Boolean algebra #4: Different terminology and notations

visit www.keleshev.com/ for tutorials and extra materials on Boolean algebra and digital hardware design!

[@parampatel3108]

i love that he started with simple ones and then worked up to the harder problems, he teaches so much nicer than my actual professor!

[@morganbeukes8518]

you're good at simplifying a whole chapter into a few minutes that would have taken me hour or hours to study....GREAT WORK

[@aboudramlawi100]

U r the best. but I think there is mistake, u said (A.B) = A or B and (A+B)= A and B but I guess it's the opposite (A.B)= A and B (A+B)=A or B right?

[@keno104]

+Aboud Ramlawi correct. but turn on your annotations since he made some

[@sikharoy1646]

Exactly

[@funmeister]

i was just going to comment the exact same thing. A.B is "and" while A+B is "or". my annotations is off, so didnt realize he corrected it there.

[@reljoy]

How do you turn annotations on? I can turn on auto generated subtitles but annotations sound different.

[@moazelsawaf2000]

Yes, you are right 👍

[@M_VERICK]

Your videos are still being watched in 2020, you're a legend.

[@fr3aky742]

BEST C++ teacher ever saw on the INTERNET ! Bro, Please do videos on Class & Objects and Inheritance too :D !!!!

[@baonguyen-hz6cb]

THANK YOU SOOO MUCH! i wish you were my professor! i got more out of your videos then weeks of lectures!

[@Epsil0nify]

You were the reason that I passed my midterm! Best Boolean algebra tutorial ion the Internet!

[@mixxamm]

6:19 should be AND. I know there's an annotation, but they're getting removed later in 2019. (and also are not visible on mobile)

[@mixxamm]

And 7:50 should be OR

[@shazalb482]

Vlad 12 years later and im using this video amazing bro your better than my University teacher lol

[@patricewhite175]

YOUR VIDEOS ARE AMAZING!!! THANK YOU FOR THE SIMPLE EXPLANATIONS AND CLEAR PROCESSES!

[@barnibussnaples6561]

Your whole series is very helpful for my class. My class doesn't explain any of this very well, but you make it make sense.

[@graysoneasterling3000]

Using these to help me with my UIL Computer science team. Loved the videos!

[@mobryan1976]

Thanks Vladamir for these videos! You explain this much better than my class professor.

[@marcolcal]

Vladimir thank you. You explain everything so swiftly!! Great Teacher.

[@TheAhernFamily1]

The upside down carrot at 6:47 should be the opposite direction to be an "AND" statement I believe.. in that position that looks like a "V" is actually an "OR" statement i believe.... if i'm correcto!?

[@alekdanser]

+Aheezy Da Islander Yes,you're right /\ means and, \/ means or

[@rudgreen5958]

The Ahern Family you are right. The teacher had a slight mistake there . Glad you noted that. May God's grace be with you.

[@babyRess_Gaming]

I noticed that as well, that should be and AND logic

[@snow7912]

u just save my life for dld this semester..thanks alottt the best explainations and very clear... cant help but subscribe after 3 videos

[@danijelumicevic3213]

hahah same here

[@roykimani3482]

Your videos make boolean algebra enjoyable. keep it going sir from Kenya Africa

[@acdxrkocskarmy]

Thanks, Vladimir ! So, nicely explained. I am now clear about these basics. . . .

[@tadhgire]

just want to say that your videos are amazing :) i was looking at khan academys website but he has none, then I found yours and was happy to see the teaching is just as good :D

[@mattzeitler4476]

You're a great teacher. Very easy to follow.. You're structure of teaching this is excellent. My instructor made this hard when it's quite simple honestly... It just takes basic understanding of polynomials to simplify. Anyways he jumped into it in a weird way, but you nailed it. Just gotta say that appreciate you so much! I should of paid you instead of my college, but gotta have that slip of paper.

