Thanks... I've been a systems engineer for 25 years and never actually understood the purpose of 2's comp until you mentioned the hardware implementation.
An excellent explanation... very clear. I highly recommend both Parts 1 and 2 to anyone wanting to understand the basics of two's complement. Thank you!
Hands down one of the best explanations I've seen for comuter related math. This video is from '09 and it more concise than other current videos. Thank you!
Thanks for this video. I tried read articles online to understand this and it was impossible to wrap this around my head until I saw this video. The practical example helped me understand.
Very clear and concise explanation. I was thrown initially when you added the bits. I watched another video explaining how to add bits and then came back. Can't thank you enough.
this is why people need to realize are in the 21st centuary...books are obsolete for the most part. guides like this one are helping the community move forward and we thank you for supplying it.
I never respond to videos but I really had to do this. I'm a computer engineering student and was behind on twos compliment and looked up these videos. This was really great. I learned what I needed very quickly. I had even read the section in the book before this and was lost. Within the time of this short vido I had it in no time. Very very good!!
Great sir, actually i am taking these stuff in introduction to digital logic design and from the first class, i found out that i will not understand any thing from my instructor since he is just writing formulas and examples with no explanation of "WHY" you have made it so easy to understand why we want to find the "Complement" please keep going on sir i wan to pass this course :D
Such a great explanation -- I had a quite good (but still against that description) diffuse understanding. This video I will NEVER forget. Great teacher. Thank you very very much.
It's all so clear now! I can't believe I paid all that money for a silly textbook that can't even make something THIS SIMPLE comprehensible. Thank you! :)
"2, I like your curve and you're easy to work with." It's not so hard to compliment a 2. They're very nice numbers... Joking aside, I agree that these are great tutorials. Thanks for all your work!
I like how you go over everything and take your time. You assume we know nothing which is good! :) thanks a lot brohan. You remind me of Hank from Breaking Bad for some reason.
Two's complement just means half of the available bits represent negative numbers instead. 8-bit means you can represent -4 to 3 instead of 0 to 8. This also means that a negative binary number is different depending on the bit system. For example, 100 is -4 in 3-bit, but in 8-bit, it's 1000 0000. So to use two's complement, you MUST know how many bits you're working in. -1 is always 1 000 .... because it happens to be handy when performing binary arithmetic.
I've just gotta say, youre really good at explaining this stuff. I'm studying for a Digital Design final and i was really hoping you had more videos haha.
Thank you for posting part 1 and 2. I'd forgotten how to work Twos Complement. I've started restoring a PDP8/e and the op codes are all twos complement.
@TheBinray you add 1 to the number, that is 1 in binary and 1 in decimal also (with possible leading zeroes, but those are only for computers). You don't add digit 1 to LSB nor to all digits, but you add number 1 to the original number. It is that simple.

This was explained very well. Thank you. It's exactly what I needed. You should consider doing more videos.

You explained better in 15 minutes what my teacher spent an hour. Thank You for the video.
These videos were very helpful, I had no idea what two's compliment was prior to viewing these and now I feel like an expert! Thanks!
Hands down one of the best explanations I've seen for comuter related math. This video is from '09 and it more concise than other current videos. Thank you!
My saviour. I was so stressed about this that I was in tears. Thank you so much for this.
Thanks a lot. I was looking to refresh my mind. I learned it about 30 years ago and now it's crystal clear again.
Thanks for this video. I tried read articles online to understand this and it was impossible to wrap this around my head until I saw this video.
The practical example helped me understand.

I like the fact that the videos are not long, but they explain the thought precisely.

Thank you for this. Your explanation was fantastic.
Just simple intutive tutoring (in short time video), explaining most of the pros, cons, uses and application. Thank you.
Great video! First time I have actually made sense of 2s compliment.
Thank you!

Thank you very much for making this video.
This is no doubt one of the best explanation on this subject on YT.
Video's like this make up for teachers who cant expain it properly. thank you alot and now i finaly know how two's complement works.
you're awesome. I'm a returning student so i haven't seen this material in 15 or so years. You were clear concise and did i mention, awesome! thanks
Thanks for this video - excellent explanation coming from someone who clearly has an advanced and thorough understanding of the topic.
Amazing! I have an exam in 3 hours, and 2 complement is a possible sub question. This vid saved me 30 extra min of sleep! Tnx a lot
I never respond to videos but I really had to do this. I'm a computer engineering student and was behind on twos compliment and looked up these videos. This was really great. I learned what I needed very quickly. I had even read the section in the book before this and was lost. Within the time of this short vido I had it in no time. Very very good!!
Wow, this is the best video on explaining signed integers :D Helpful for tomorrow's exam!
That was fantastic... so clear and helpful

