- Learn how to use an abacus to add, subtract, multiply, and divide. In this video, Eddy takes a small detour from helping you build a business to learning how to use a 2,000 year old calculator. Why? Because it's a cool icebreaker at a party if you have absolutely no redeemable talents.

I’m about take a placement test and they said no calculators, I’m gonna bring a mf abacus
Daniel Paseur lmao
🤣😂
Useless? Not at all. In fact, this is very useful for young kids in school. They'll have an easier time calculating this way, but unlike with a calculator, they still have to use their brain. Where I come from, children are becoming worse at math because they're allowed to use calcutors at earlier stages of education by the years. Fewer adults use their brain for simple 1-on-2 or 2-on-2 digit multiplications, including those in politics and organizing positions, and they blame children to be that bad nowadays. Shame on them. But this will keep the brain working. You won't have to do much with your brain this way, but the logics part is still there. Unfortunately, this method won't work on, for example, 6-on-6 digit multiplications, and you would need 2 of them.
@@williamwilting then again, children Will most likely not need to solve 6 on 6 digit problems. But its absolute ly right what you are saying.
that would be fine if the abacus wasn't a calculator
It's not useless, those who become very skilled at the abacus can do difficult math in their mind, it becomes like a physical skill that you can perform mentally like riding a bike.
he jacked me up when he said he was going to do a difficult division problem with 125 / 5.... lol
Yea I thought he was gonna do 125 ÷ 4
LOL omg you're killin me...@@seanytcars9510
@@seanytcars9510 , you just made my week
Well it pretty much is useless unless you use a modern abacus like the Japanese Soroban and do it right:

There's always an abacus in children's school rooms but noone knows how to use them. You blew me away!!
ngl i thought it was just a toy when i was younger
no one
or
no-one
Exactly I feel stupid not knowing what it was for this makes perfect sense weird lol
I totally AGREE! I will teach my kids to use this next school year❤😂
Here to learn how so use my three year old’s abacus toy
The benefit of the abacus in today's age is if you get really good at using it, you can visualize it and get accurate calculations for just about anything fairly quickly. I know a girl whose parents forced her to use an abacus on homework growing up and she's in her 20s now but can spit out an accurate answer for anything you throw at her because she uses a combination of mental math and mentally visualizing an abacus. She's crazy fast too.
That is GREAT TO KNOW❤
yep; it allows u to visualize math rather than just memorize and it gets u familiar with binary math. Both are very good brain development exercises.
It is not completely useless. It teaches you to think, keeps one’s mind active.
There’s other things to think about
@@nick_0no no math is very important in so many areas in life. I wish I learned on it. Who wants to always pull out a calculator when you could possibly do it quickly in your head. I want to try this for my kids so they don’t struggle like I had to all my life
@@nick_0it's mental maths it's useless for people who learnt "meth"
I am completely blind, and used this tool all through college!
GalaxY Clark I wouldn’t jump to conclusions; there are many audio programs out there, as well as Braille keyboards
@@simonkawasaki4229 that was inconsiderate of me, thanks for informing
That's awesome! Congrats on persevering.
Ye right if u wear blind how could u write this coment? Jus saying
John Vickers iiiii
why am i learning abacus at 2am
Which country
Which country.
I’m 39 and I had no idea how to use this. Thank you for informing me, I will now file it in my brain in the “useless info I’ll never use” folder
welp, im 25 and i feel the same here.
I wouldn't call it useless; it's a pretty good method to learn arithmetic for visual learners.
Really good video btw :)
I lose track when I try to do math in my head, and I have a hard time memorizing the processes for doing various calculations with pencil and paper, so the abacus is the perfect tool for doing calculations for someone who needs a constant visual.
Agreed! It's a GREAT tool for visual learners.
I think that he was more referring to the fact that with calculators and computers everywhere, it is a skill that is not really necessary to have any more, rather than it being useless.
LainK1978 I'm pretty sure that's what he meant as well, but saying it's "useless" does imply it having no uses, whether he meant it intentionally or not.
