Wow, I understood the whole concept behind conditional statements and got a clear picture of how to represent them into truth tables just in 11 minutes. Thank you
I don’t know what it is but when I read this stuff in a book I get it but I don’t really start locking the information in until I watch your videos or just videos in general about a topic. Thanks for being a great teacher!
Mr. Organic Chemistry Tutor, thank you for explaining the difference between Converse, Inverse, and Contrapositive Conditional /Biconditional Statements, Logic and old fashion Geometry. This is a classical start to writing basic proofs in Mathematics and classes that uses logic.
Hi, I'm from Kenya.I really appreciate you for always making educational videos personally they help me alot when i've not understood a concept in class
Nicely done. Nice voice-over. Simple; to the point. No fluff. No rigamarole, and believe you me I know rigamarole, as I've encountered a lot of rigamarole in my life! 🙄
We're having online classes due to COVID, and our professor gave out this link. I'm in university taking up my premed, and youtube videos are more helpful LMAO. Thank you for substantiating what I have understood.
I was a PHYSICAL Science major student last year, but know I'm a computer science major at the University of Johannesburg, you still helping. Since high school precise.
The hypothesis and conclusion can be called antecedent and consequent respectively Conditional statement is an implication statement where can be written as "If p, then q" Biconditional statement can be written as "p if and only if q"
I dont have a teacher to teach me,we do modules and learn by ourselves...It sucks,all your teacher basically does is send you work.some of them wont even answer questions you ask em many times...now,Im hella struggling
How? How you made videos on all topics I need? I am not a chem major student but you mde videos on calc3, ochem, and computer logic!!!! YOU ARE AMAZING!
...i was kinda finding Converse is the reverse of conditional, and contrapositive is the reverse of inverse, so this means the converse of inverse is contrapositive
It is like multiplication and division Converse(Inverse) = Contrapositive So if you multiply this by Inverse again, you are basically doing... Converse(Inverse)(Inverse), which just equals converse.
Converse would be: If an angle is obtuse, then it is 94 degrees (which is false) Inverse would be: If an angle is not 94 degrees then it is not obtuse (which is false) Contrapositive would be: If an angle is not obtuse, then it is not 94 degrees (which is true) not sure if he mentioned in vid, but the converse and inverse are always the same: Either true or false. In this case they are both false. Same goes for both the original statement and contrapositive. In this case they are both true. This is called equivalent pairs. Biconditional would be: If and only if the angle is 94 degrees, then it is obtuse (this is false). *also, if the converse is true the biconditional is also true)
Hello my Teacher this topic is very nice and thank you so much Next can you make another video on quantifier this topic is very difficult to understand??
The LA/CA examples very clearly have a true/false to them, but what about the truth statements for the pizza examples? Conditional statement: "If I am hungry, then I will eat pizza", I'd say false, as I could eat chips if I was hungry. Converse: "If I eat pizza, then I am hungry", wouldn't say true or false, sometimes I eat pizza just because it's there in front of me. Inverse: "If I am not hungry, then I will not eat pizza", again I wouldn't say true or false. Contrapositive: "If I won't eat pizza, then I am not hungry", should have a same as the conditional, so it should be false, which I'd say is right, maybe I don't eat pizza because I don't like it. So then the Converse/Inverse should be true, but they don't sound true.
I know this is late but for others wondering: It depends on what actually happens , will you eat pizza? will you not eat pizza? are you hungry? are you not hungry? P = I am hungry Q = I will eat pizza Consider CONDITIONAL: "If i am hungry, then I will eat pizza" Case 1: You are hungry, you will eat pizza (Conditional TRUE, you will eat the pizza if you are hungry like you said you would) Case 2: You are hungry, you will not eat pizza (Conditional FALSE, you lied: you said you will eat pizza if you are hungry) Case 3: You are not hungry, you will eat pizza (Conditional TRUE, you never said you must eat pizza only if you're hungry) Case 4: You are not hungry, you will not eat pizza (Conditional FALSE, you didn't say you will eat pizza even if you aren't hungry) ------------------------------------ So now consider the CONVERSE: "If i will eat pizza, then I am hungry" Case 1: You will eat pizza, you are hungry (Converse TRUE, you are hungry and so you decide to eat the pizza, matches with what you said you would do) Case 2: You will not eat pizza, you are hungry (Converse TRUE you are hungry sure, but you aren't hungry as a *consequent* of eating pizza like the converse states) Case 3: You will eat pizza, you are not hungry (Converse FALSE - you lied: you said you would be hungry if you eat pizza) Case 4: You will not eat pizza, you are not hungry (Converse TRUE - as you aren't hungry as a consequent of *not* eating pizza, you are hungry as a consequent OF eating pizza) ..And so on with inverse, contrapositive (do the truth tables yourself)

