Binary Numbers

Understanding how numbers are represented. Introduction to binary numbers

[@Paysanaswylin]

THAT GUY FROM kHAN ACADEMY IS TOTALLY AWESOME! HE EXPLAINS EVERYTHING 100% BETTER THAN ALL MY PROFESSORS COMBINED.

[@PaulaStreet]

I think what helps is the sound of his voice - the deep tone seems to help the listener to absorb the info and concepts - and there is a total absence of any sort of judgemental tone, which tends to be present in the average classroom. Sal just makes learning seem like a comfortable thing to do.

[@woobiesftw]

FREAKING TWENTY FIVE YEARS OLD AND I FINALLY UNDERSTAND BINARY. THANK YOU! I have to mark this day. I wonder if French speakers have a much easier time accepting different number based number systems.

[@MarthaRoseMoore415]

I got a lot out of that, thanks! Also that's a great voice, confident and relaxed, yet sensitive to the student's needs.

[@paulwhite1793]

+Martha Rose Moore (BLUE) Well, sincerely, I don't think that it's not possible. Of course, if you have what it takes and that is: 1-right broker 2-good strategy 3-patience 4-bravery I personaly, do have the 4. I finnaly found a good broker. www.binaryoptions.net/brokers/binary-com/ Patience is present, but bravery-not really. I like to play smart so I would have the courage to try that strategy that is on that table. If you having problem with how it work email at [e-mail].I will be glad to assist thanks.

[@Crinklelando]

Thank you! My tech teacher could not explain this clearly to save his life... I understand it now, thanks again

[@JetCityBeau]

Sal... You totally ROCK! Thanks for taking the time to pay it forward!

[@vanessarivera1361]

Thanks so much! I'm in an IT class in school and I've felt so in the dark about Binary numbers but you showed me the light! It makes so much sense now! Thanks a bunch!

[@IhollySingit]

this was amazing! if i had to rate it from 1-10, i'd give it a 1010 xD get it

[@queensaharaice7376]

Lol

[@s0ckl0rd]

nice

[@steflondon88]

Oh the cheese in these comments, haha!

[@heydulzura]

Yes you like It 101 times more than the max

[@heydulzura]

JK i get it

[@PwnsterNub]

wow...not only Sal is one of the greatest teacher of all time, but his mouse accuracy is amazing. I couldnt even draw a word neatly with my mouse!

[@kupferknochen]

Thanks for clearing this up for me! I had a okayish understanding of binary but now I'm more confident! It's as easy as 1 10 11 😉

[@neorblx1923]

This comment clarified my understanding of binary.

[@kupferknochen]

:)

[@aaronmac485]

This comment is so great.

[@neorblx1923]

I know, right?

[@amiraboodi2075]

Hello, Sal I love khan academy. Your explanation is always so clear and understandable that I think everyone can get it. You are a remarkable "Artist" in teaching.

[@DozerFitness]

Seriously man....I couldn't thank you anymore for the work that you do. My Prof has been trying to teach this for a week now and I finally understood it after watching your video.

[@Nejidabest]

thanks for the clarity in why the 8 6 4 2 is used, I was always confused but you made it clear

[@jacobcredh20]

Thanks being so thorough! Even if I almost fell asleep at the beginning. I've never understood how binary worked until now... Now I have an infinite amount of other base number systems to play around with

[@whitehairedbadass3475]

Thanks alot. The way I was taught we were just supposed to memorize them up to 9. I'm glad i can actually understand the concept now.

[@mazgaj2]

Fantastic explanation. I personally think that what is also important to grasp at the beginning is that computers had to "adapt" to binary since we're working with a technical limitation of an electric current either flowing (1 'state') or not (0 'state'). Then you start to see that there's really not way to implement e.g. a decimal notation and a computer is only able to "see" 1s and 0s.

[@MEGAsporg12]

funny how i learned this in 10 min and my teacher failed completely in one hour!

[@houdinichild7034]

Well this guy in the video (no idea what his name is) may have been working with math much longer than your teacher.

[@WillmiszGaming]

MEGAsporg12 I'm pretty sure, that your teacher didn't even try to draw it like Khan Academy

[@queensaharaice7376]

+Houdini Child Possibly (and his name is Sal😊) also remember +MEGAsporg12 teacher has to teach a whole class! And not to mention some of the students may be disruptive😒😒.

[@queensaharaice7376]

+WillmiszGaming True

[@GabrielSavageMusic]

don't you mean 1010 minutes ;)

[@NghiaTuanLe]

The way you explain these tough information is very clearly and easy to understand. You make it become easy. Thank you. It was hard for me but after watched your video it become easy already.