[@soupanimationstudio420]

THANK YOU VERY MUCH.IT WAS VERY EASY TO UNDERSTAND WITH YOU THEN HOW MY PROFESSOR EXPLAINED IT..THIS WAS VERY HELPFUL FOR ME 1-4 VIDEOS

[@jaydogg9933]

Thank you Vladimir this is helping me with my Digital Electronics course a lot, you are the man!

[@dialavagwendhal9699]

Thx a lot for your explanations It really helps a lot Would be lost without you

[@ehoihere]

Thank you very much for this video! I encountered some unusual notations of not A and was so confused. Now this makes sense!

[@kennycuadra4408]

I appreciate your videos so much, they helped me a lot, much love from Las Vegas 🙏

[@joebrady9829]

These videos are great! They are very easy to follow and understand. I think this should definitely be the first video though. I was very confused what was meant by multiplication and addition in the first three before I looked it up

[@amazingbait26]

Currently in a course where the teacher is Asian and just flips through the slides without really teaching anything; these videos taught me in 10 minute segments what she could not teach me in 3 50 minute sessions.

[@DenisTheMenaceMMA]

Thank you very much for your videos... I have course "Logic systems" this semester its all about your videos and our lecturer makes it so impossible to understand... you just made my life easier.

[@hemitasawant9003]

it is really very good ,it helping me for preparation of board exam keep guiding me

[@arjunsanjay412]

man u just saved me!!! got better in my exams man... thnx man...

[@rio3724]

thanks Vladimir was really helpful

[@666bikes]

thank you very much for these videos. you have now replaced my digital logic professor!!

[@drewgraham1482]

Just wanted to say Thank You. These videos were helpful and very well done.

[@awolff138]

Thank you. I wish I had you for my lectures.

[@sulmazz]

Hi Mr. Keleshev thank you so much for your videos. They are very very useful to me !! because I can not memorize the rules I would rather understand them and that is what your videos provide me with

[@gregssmartphone4296]

Great videos, clearly explained and at a good pace. Many thanks

[@ramuzamakhammetsheripova6509]

I would like to know whether we can use this strategy in solving such problems : Five travellers P,Q,R,S and T came from five different countries (Algeria,Belgium, Canada, Denmark and Egypt not necessarily in the same order) to visit the country of Pantina. They each flew on a different airline out of V,W,X,Y and Z (not necessarily in the same order). As all the five travellers were staying at the same hotel they met up at the hotel café and were discussing which country they were from and which airline they had flown in on. At the end of their discussion the following information was available. • T is not from Canada • Q is not from Egypt • The airline that the traveller from Canada flew on was not X • The airline that the traveller from Algeria flew on was neither V nor Z • Travellers P and Q both are not from Canada or Denmark • Travellers P and Q both did not fly on either airline W or X • S is not from either Algeria or Egypt • The traveller who flew on airline W is neither from Denmark nor Canada • Neither R nor T flew on airline V or W and neither of them is from Belgium or Egypt???

[@budhachandrayumkhaibam6079]

2017 and still useful.... Data never age

[@moon-ia2068]

thank you so much sir , you really helped me and made the boolean algebra so easy

[@BlackBearTexas]

Thank you for this video series, it's helping mean learn the concepts for my digital logic class

[@aidank91]

Sir, thank you very much for your videos, they have helped me extensively.

[@Runnable19]

even if you help only 1 person that would be enough.

[@TheDsheffer]

Also the sign you used ("^" upside down, I believe is called a wedge) is for "or". The sign that would be used for "and" is the "&" (ampersand).

[@kissoonmm5940]

good job!! i appreciate your work... Thank you, you've helped me tons!!

[@TriyanshaB]

They are super helpful, College life saver!

[@gersimuca]

That is true :D my life is saved for tomorrow :p

[@VincesEngines]

Your tutorials are really good thanks for sharing

[@cynthiaespinoza8438]

Vladimir you are amazing! Thank you thank you

[@bassplayingchris]

Enjoying your videos, thanks!