WHY IS DAT EVERYTIME EXAMPLES ARE SO EASY BUT THE HOMEWORKS ARE HARD
well you have to practice it then the video will not work if you don't do it
You
Yes you
Remember
Fuck you
You are right
You have to remember the process/how to solve it. Not the examples
Yeaaa... so true.....idk how teacher find out the hardest questions ever that didn't even exist

My favorite UA-cam tutor ever! The Organic Chemistry Tutor > Khan Academy.
I'm just genuinely curious of how this guy would definitely ace all courses in college that is related in engineering, computers, and science.
My math teacher is blowing my mind... He is very very fast..... But u are the best teacher

Your videos are the only educational videos I can tolerate! Thank you.
The EXPLANATION is amazinggggg.... couldn't have found better explanation than this....🎉 Thanks 🙏
You explain it so we’ll and slow so I can actually learn
The Last example was very understanding.
Thank you very much.
I really love your tutorials they have helped me alot during this tough moments thank you so much
Love your videos. You explain everything so clear
excellent explanation
Yes the videos from 2006 are helping
pleasant day sir. I just want to really thank you cause your videos and explanations have been helping me out for almost 3 years now .
i never skip ad for you
@@roxxonmetric8021 you don’t get it, if you don’t skip the ad, then the creator of the video gets money.

I was a PHYSICAL Science major student last year, but know I'm a computer science major at the University of Johannesburg, you still helping. Since high school precise.
Thank you so much. Your lectures better than many college teachers.
Nice work
Hii i am from India . And i am really thankful to uh 👍👍
Net only have this guy helped me in two grades his voice is also so nice to listen to
Wow this is like common sense taken mathematically i love it😘👌
THANJ YOU SO MUCH, I’M REVIEWING FOR MY GEOMETRY TEST, I OWE YOU.
I totally got this. Thank you so much! you saved my grades
This guy is amazing explaining these concepts
I recently found this channel a few days back and it has helped me so much!!! Thank you 😊
Didn't understand the lecture,came back watched this video, understood it fully.
I always comes back to your channel and enlightens me how you discuss it so well rather my teacher and even professors discussed it to me.
When they literally remove the numbers in math
nah
Thank you for these videos!
The hypothesis and conclusion can be called antecedent and consequent respectively
Conditional statement is an implication statement where can be written as "If p, then q"
Biconditional statement can be written as "p if and only if q"
Played it on 2x speed with captions on, thank u bro, my exam is tomorrow ❤
thank you this helped me a lot
Best math tutor ever
Wow this guy has carried me through college. The only thing he doesn't have is Programming tutorials.
I think the organic chemistry tutor is better than my real professor.
I studied for many years in school and i only learned everything in this youtube channel
ty undertand much more
Appreciate so much your effort for the explation
You've been of so much help to me. Thank you.
thank you for this i can answer my homework now.
thank you so much for this, it helped me understand 1,000% better
Very nice, what about the people that live in Los Angeles, Spain? That was meant to be a touch of humor.
If i can't sleep then i should hearing this man talking *it's because his voice calm my thoughts and i don't know why
can you do predicates and methods of proof please!!!!
Thank you so much my teacher can’t teach -_-

