Boolean Algebra 1 - The Laws of Boolean Algebra

[@MelodyLiuJade]

Please tell me you teach for a living! Your lectures are easier to follow than any professors I've taken.

[@ComputerScienceLessons]

I have been a teacher for most of my working life. Either in schools, or training software engineers. I am currently Head of Computer Science in UK school. Thanks for the lovely comment. :)KD

@@arjay_2002 So he's still knowledgeable on the topic

[@utility507A]

I couldn't agree more. I'm doing a digital electronics course right now, and this single 15 minute video cleared up all the confusion my professor has caused in the past two weeks. I have mid-terms coming and this lecture series is going to save me. Thank you so much!!!

[@Jechob]

The textbook for my computer hardware class is entirely white page/black text, no color, minimal diagrams. Made it very hard to get boolean logic and algebra down. This video has already taught me so much more than the book did 3 weeks into the semster. Thanks a ton!

[@ComputerScienceLessons]

You are very welcome. I was the inadequacies of the majority of the textbooks out there that prompted me to make these videos. Having said that, I do like the A level computer science textbooks by Heathcote and Heathcote.

[@JayJay-ki4mi]

I've got essential computer mathematics, practical discrete mathematics and concrete mathematics for computer science. All 3 are dry. After watching this video, and revisiting the textbooks it all made sense. Maybe I'm a visual learner.

[@mawataksmara6653]

Hi Jachob, I need assistant for my digital class

[@marksladen2901]

This is fantastic. It's amazing what proper preparation and presentation can do. This obviously wasn't just banged off in a spare 20 minutes at the end of a day. I really appreciate the work you put into this. Trying to read the material and coming across something like 1 + 1 = 1 for the first time confused me, but you cleared it up with no doubts as to what's going on. Thanks a million!

[@ComputerScienceLessons]

You are very welcome indeed. Thanks for acknowledging the time and effort. :) KD

[@thatonellamawhoissoobsesse8138]

I kinda see it as math involving the description of nouns through numbers -1 being closer to "one in the presence of one" than "1-1=0" Theres a name for this type of information under statistical sociology being descriptive/representative data instead of a variable data (integers gathered for data) idk :) just rambling, this is my first video on boolean algebra

[@DerynCullen]

Having locked maths away in a dusty corner of my brain about 30 years ago, I now find myself needing a serious bootcamp as I teach myself coding and software development. Your videos are an absolute godsend - just head and shoulders above every other resource I've looked at. Thank you so much!

[@iamrising7176]

What have I been watching? Whaoooo! I hit the subscribe button 3 minutes into your first video. The voice and explanation...Whaooo! Thanks sooOOoooOOOOooo much.

[@ComputerScienceLessons]

You are most welcome, and thank you :)KD

[@dk3153]

im from germany and its really hard to find good material on all of this, been struggling with my homework and didnt really know what to do but your calm and collective way of explaining things really helps. presentation wise perfect. what a blessing

[@tanveerahmad8455]

Your lectures are easier to follow than any professors I've taken. Exactly Thanks Sir God Bless You

[@ComputerScienceLessons]

You are most welcome. Delighted to help :)KD

[@katekuhl6115]

Many thanks for the excellent series of videos on Boolean logic, I've been using these with my A-level classes over a number of years and found them very valuable.

[@ComputerScienceLessons]

Delighted to hear it. Thanks for commenting. :)KD

[@johnk9173]

This is one of the most succinct explanations I've found on the topic. Thank you, for the great tutorial!

[@ComputerScienceLessons]

You are welcome. :) KD

[@HamedAdefuwa]

this is one of the best explanations of anything I've ever come across. I've been doing electrical engineering for 5 months now and only just come across your channel. Subbed! Thank you!

[@ComputerScienceLessons]

I'm delighted to hear it was useful. Thanks for the great comment. :)KD

[@dercap325]

I am sort of late to the party but i still felt the need to praise you for this video, you've done a great job. I had absolutely no idea about logic gates etc. beforehand but got everything after these 15 minutes

[@ComputerScienceLessons]

That's really nice to hear. Thank you :)KD

[@uniquebharat789]

Thanks from Bharat I left this topic because single distributive formula which is given in wrong in my book now I corrected this it saved my time a lot thanks sir

[@laurants]

I appreciate the simplicity of the name of the channel.

[@thedardanitan]

Brilliant video sir. Really well explained. I've been stuggling with grasping A2 Boolean Algebra laws because our teacher was rushing the topic too fast, and our Computer Science A level coursebook hardly explains it in such detail...

