learned more in ten minutes than in a week of logic class. 🎉
Yea... ME TOO!!
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
Just got my results and I got a 92. This is honestly the best video ever made. Thank you thank you thank you!!
@@angeldo8546 omg 92 😱😱 wowwwwwwww
omg samee
@@angeldo8546awesome! Congrats on your exam!!

THANK YOU SO MUCH!!!!
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!!!!
Please hang in there… don’t quit!!! Keep pushing yourself…even if it’s baby steps, keep pushing yourself.
the most straight forward video on this topic
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!
I feel u
Sense*
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.
the little funny add-ons (hell yeah, not even close, etc.) really keeps me interested wow cant believe how much this helped me
I was struggling with this for 3 hours and decide to RUclips truth tables and this video helped me understand it in 6 mins !!!!!! Thank you!!!
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.
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
I literally learned this concept in 11:38 minutes to help my friend THANK YOU. THIS IS AMAZING
I nearly cried today because we are having a quiz today. during my quiz I just watched your video it helps a lot.
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.
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.
I almost threw my computer at the wall trying to learn this stuff until I came across this video. God bless you.
half of the stress is out of my head thanks to you
We understand that you are there for us. You don't have to cuss Big Brother❤ God bless you!
this is the MOST simplistic way of explaining. THANK YOU MATH GOD.
Literally the best explained viedo i ever come across, thank you so much!
I've been in near tears all evening until I found this. Light at the end of the tunnels at least now. Thank you!!!
My professor, TA and textbook couldn't explain this. You explained this beautifully and I understand now. Thank you.
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. 🤘👍

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.
Yup, that sounds perfect, good job!
Understood it in 10 mins than a 3 hour lecture by my prof lol. Thank you.
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!
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
You speak the way I think! You just saved me with this explanation. Don’t change anything about the way you present.
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 !!!
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.
thank you for this i was struggling to understand this for the past week
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
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.
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.
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!!!
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

oh my god you just explained in 11 mns and secs the things that I cant understand in 2 days ...THANK YOU SO MUCH
Learned more from this than I ever will this semester
Absolute LEGEND! The most helpful and best explanation you will ever FIND!
I just threw down my pencil before I watched the video and now I can actually do my assignments. Thank you so so so much.
very helpful. i liked the color coding and that you didn't get bogged down in details and kept it simple
this video might actually be sent from Heaven. thank you for explaining truth tables so well!!!
dude, I've been watching 50 videos, yours is the best. You made it easiest way to understand. Thank you
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!
This man is the real MVP. Thank you so much. You made this so simple.
thank you so much this helped 1000000x then my professor ever did
this is so helpful! I struggled in my undergrad logic class and this is a great simple way to explain it!
i just want to thank you for making this video. i have homework due in 1hr and 30mins and i might be able to finish it because of you
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!!!
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.
this is by far the best explanation of this topic that i have seen
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.
Love the color visuals! You explained it better than the book, thank you!
Today is the day I learned that my professor can't teach. Amen.
😂😂
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!
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.
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!
You make truth tables so much easier! I think everyone should watch this video while learning this subject! Thank you so much!
This helped me so much!!! Thank you!!! You explained it much simpler than my teacher did. She made it so confusing!! Appreciate you!
DUDE, thank you!! this was spot on helpful, quick, and super informative
You have changed my life.
mid study sesh and was stuck on conditional statements, this helped a ton! thank you for your service
Wow! to think I passed this video because several others missed the mark. Thank you for that clear explanation!!!
This is the best and thorough explanation that I’ve found, keep up the good work!!
JESUS CHRIST all the other tutorials were so complex especially my professor's teaching. BUT THIS, THIS VIDEO IS SO EASY TO UNDERSTAND omg thank you so much

This is the ONLY video that actually helped me understand this goddamn table. Thank you so much 😭😭
Thank you, I've had a mental block about these things and this helped get rid of it
"Is there a T in each column? Hell yeah there is." This is the energy teachers need.
HEY BRO!THANK YOU FOR THIS TUTORIAL BUDDY, I HAVE JUST STARTED THE JOURNEY AND YOUR EXPLANATION MAKES ITS VERY EASY.I AM NOT LEAVING YOU TILL I COMPLETE THIS UNIT.
This is the clearest and best video I've seen on truth-tables so far, and I've checked out a lot of others. Thx for sharing. You've helped me a great deal.
Thank you SO much for this video. I was struggling with this topic in my honors Geometry at my brand new prep/boarding school. This video got me a hundred on my test, and I am very grateful.
thank you for helping with my computer science hw
I've been struggling with this sm. I even read over my notes what felt like a hundred times - but your video explained it so much better!
This is how I know I am not a genius. A genius can read my Logic book for class and understand what the heck it says. I have have to YT this, and I am having the hardest time with this class. Thank you for simplifying this. The text in the book is too hard to undertand.

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
watching this one video, made everything crystal clear. THANK YOU FOR MAKING THIS VIDEO !!
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
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.
ThAnks for the video. I was starting to understand when I came across your table and your way of making students understand this. Thanks !!
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.
WOW!! I watched this one time and caught on so quick. Been listening to my instructor and it was like wtw are you talking about! Thank you for these video!!
bro this video explains way better than my teacher
ABSOLUTE LEGEND, understand so much better now, thanks so much
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!
This is the best vid out there explaining wtf a truth table is
You did a great job explaining this.. I just failed my first exam… this info was on it and I thot I knew it… I guess not..I’m going to watch this video again and again until I get it cemented in my head!!
2:23 is me realizing I messed up the entire table.
You are my hero! I understand now because you said you are looking for ts and you have to earn ts. Thank you!
I’m going to cry because watching this one tutorial would’ve removed all my unnecessary pain and hardship
Thank you! thank you! thank you!, you are a star, I have watched many videos and I did not get anyone who explains it clear like the way you did
Very explanatory...Now I understand clearly 😍
The best tutorial on this so far...
I literally love you! You explained this so well! I - you're amazing! I hope you know that my professor couldn't even help me understand this! I hope you're doing well whoever you are. Thank you thank you thank you!
this was very straight forward and easy to learn. THANK YOU, now I understand