There are no such things as “visual learners”. I could point you to a hundred scientific articles on the subject. That’s a myth that’s based on flawed understandings of old research. In reality, we all could benefit from using other sense than the ones we over rely on by default. Think of it this way: most people in the west are not used to using their visual and tactile sense (and aural, if you include the clicking of the abacus) when it comes to numbers. So naturally if they begin to use it, the brain paints a fuller picture. This might lead someone to think it says something their “learning style” but it doesn’t. It’s just that your brain has more information.
Did I see you push 2 beads over when multiplying 21 x 7 but still come up with correct answer
john McNamee i saw it
I think I know what happen, he didn't push the first bead down on top for the initial set of 21. Luckily, without knowing, he push 2 beads down at once and that corrected the mistake.
yes, the bottom rows should have started with zero beads at 4:09 . double move was at 4:26 , probably on purpose to correct the error
john McNamee ya i mean this confused me man!
There is a video cut at 4:26 to correct that.
Great. I remember learning with them as a kid but forgot how it works lol. Now I plan to homeschool and think I definitely will be incorporating an abacus
RightStart Math is what I used for my kids (homeschooling), and it's based on the abacus. I'm amazed at how much you can do on that thing -- we have so much fun with it!
Happy homeschooling. 😊
At what age u started ur children to use abacus? My Lo is 3 years old and i planned to homeschool him.
@@aimankhalid5222 as soon as your child is ready! I've heard some kids can start as young as 3. Others will be 4, 5, or 6.
I knew that you could use them for addition and subtraction but I had no idea you could use it for multiplication, division and roots. Genius.
"We are gonna learn a useless skill"
Later
"This is fancy"
XD
Fancy≠Useful Fancy=Unique or cool
XD
It's not useless. When i saw a cute one at Ikea i got it to teach my kids how to add and subtract. I didn't know you used every row as a value holder. I wasn't taught how to use one. So, now I'll teach my kids the correct way. 😄
You dismiss how valuable learning the abacus is. In the West we learn to memorise our times tables for future use in mental arithmetic (which is much faster than a calculator: you can probably give me the answer to 8x5 long before anyone could even type the 8).
When you master the abacus you can do very complex sums mentally by imagining and ‘feeling’ the abacus in your mind - you may often see people playing with their fingers as if they have a physical abacus in front of them.
Now of course we all have calculators at our fingertips these days but if you know the abacus you could answer 659x 326 before someone has even grabbed their phone and opened the calculator app! Then we can also do powers and roots etc mentally too!
So it’s not a silly redundant device- it’s an invaluable skill that will inherently make your mind faster and sharper and ultimately make you a more intelligent person!
That's why all my Chinese elderly look like they are swiping the table when they are trying to figure out the bill.
Dude, you are so right here. The guy in the video starts off by actually saying "...today we are learning a completely useless skill."
I mean, how ignorantly dismissive can you get?
yeah, i feel like i would do better at math if i had learned through these means, but because my family left asia to live in the west i just go counting things on my fingers, and im an adult now. I feel like I should try to learn these details to get faster by calculating higher sets of numbers in one go. just to get smarter.
@@Bodragon First off my good sir, no need to bring negativity in here. He was trying to make the video fun and intresting and unless you taught your kids how to use an Abacus from the begining even your childern couldn't give a damn about it. What Eoin is trying to say is, not that Eddy is a jerk or trying to mislead or spread false information but the fact that abacus can help you in your early years and then you can toss it in trash. Just like math lovers do with there calculators because why waste time with a machine when you can do it in your head and be correct 100% of times.
Eoin Kelly I learned how to add playing with an abacus at my Montessori school, now I want my child to learn it the same way. Completely agree with you!!
I'm only here because my 3 year old wanted to spend her birthday money on one of these and after she fell asleep I wanted to learn how to use it lol. Thanks for the video
you explained it well, except for the multiplying with 2 digits I noticed you slid 2 of the top ones over instead of 1 at a time. You forgot to slide one in the beginning to include the 21 that was already at the bottom.
I read a lot of medieval themed books and everytime a character uses an abacus I always wondered what the process was so thanks for the tutorial
You're welcome!
Please name some books where the abacus came up!! 🙏🏼🙏🏼
Still using my 4th grade (memorized by flash cards and rote) multiplication tables, and 65 years later this has never failed. A return to this teaching method would benefit the public school system.