[@ComputerScienceLessons]

Glad to help :)KD

[@TheRaspberryPiGuy]

I'm at the University of Edinburgh, and I wish our lectures and tutorials were even 10% as clear as your videos. Thanks!

[@sleep9514]

Thank you, this is making much more sense now. Started JavaScript, from there had to understand Boolean algebra. For a person who always struggled with any kind of math this is making sense.

[@naseef2075]

Studying for an ICT exam tomorrow, these videos are really helpful.

[@ew4nnn]

this is making online uni so much more manageable, thank you so much good sir! :)

[@swafly]

People like you make Math and Computer Science bearable for people who cannot understand logic fast enough like a lot of people do. It takes me hours to figure out how a concept works and so videos that explain it in simple terms make it extremely helpful for me to understand these topics. Math and Computer Science is more fun when we have people like you, Ben Eater, Neso Academy, The Organic Chemistry Tutor, and many other amazing people. Thank you for this series and all the other videos you have put out!

[@excme22]

[@jeffreyohler2599]

To the host of CS,I say Thankyou for taking me to class. This is the first of your vids I've watched,I Believe. Yet I'll be watching more for sure!!! *Subbed*

[@ComputerScienceLessons]

You are most welcome :)KD

[@motazfawzi2504]

I'm not sure if this can be considered algebra but I believe it is. *S* is for *Step* 12:24 (A+B) * (A+C) *1S1* : = AA + AB + AC + BC {In binary A squared (A*A) is equal to A, so replace it} *1S2* : =A + AB + AC + BC {In addition I can place parenthesis anywhere} *1S3* : = (A + AB + AC) + BC *1S4* : = A(1 + B + C) + BC {In binary any thing plus one is equal to one. So (1 + B + C) = 1 ... (A * 1 = A)} *1S5* : = A + BC And we are done! Edit: 13:06 A * (A+B) *2S1* : = AA + AB *2S2* : = A + AB {Same as *1S2* } *2S3* : = A(1+B) *2S4* : = A*1 {Same as *1S5* } *2S5* : = A *3S1* ... {Start from *2S2* and continue}

[@faridgulum1226]

[@taekwondotime]

I've found that the *absorption law* is the most difficult one to spot. Thankfully, once you learn about K-maps, simplification becomes a much easier and less error prone process. :)

[@ComputerScienceLessons]

For me, the biggest problem is knowing when to stop. K-Maps are definitely more conclusive.

[@luthfahood4093]

Such a useful video. Thank you so much. I can go and explain Logic gates to my Y10 Computer Science group

[@ComputerScienceLessons]

Thanks for the comment. I'm not sure I would go this far with ALL of my Y10 class (writing expressions from simple gate combinations is usually enough for mine), but many would benefit from an insight into this.

[@MotiviqueStudio]

This helped visualize the text I'm using so well. Thank you.

[@fud0_0]

what an easy to follow break down! thank you

[@fg1307]

Great video! Clear and very useful. Keep going

[@MyWissam]

6:57 I don't understand why in Boolean addition 1+1 =1. So, it is not addition mod 2. Is it just the desired definition to correspond to what we want to represent, in this case an OR? I just noticed, if we follow a mod 2 arithmetic, so that 1+1 =0, then we get XOR.

[@other39201]

I'm a beginner but I think I have a good way of thinking about it: If we think of 1 or TRUE as just any random voltage and 0 or FALSE as no voltage at all - we can say that NO VOLTAGE + NO VOLTAGE = NO VOLTAGE (0+0=0) and that SOME VOLTAGE + SOME VOLTAGE = SOME VOLTAGE (1+1= 1) So basically 1 just represents SOMETHING and 0 represents NOTHING and when you add SOMETHING with SOMETHING the answer will always be SOMETHING :)

might be a silly question but how do you know what input values goes on the truth table?

Not a silly question, but fundamental. Take a quick look at this video: kzbin.info/www/bejne/eJ-lY6Bno72NbpY The idea is to include all of the input possibilities. :)KD

I'm not sure if anyone mentioned but the distributive law only works for multiplication with base 10 algebra, this had me very confused as I like to compare for understanding.

[@jabril3d476]

[@Rahul-fq9kf]

You you suggest a good book that is as good as your explanation in this video. I need to clear many more concepts such as that of Conditional Statements. There is no video I can find where you have covered that concept. Thanks.

How can this be? B V ( B ^ C ) = B ( If we dont have truth table)