[@MenaPaws21]

You sir, have helped me so so so so much over the past 2 weeks during my finals... Thank you so much, I really appreciate it!!!!

[@upasian6497]

took me a while to understand you, but now i see where i got you mistaken, and now i understand the binary numbers a lot more.

[@volo7]

i dont know what i would do if khan academy did not exist seriously thanks for these videos

[@mansisingh2669]

Thanks... who knew that binary numbers come in computer science...... THIS HELPED SO MUCH

[@A1324425]

Comp Sci AP test tomorrow, this is one of the best review I found online.

[@SoberBro]

Thank you! You're awesome at explaining.

[@Miliex_YT]

I didn't know that I could understand binary this easy as how you explained it. Thank you so much!

[@alkalait]

Please let this be the start of a 'Computer Science' playlist!

[@maecagampang8620]

This was by far the best tutorial to learn Binary for me :D

[@DarKnightofCydonia]

It's so simple! I didn't have any need to learn this but thank you!

[@heyno9383]

Helps a lot!! esp the twos place and how the reading of numbers actually start from right instead of left :>

[@hamati0]

Wow I needed this a month ago i couldn't get what the professor was saying Hopefully u continue with the computer science stuff

[@PaulaStreet]

Best explanation of binary I've seen so far!

[@JS-gu7fw]

I've had friends and professors explaining this to me, yet this is where I've only understand it. This is the perfect. Thanks!

[@abz998]

Love what you're doing! Please recruit other volunteers to expand the humanities section. Thanks

[@Jppradhan6890]

u really made it clear. thank you khans academy

[@hannahkidd2121]

Your videos are very organized and helpful!

[@jbravous100]

Thanxz alot.....i got it after watching it 2-3 times back to back. Thanks khanacademy

[@justlookabove]

"Hopefully that doesn't confuse you too much"

[@aldekorea]

wow I understood this concept for the first time even I read the wikipedia article. Thank you very much!

[@zachem66]

wow thank you so much for doing this video, please continue this as a playlist and do a lot more on this subject

[@rumiqdj]

This is the best explenation I've ever seen!

[@artimiss1238]

Thanx so much u explained it better than my programming teacher

[@WillmiszGaming]

Wow man, you did so well, that now everyone that doesn't understand, will have a lot of fun from this! Sub and like for you!

[@paulwhite1793]

I think it's possible, but the key here is consistency and focus + patience. Most people lose their cool when they either win too much, or lose too much. That table is pretty conservative, I kindda like it. It's only at 15% ROI. Really good traders with money management and great observation can make up to 35% ROI per month. And imagine if you have a high enough bankroll? E.g. I give you 15K to start off. How fast do you think you will become a Millionaire? 2 years? Go figure...email at [e-mail] I will glad to help if you still having difficulty on binary operation.

[@thesourcebreaker]

this is the best vid for binary numbers!

[@kelseylikescrazyness]

I wish that someone could have explained binary to me like this when I first learned it.

[@perrymaholland2237]

Wow i finally understand base2. thank you!

[@butterflies5632]

Best explanation ever

[@skeletonscorpion]

That was intense. thanks guy, made this so easy

[@yesimstuntdude]

This guy is really, really mesmerizing.

[@sj7213]

THANK YOU SO FREAKING MUCH! I can always count on Khan Academy to help me. :D

[@PaltryPete]

Great explaination. Thanks!

[@LuisFigueroaCovers]

Absolutely wonderful! Many, many thanks!

[@HuTheMan]

4:11 "Instead of making a tens place I could make a twos place. I know it may be a bit COUNTerTWOitive............

[@Brucelee460m]

This makes soo much sense plz take over for my math teacher!

[@eliot0x103]

:O nice, are you gonna be making videos of Computer Science? I've made a binary exercise before that I still haven't contributed, if you want it now let me know! BTW: An easy way to intepret binary is: [128] [64] [32] [16] [8] [4] [2] [1] 1 1 1 1 1 1 1 1 = 255 Basically just double the [X] value for each extra digit and add it, if it's 1

[@dancemyheartoutrb]

thank you so much! this was very helpful to me

[@ayoopdog]

Amazing. Thank you! I learnt about binary :)

[@medicaltips2202]

thanks man.. this is awasome!, really great,,

[@whitstable11]

Hope this is the beginning of computer science playlist ;)

[@Mr_Yin_Yang]

Really good explanation

[@akmore7454]

This was so helpful thank you!!!