Thank u. U help me understand way better
write contrapositive of if x
Your the man dude you helped me out insanely incredible 🙏🙏🙏🙏
thank you so much for this, this actually helped me understand my math lesson!!!
this feels like if then or cause and effect in grade 3 english lessons
This whole channel is an actual elite university.
How? How you made videos on all topics I need? I am not a chem major student but you mde videos on calc3, ochem, and computer logic!!!! YOU ARE AMAZING!
I have maths exam after few hours.hope This will help a lot
Thanks mate.
Thank man
taught it better than my geo teacher, thx
We wanna see you. we only know your voice and you teach everything perfectly. are you not a robot?
never been more confused
Hi can you please upload a video about truth tables thank youu!
Sir Upload some videos of discreet structure about ( using laws of logic simplify the statement form)
...i was kinda finding Converse is the reverse of conditional, and contrapositive is the reverse of inverse, so this means the converse of inverse is contrapositive
It is like multiplication and division
Converse(Inverse) = Contrapositive
So if you multiply this by Inverse again, you are basically doing...
Converse(Inverse)(Inverse), which just equals converse.
Thanks, i learnt again
If an angle is 94 degrees then it is obtuse ? Which would be converse , inverse , contrapositive , biconditional ?
Converse would be: If an angle is obtuse, then it is 94 degrees (which is false)
Inverse would be: If an angle is not 94 degrees then it is not obtuse (which is false)
Contrapositive would be: If an angle is not obtuse, then it is not 94 degrees (which is true)
not sure if he mentioned in vid, but the converse and inverse are always the same: Either true or false. In this case they are both false.
Same goes for both the original statement and contrapositive. In this case they are both true. This is called equivalent pairs.
Biconditional would be: If and only if the angle is 94 degrees, then it is obtuse (this is false).
*also, if the converse is true the biconditional is also true)
You made it very easy to understand man, thanks!
Hello my Teacher this topic is very nice and thank you so much
Next can you make another video on quantifier this topic is very difficult to understand??
THANK YOU KING YOURE SO SEXY your simple explanation of converse=reverse, inverse=negation, and contrapositive=double negative was enlightening my guy
You are a hero!
Hello
Does this video have continued?
Any other videos on elementary logic?
Can you do a video on a general idea on how to answer questions on proof in mathematics
In which class would you learn this?
Awesome 😊👍
I really do love all your videos sir
God bless you for sharing this it was very helpful 🙏❤️❤️❤️
So does this topic relate to the Law of Detachment and Law of Syllogism?
Love you man🥰
Can you please do more discrete maths videos
Thank you so much!

So then the Converse/Inverse should be true, but they don't sound true.
Had the same question for 2 weeks
I know this is late but for others wondering:
It depends on what actually happens
, will you eat pizza? will you not eat pizza? are you hungry? are you not hungry?
P = I am hungry
Q = I will eat pizza
Consider CONDITIONAL:
"If i am hungry, then I will eat pizza"
Case 1: You are hungry, you will eat pizza (Conditional TRUE, you will eat the pizza if you are hungry like you said you would)
Case 2: You are hungry, you will not eat pizza (Conditional FALSE, you lied: you said you will eat pizza if you are hungry)
Case 3: You are not hungry, you will eat pizza (Conditional TRUE, you never said you must eat pizza only if you're hungry)
Case 4: You are not hungry, you will not eat pizza (Conditional FALSE, you didn't say you will eat pizza even if you aren't hungry)
------------------------------------
So now consider the CONVERSE:
"If i will eat pizza, then I am hungry"
Case 1: You will eat pizza, you are hungry (Converse TRUE, you are hungry and so you decide to eat the pizza, matches with what you said you would do)
Case 2: You will not eat pizza, you are hungry (Converse TRUE you are hungry sure, but you aren't hungry as a *consequent* of eating pizza like the converse states)
Case 3: You will eat pizza, you are not hungry (Converse FALSE - you lied: you said you would be hungry if you eat pizza)
Case 4: You will not eat pizza, you are not hungry (Converse TRUE - as you aren't hungry as a consequent of *not* eating pizza, you are hungry as a consequent OF eating pizza)
..And so on with inverse, contrapositive (do the truth tables yourself)