I used to think this is the most complicated thing in the world when I was a kid :) Now after 15 years to see how simple they are
this is one of those things that were always at the back of my mind to one day learn, but i never really remembered of doing so. pretty fun and more like a curiosity than anything useful, but still... worth the time.
I can use this when the teachers say no calculators allowed. One of the most useful tutorials in my life. You should watch too
imagine hearing the teacher say that caculators arent allowed so you just pull a giant abacus out of your desk and start doing math with that
.....except that an abacus is, technically, a calculator?
I found several very good and advanced reasons an abacus is not only useful but highly practical for everyday life, over a digital calculator:
1: Digital calculators can screw up long addition chains if you push one wrong button, or the buttons themselves do not always respond when pushed. They also rely on memory and a battery or a power source of some kind and sometimes shut off on their own. An abacus is more reliable than a calculator since it does not come with the added problems and risks of a digital device.
2: I have autism and ADHD, I have trouble with short-term memory and executive function. As a visual and hands-on learner, it's easier to count with some sort of clear visual to work with, like, a multicolored abacus. If I forget where I last counted, I can look at the abacus and see where I'm at. It also engages muscle memory from repetition. As the guy in the video demonstrates, once you get into an established flow, counting starts to be done unconsciously, which allows for fast and efficient processing of numbers.
3: It has career functions. I do inventory logging and simple accounting as a merchant. I have to keep track of hundreds of items and make sure I don't get the numbers muddled. Since most people can't always rely on memory, it's easy to make errors since you're not entirely sure of the steps you've taken. An abacus doesn't require a memory, it's a memory card of sorts for the math you "entered" into it by moving the beads. If you understand where you put the beads, you know what you just entered. Again, very useful for someone with short-term memory issues like me.
4: In a world that seems to be dominated by tech and as someone who has run afoul of the flaws in online and digital technology, it's nice to have the old devices and old knowledge. At least I know I will not be rendered helpless if the tech industry implodes due to corruption of interest and monopolization.
5: I'm a medieval enthusiast and a fantasy writer. I love this stuff. It gives me access to two ways of life and a creative way to explore different solutions to problems. It also allows me to create detailed and interesting writing by mastering the nuts and bolts of life from a bygone era.
🤔You might want to look into Slide Rules and Napier Bones. They are really cool mathematical instruments of years gone by. 😎
Why is this not taught in schools? I’ll teach my son how to use one
Thanks for the basic tutorial, I knew how to add using an abacus as that is straightforward even though I've never actually used one however, I wasn't sure how you do other mathematics on them. Cheers from Australia.
Great video Eddy.
When I was a middle-schooler in Egypt I remember abacuses were used as a primary form of solving problems, with calculators being used only to verify your answers afterward.
The equipment is obviously outdated but I'd argue an abacus is still a powerful tool for building one's mental arithmetic skills.
mueez adam they say that the mathematicians from thousands of years ago were much better than today's computers.
I wouldn't say better than today's computers; but better than today's computer users by far.
This is fantastic! Thank you! I bought this EXACT abacus yesterday from a charity shop - £2!! ...For my nephew who loves numbers. I came to youtube to learn how to use it, so I can reach him, and your video came up. I clicked because it was the same abacus as mine - I thought "what are the chances" 😄 I stuck around because the explanation was great! I'll need to watch again to grasp it. But it was great. Thank you!!
This is a great video - it's the first one I've seen explaining multiplication and division on the abacus that I could really follow. I have always been fascinated by the abacus - I just think they are so cool. I love learning how to use them.
Thank you. This is definitively the best 7 minutes i wasted today! No Sarcasm, I really loved it!
Being locked down & trying improve the kids math whilst Homeschooling. Brilliant explanation & very helpful.
Old concept will always be relevant regardless of advancing technology. Love this video and learn the abacus 🧮 techniques
Brilliant. You made it so easy to understand. Got the idea in a few watches. Now I’m going to practice until I’m fast and accurate. That’s going to take longer. Thank you so much.
I have finals. I really need to go back to studying.
LOL relatable.
funny.
Did ya graduate?
@@Science-ev1he yeap
@@valentinakaramazova1007 after 5 years you came back. Im proud of you, bro
Loved your explanation and so did the kids ;-) Presentations need to be a bit entertaining to get the kids interested. They liked your zombie scenario.