[@MINIAWARFR]

not all heroes wear capes

[@jamelpelapel5727]

I learned more in this video thank you sir and I wish that you were my professor

[@tresurehammer2027]

thanks a lot for your teaching style and effectiveness ...wish you add more logic maths.......there are a small errors of notificaciones concerning v and inverse

[@BorderEdge]

the logical conjuntion(AND) symbol is supposed to be : ∧ and the logical disjunction(OR) symbol is supposed to be: ∨ You have them switched. Otherwise, great videos! keep it up.

[@anthonybeervor2265]

Thanks! I'm applying these methods for my sociology research!

[@03333628261]

Your videos are very help full!

[@hashfromjc]

Your videos are super useful.

[@sikharoy1646]

A.b is and gate. A+B is or gate. To check, 0.1 = 0 and 1= 0 If it was or...answer would be 1, isn't it??

[@watchout3762]

I like your videos and I learnt a lot from your videos

[@aeramkhan97]

thank u so much fr these videos ! they are helping me alott

[@bensoneobabueki7824]

Thanks for your videos. They are very useful. However, I noticed that OR and AND were somehow mixed up in #4.

[@keleshevCOM]

@freestylerstyler Glad to hear that! Hope you have fun with it ;-)

[@mmkid444]

Thanks for the help in Digital Logic! this is soo helpful!

[@Nudepushups]

Great videos! Thank you, they have really helped me understand the subject.

[@shwetadeshmukh4141]

Sir there’s a mistake in this video A.B is multiplication ie AND A+B is OR

[@ophelielune8392]

SO the upside down U and V represent the Negative form of the variables?

[@james77011]

At 6:22 A•B is not the OR gate, that is the AND gate. A+B is the OR gate

[@manbill6130]

thanks for the teaching it helps a lot

[@blz1rorudon]

Good Day, sir. I think the " ^ " is for the logical AND and the other one is for the logical OR

[@MultiMrfrost]

thanks for the videos they where a lot of help for me :)

[@elijahglenn4902]

Hi Sir, I have been quite impressive about your tutorials, thanks a lot well done. However Sir, there's something I did not understand from this video lecture. You called plus in logic as AND and multiplication OR instead. I thought it should be verse versa?

[@jaysongrace6399]

These videos are amazing. Keep it up!

[@KurmaTejendra]

a and b = a.b , a or b = a+b this was indicated wrong in the lecture b

[@msparthgupta]

u r gr8 thank u very much for all ur videos...

[@ustatvofficial]

8:46 your logical notations are wrong

[@TacoDaddy-mr8ig]

At about time 6:19 when u wrote A*B its actually pronounced A and B nor A or B. The OR is for addition and represents the OR GATE multiplication represents the AND GATE

[@mohammedalghamdi8804]

I learned a lot from you. Thank you very much!

[@jennytt8121]

finally i know how to do this. Thanks

[@nashilongondengu2425]

thanks Vladimir totally helpful

[@MrRayne911]

ha ha my lecturer did this in two lectures which are four hours, and i didnt get it. 40 minutes here and i get it clear as sunshine

[@itechvally]

thanks it was very good approach

[@Beachpapa2010]

Thank you for the help.

[@ParoXsitiC]

Your logic symbols ∧ and ∨ are mixed up. You can remember it by the ∧ seems to want to form an A, for AND.

[@colehayden5089]

Thanks for the help.

[@sidmanyshots]

Thank you! It has helped me so much!

[@pkmakhafola1]

Great explanation

[@menardkatavare9854]

very helpful thanks vladimir

[@drkshad0w89]

great videos, helps alot

[@fidelpecout2289]

Thank you very much.

[@EstronkaS]

what if I have, notXY + XnotY How to simplify this?

[@Trooooond]

thank you for mixing AND and OR ...

[@tw10262]

Why is their no subtraction?

[@WolfsArrowSG]

I love you thank you now I know makes me so happy

[@tharushikavindi8888]

this a.b is a and b. not a or b. a or b = a+b

[@VernCrisler]

Hi Vladimir, great videos. However, I think you should redo this one.

[@robertjacobperkins]

You are great man

[@sanketbhushan8661]

Thanks 🇮🇳🇮🇳