please keep going on sir i wan to pass this course :D
I wish I could kiss that genius bald
Really nice and simple explanation without the unnecessary complicated mathematical jargon. Thanks!
Love this video! Great teaching.
Thank you!
Such a great explanation -- I had a quite good (but still against that description) diffuse understanding. This video I will NEVER forget. Great teacher. Thank you very very much.
Give this man a gold medal!!
It's all so clear now!
I can't believe I paid all that money for a silly textbook that can't even make something THIS SIMPLE comprehensible.
Thank you! :)
I have been struggling on twos compliment until watching your video. Thank you! Fantastic teacher :)
Simply the best explanation on the internet...
Please make more! Your videos explain these techniques so simply!
Thanks so much! You explain things in a very simple comprehensive way. BTW, the soundtrack is really cool
Wow , Just wow. This guys made things so simple and explained so effectively as well.
you are great. thank you dave collins
Wasted hours reading about this and finally came across this video. Awesome explanation
Thank you! I have a midterm about this and you explained it a lot better than my professor.
You put my instructor to shame. Nicely done, sir
just spent an hour in lecture for this and didnt understand it at all. watched this and part 1 and i totally got it cold now. thanks!
WHY BIEBER HAVE MORE VIEWS THAN THIS?
THANK YOU PROFESSOR DAVE !!!!!!
old video but very very useful, thank you very much sir!
Thank you so much. You explain it in such an easy way. Both my book and teacher makes it sound harder than it actually is.
Amazing explanation. All concepts are explained in a precise manner. Thank you.
This helped a lot. Two's complement was confusing the heck out of me until now.
Great job, sir! I needed help on SM, 1C and 2C and this video absolutely cleared my concepts. Keep it up! God bless you!
I LOVE YOU THANK YOU!!!!! So much better than what I tried to learn in class.
Thanks for the great explaination!! I especially appreciate how straightforward it was.
Amazing, simple explanation. Thanks.
that was insanely helpful, well-informed, and easy to understand. Thank you!
Better than my professor's explain, lol. THX
My professor told us to watch this since he can explain it better than my professor lol
Perfectly explained. Thank you!
This helped me so much, you're literally teaching me my numeracy and logic class 🙏
Very good presentation with simple to understand concepts. Keep up the good work!
I wish you were a teacher at my school...your explanation was so much better than my professors
this is really good video for those who can't understand by his or her teacher
"2, I like your curve and you're easy to work with."
It's not so hard to compliment a 2. They're very nice numbers...
Joking aside, I agree that these are great tutorials. Thanks for all your work!
AHAHAHAHAHAHA :D
Thank you. This took a lot less time than reading my textbook explanation.
I like how you go over everything and take your time. You assume we know nothing which is good! :) thanks a lot brohan. You remind me of Hank from Breaking Bad for some reason.
yesss. now i understand twos compliment fairly well for my computer science final tonight. thanks.
Very straight forward. Easy to understand. Nice job!
THANK YOU!!!!!!. You made so simple and easy to understand. You're the best!!!!!!
OMG thank you so much! I thought I was going to go crazy trying to figure this out but you made it so easy to understand!
Great video. Good pace, very instructional and easy to follow. Appreciate the video and keep it up!
brilliant thanks. Really clear.
Thanks a lot dude, really helped, your explanation was nice and straight forward
These videos are great. Thank you very much!
wonderful, got the most out of my 18 min!!
The greatest explanation ever... was mindblown
Absolutely, best explanation!!! I wish you were teaching my computer architecture class...
Thanks for the great video! I'm taking an intro computer science course that does a poor job of explaining two's compliment and this helped a lot.
Comprehensive and clear explanation. Thanks.
Why does he have two keyboards though?
That's like having two zeros. Totally unnecessary.
+Alexander ML Jones I have two keyboards too. I'm running a steam machine and my main pc from the same cpu graphics card. So I have two workstations.
Wow, thanks guys. You answered my question well and with class; I might have to get a second keyboard myself. Great ideas
very well explained! thank you sir!
thank you so much for this video. best explanation EVER of two's complement.
Two's complement just means half of the available bits represent negative numbers instead. 8-bit means you can represent -4 to 3 instead of 0 to 8.
This also means that a negative binary number is different depending on the bit system. For example, 100 is -4 in 3-bit, but in 8-bit, it's 1000 0000. So to use two's complement, you MUST know how many bits you're working in.
-1 is always 1 000 .... because it happens to be handy when performing binary arithmetic.
Need more videos! These explanations are terrific!
Thank you! Nice video! Keeping it simple with easy to understand examples
This was really helpful for my assembly language class. Thank you!
great lecture........u r amazing .....thank u for that lecture........looking forward for more...
Wow, i really understood that! My books never gave an answer.
Good Job!!! Please go on making videos!
I've just gotta say, youre really good at explaining this stuff. I'm studying for a Digital Design final and i was really hoping you had more videos haha.
Thank you so much. You made it so simple.
Kind regards...
You're a very great teacher. Way better than the one I am paying for... Shutup and take my money.
Thank you for posting part 1 and 2. I'd forgotten how to work Twos Complement. I've started restoring a PDP8/e and the op codes are all twos complement.
Thank you for making this seem so easy. Seemed so complicated in my reading.
superb lecture
Exactly what I needed, and it really help me understand the three
Thanks a lot. l learnt from these two videos more than l expected.
excellent work .... i wish i had professor like u .... Thanks a lot.
Best explanation I've seen. Thanks.
I think you just saved my grade for tomorrow. Thank you
Wonderful video. Very very helpful and well-made.
Awesome video, I was trying to figure out how the whole carry bit thing worked when Iw as working through a java book. Much appreciated.
Ah... This was awesome; I wish you'd do more of these computer engineering videos.
I wish you made more videos. This was so helpful!

You sir, are an excellent teacher!
Brilliant!! Thank you, you possibly saved my degree
Thank you, that was fantastic, very clearly explained.