Thanks Erik!
Erik Engheim AWESOME
Five little babies
Erik Engheim i
what are you? a jinxy?
This rudimentary system came into use about 2000 years ago and formed the basis for digital computing. How long did it take you to master, Ed? Thank you for the video.
Vy
I thought it was just for counting and never thought i can do divisions with it!
The ONLY thing wrong with your video is that you call it useless. You explained it so clearly and I wanted to find a video to show to my granddaughter, who is just about to start kindergarten. I don't want her to ever think a learning tool is useless. I would love to see you edit that out. Fun is fun, no matter if it can be done a faster, easier way. You even say it is fun, which makes it useful. (raspberries)
It is since we got calculators
this is 3 years late but you could have skipped to the part after he said it was useless, then called your granddaughter and pressed play.
P.S. it is beyond the shadow of a doubt useless, even in 2017 when you made this comment.
Thank god someone takes serious the preparation for the zombie 🧟♀️ apocalypse
I’m microbiologist we barely use math in our work, I also have finals but instead of studying I’m here learning how to use an abacus !!
This is by far the best video on all things abacus. Thank you!
7:11 It's not useless! It's completely functional. My husband got it for our kids but I ended up liking it. I looked it up. The sumerians used it!
You might enjoy this video. The japanese version of the abacus is the soroban. There are heaps of tutorials on it.
ruclips.net/video/s6OmqXCsYt8/видео.html
for me has always been a mistery how it worked... i has one but never unterstood it... so now im happy starting 2017 one less problem and one more lesson taken
But that's not even a proper abacus?!?
Amen to growth
Very clear and helpful video. Thanks for posting!
Your video is so helpful and much easier to watch than the other ones. Straight to the point and engaging. I need to know this as this works for students with Visual Impairments.
That was actually awesome! I think that could help children learn to count easy!
thank you for a helpful and fun video
Thank you so much. I needed the info to reteach my grandchildren how to look at numbers and math. You are a God send
Why when he did 21x7, he mistakenly moved 2 beads instead of 1 in 2nd row from the top & still got the right answer ?
There was a quick takeaway, i think they edited it
that was AMAZING! dont underplay the skills...the brain muscles were throbbing and pumping in excitement! :)
This is not silly, it's awesome. Knowledge is the only way to alive.
Not at all useless, it gives you a better understanding of what numbers are and how they work. Excellent explanation!
This is very cool and well explained! Love it!❤
I bought one for my son for x-mas, thought I should know how to use it in case he asks though at 8 months old that may be a while. Great video!
kaput450 you need to get better at procrastinating
i guess its just grouping haha. i had know idea. but it's the world's first computing system. or "computer" so it's pretty neat to know how it works. Thank you!
Learned to use an Abacus when I was little, but totally forgot “How”, so popped onto YT to relearn (Math is my Nemesis), so glad I found Your video! You make it seem so easy, and I can’t wait to do some calculations of my own...Thanks for Sharing & Teaching..
Which abacus do you use and did you try to learn a different one?
Hi just wanted to say Thank you so much for this video....useless or not, knowledge of new things is a good thing. At 49 years old, I never knew how to use an Abacus, for that I thank you!!
Me for no reason: "Why is he holding it like a Harp"
so I'm teaching my kids to use it and you have been the most helpful out of all these other dumb videos so it may have been useless for you but super helpful the generations coming up!
Gwen Floyd word
I had abacus as a kid but never new how to use it properly, we just counted the beads 😂 this is awesome, I will buy one for my daughter ❤
Awesome tutorial! Thank you for making it easy to understand
There's a reason you can still buy something dating to the 2nd Century BC - How could something which helps us do math ever be 'useless'??
It's a toy for kindergarten kids who like to push beads around.
"..6, 7 , 8" *whispers "who do we appreciate" 🤣 2:55
Thanks so much for posting. Totally worth watching
This is awesome! Loved the explanation, and learned something too... Now my son's abacus is a fun learning tool, not just a thing with pretty colours that makes a lot of noise when he shakes it....
Who else watchin this in the zombie apocalypse
🙋
Yeah in the negative year on the x axis -6000BC, the brother dimension
this is not useless !! zombie apo IS coming !! good job on the vids
Ha ha. Get the guns!