[@SourenaDm]

OMGG,THank youu,now its clear for me !!

[@leedira9546]

finally i understand itttt..tqsm

[@sammann2002]

You helped a lot thanks man

[@xiaoyingjennyyi7861]

Amazing

[@lambeon09]

I actually love you dude (no-homo)!! much better explanation than my lecturer!

[@AB_0070]

Thank you very helpful

[@VIPeR010icoN]

That helped a lot , Thanks !

[@sirk562]

Very helpful , this video made me get it :)

[@farazfa3766]

06:46 Hundreds was ten times two, not ten. Thanks your videos are awesome.

[@zulfitareen1]

nice. it is working. thanks

[@VashDeeStampede]

Super teacher.

[@mikewallace6383]

Salute to a real 1

[@nelggyboy]

Well explained.

[@AhmedSedik]

wow first time to understand this :)

[@paulwhite1793]

I am glad you do understand I think it's possible, but the key here is consistency and focus + patience. Most people lose their cool when they either win too much, or lose too much.

[@onobonono]

Yes!!! My Physics teacher (I know, it's weird that we're learning this in Physics) is terrible at explaining this!

[@chasepf]

Sal, you rock.

[@makentoarts986]

the best explantion

[@luhole]

Awesome, thank you.

[@binaryanimation8137]

thanks for the study help

[@stigenlund]

Hope to see more computer science vids

[@guerillachan20]

thank u man i'm freaking taking digital systems and i got no clue whats going on.

[@irinakoay]

Thank you very much!

[@MazharAbbas-xn1tz]

Which Software You Use For Typing in Your Video????

[@solomonthell7589]

I prefer base 10 number system -_-

[@Theveronspecie]

+Solomon TheCursedOne actually I think base 2 is easier. I don't know if it's me but the way he explained it was so confusing

[@my4tune331]

i like them both

[@MarinPetricevic]

Honestly I'm subbed but don't watch all of these vids. And watching this vid got me thinking "what kind of dumbasses is he explaining this to? it's simple" then I realized I watched a vid about economics and he explained it quite nicely... then I realized that I was that "dumbass". And that's the beauty of this channel. No one know everything. Even thing some one else would consider common sense is unknown to someone else. And that is why he can't teach you programming

[@LearnMathsFree]

Thanks for the video!

[@ozzlikemike]

Must say thank you Sir!

[@kargaroc386]

Lexicographic ordering? The least significant digit goes up for a while, but then it goes down and the digit to the left of it goes up.

[@nsimmons9427]

Thanks! So pretty much if binary denotation doesn't automatically represent a concrete amount of "things" for you, you can do simple multiplication conversion. That way 0000 = 8421 and 1111 = (1*8)+(1*4)+(1*2)+(1*1)=15 :D :D :D D :D

[@SummarizeThiss]

He is a genius.

[@JalebJay]

I love to use binary for the fun of it, people always get lost so it is fun to confuse them. Btw base 8 is way better than base 16 or 2

[@karencita4582]

This video helped me so much! Thank You!

[@navanpotter2646]

Please teach my math teacher this. :) Thank- you!

[@lunx_lovegood]

I was totally confused but thx anyways

[@sterlingh9586]

Would 105 be 1101001? If it is i understand this. Please help!

[@abulmalikali2460]

Lt Lobster your correct but idk how u got it, i checked the answer on an decimal to binary converted can u explain how u did it for a number so large, the calculators answer was (01101001) which i think is the same as '1101001'

[@sterlingh9586]

So you want to know how I did it?

[@abulmalikali2460]

yea

[@RebornLegacy]

Lt Lobster Are ya gonna explain it? wtf.

[@sterlingh9586]

Damian Louden Jeez man. This is how I did it. So first I found out how many spaces I needed which is 7. Then I went through and added 64, 32, 8 and 1. Remember: there can only be one order that you can do this so you need to choose the biggest numbers first, then the small.

[@ShaniAvraham]

i finally get it !!! THANKS!

[@Jumbotron77]

Very interesting, thanks. :)

[@meowdora1615]

is hard to understand........i still dont understand it...

[@VIPeR010icoN]

+meow meow What do you not understand about it?

[@paulwhite1793]

the quick brown fox jumps over 13 lazy dogs...O.o?

[@hellokat68]

it would be way easier if you post accurate subtitle for us, the caption does not match what's said exactly

[@LeslieR94]

how would you do this for a decimal like 2.125? and negatives?

[@cheloadao]

Thank you 😊