Thanks for the notification
time to watch all the zombie movies and TV shows to prepare for it
I am mathematically challenged, but this was interesting. I've been thinking of buying an abacus for my granddaughter, who's about to turn 1. I figure it will be fun to play super simple math games with her and we can increase the complexity when she's older.
Very Helpful In Getting Started With Abacus, Loved It!
Excellent for visual learners! 💛
if your calculator sucked up use your trusty old 2000 year old calculator
Great Explanation.... i loved it and I am going to teach my kid to use abacus.. it seems kids still struggle with understanding place holder using conventional system..
It’s 3 AM and I’m watching an abacus tutorial
Same!!!
It is very helpful thanks for u great explanation 😊
GREAT VIDEO
MORE CLEARER THAN OTHER ONES.
T.Y.
That opening statement was hilarious! 😂
huh, well I learned something new today. Thank you, I've always wondered how to use one of those and now I do.
but what if there's decimal numbers involved though? how can you do that? I asume that this only works with whole numbers.
It does work with decimals. I use it to do accounting (money = 2 decimal numbers)
You'd just allocate more beads for the Tenths, Hundredths, Thousdandths, etc.
I really want to find a credible and intellectual video on how an abacus really works.
"Hello everyone today we are going to learn a completely useless skill"
*Clicks back button*
funny thing is he actually teaches you how to use it.
@@DonutKop And does a really great job walking through all the steps
I also didn't like the negative comments at the beginning, it's not about your viewpoint ... its about your audiences viewpoint..
Yes I could be useless to some people because of technological advancement but it's still good to gain knowlegde about it.
hahaha I almost did the same thing....it turns out that he was being sarcastic
It was fun to learn. Thanks!
I love how you explain it. Good job
I knew that since grade 1 the teacher demonstrated it but never let us do it
21x7 takes less than 1 second to do in my head and this took 53 seconds!! SMH 🤦♀️
Can’t imagine the (Convoluted) Common Core.. 5 minutes? 😂
Ok I was given and taught the abacus even before I started kindergarten in Asia. But the best method was to work it in my head faster or the borrow method, because we’re family business merchants and speed calculations is key or you lose..
Ok for those of you who’s lost here’s what you do in your mind:
10x7 =70
2 x 70=140
(because 2x7=14 & 14X10=140)
140+7=147.
Way I do tips:
$25.97
Tipping 10%
Move dot back $2.597 round up $2.60 because we don’t have anything below pennies. If you’re generous 20% you double it.. $5.20)
This was really useful. Or at least fun. And now I know a little bit what to do with the abacus in my kids room. The next step is to teach them. Wish me luck!
Awesome!
Im trying to teach my 6 year old how to use it, I’m going to show him this video!
Actually I like it better then a calculator. I’m dyslexic with numbers but my brain seemed less resistant to it.
Great video! but at 4:26 you moved two beads at once on the top but it did not mess up the multiplication of 21 by 7 because you should have started with no beads on the bottom instead of one on tens and two on ones.
Shahidullah Kaiser Ya and I'm wondering why he got a correct answer
Totally not useless my kid got an abacus for Christmas and this was really useful to learn how to use it. I think it's going to be great for when he's learning math in school.
love your sense of humor.
Thanks, just got one for the grandkids. Now I won't look like an idiot when I show them how to use it. 🤣
:D
You’re a beast.

Why didn't i learn this in school? would've helped a lot during the early years
THANK YOU!! I love this!
Thanks for using the word ‘crap’ while I was showing my child how to use an abacus.
Crap ain't a bad word wdym
Shut the fuck up, your kids will hear it eventually.

Ugh my standard brain thinks this is complicated
Mines too. I'm totally confused
Ditto
I think because he was talking too fast...
😂😂😂
For me its fine bet when it comes to division and multiplication its complicated
I love it!!!!! I’m going to learn this with my boys!!!!
These are awesome to use! Great for kiddos. ☺️
It was annoying you kept calling it useless. I got it after the first time.
edin shealtiel racist
It's useless
Another approach to teaching your kids math!!! This ain't a USELESS skill bro!
Extremely fabulous explanation.
