Abacus Lesson 1 // Introduction, Proper Technique, & History of the Abacus // Tutorial



welcome to the first lesson of abacus this is in this lesson all we're going to do is really just kind of get a feel for what the abacus is some of you may have heard a little bit about it and may have I don't know know that it's ancient and and that Chinese people use it or something like that but I wanted to tell you a little bit about the history of an abacus so you know exactly what it is and what it represents and why it's such an important part of history and also why it's still used today the abacus is still a very though although it's an ancient tool it's still still a widely used tool in many parts of the world so the first abacus you could say was a sand pile if you want to think of a bad like that a portable sand pile the first what they would do is they'd have a tray made out of clay or wood and have a thin layer of sand in there and this sand they would spread out and I guess you could say they would use it a little bit like a chalkboard or something like that before they wrote on anything they would just mark with their fingers or with a stick that whatever marks they needed to mark to indicate what they were counting and that was kind of the earliest known abacus because abacus is actually a latin word meaning sand tree and although you know what you see here is what we think of as a modern abacus the word abacus actually means sand tree and the word originates with the Arabic word I don't know how to say it a little bit a BQ which means dust or fine sand so after that as you can imagine maybe technology and improved a little bit and they move beyond sand boxes and started using pebbles and there was some where they use pebbles in the sand and instead of drawing in the sand they would set a pebble in the sand then moving on a little bit beyond that once they got good and working with metal and all that they created an advocates that have little grooves in it that the marble could slide up or down and allow them to count based on the position of the marble and this started to look a little bit similar to what we see today in the abacus so eventually they came up with a bead abacus and ones on the one like you see today that has written you know where these beads are on rods and it was don't lose the beads as easily there they're attached to it they can't fall off you can imagine how that might be a benefit to not lose your counting beads all right let's talk a little bit about the abacus the parts of the advocates and how it works right in the middle here we have what is called the beam or the reckoning bar and when using an abacus a bead only gets counted when it's touching the reckoning bar or the beam so this bead gets counted when it's touching the reckoning bar or the beam and the beads up top also get counted when they're moved down towards the reckoning bar now these these beads up here are called the heavenly beads these beads are worth five down below in the earthly beads the well down below these are called the earthly beads and earthly beads are worth one each so up here this one's worth five these are each worth one you see you'll see something else here there's a little dot there's always going to be a little dot every three rows so there's not one here but there would be anyways every three rolls there's going to be a dot and that that marks so we understand that shows how the numbers are broken down or what they represent you'll also notice that in this the sorbonne and the not everyone not all of them will have this but I like the ones that do that chain also change colors every three beads so you can see every three rows of beads so that you can see this division of three I mean think about how we write numbers and we always divide them into threes if you write the number 100 it's just going to be one zero zero if you write the number 1,000 we generally put a comma after the one so it goes one comma zero zero if we write the number 13322 1 3 comma zero well three hundred three two zero if we write the number for example twenty three million four hundred and fifty six seven four hundred fifty six thousand seven hundred and eighty nine let's talk about how we're going to count with the abacus a bead is only counted when it's touching or up against this reckoning bar when it's moved to the middle in other words the top beads are only counted when they're moved down and the bottom beads are only counted when they're moved up so let me see that again let me say that again a bead is only counted when it's touching or moved up against this reckoning bar or the beam so a bead is a top bead a heavenly bead is only counted when it's moved down and the bottom the earthly beads are only counted when they're slid up now let me let me point out one other feature that this abacus has not all of them will have it but this one comes with a handy little button right here I like I like that because – clear – clear your abacus all you do is tip it down and hit that beam that clears it also does it it doesn't matter what your beads are doing that clears it now if your abacus doesn't have that if you had one at home and like if you're one of those awesome people in the world and just happen to have an advocacy around I let's if you don't have that the way you clear your abacus from some large crazy number like this is tip it down like that and then with your finger clear it like that that's how you clear an advocate of these beam things here let me do that again so we have some crazy number here like that tip it down run your finger off and you always do it left to right that's how you clear it in general if you want to keep with good abacus technique and it's going to move faster if you if you learn these things from the beginning you'll be able to manipulate the abacus faster is you only use your two fingers your thumb finger and your index finger and the thumb finger it's only job is to move beads up that's its only job the index finger moves things down and his job the index finger here he can he's the only one that can touch the heavenly beads thumb can touch the earthly beads and he can only move them up but the earth the index finger can touch both he can move that one down and up like that or you can move those down like that that's how it works so once again you're only using these two fingers the thumb moves them up the index finger can move them down he can move the heavenly bead up or down but the thumb can only move them up the index finger moves them down or if you can clear them all like that once again

  2. Thanks for the video
    Спасибо, за видео! Начал изучать!

  3. Hello the HEV project . I am Japanese! I also learned SOROBAN as a student (^ ^) I think that is a very good study method!

  4. You are a great teacher. I wish I had learned the abacus in first grade. I love it. Thank you. -Theodore Alexander Vegh

  5. You need a script dude. You repeated yourself several times and even left off a 0 in one of your examples.

    This was truely painful to watch.

  6. i have an Abacus I purchased in the early 60's with 23 rows of beads and 3 dots in the middle. I'm curious about the 3 dots.

  7. I hate when someone is thinking in his head that is doing a great great job while sucking at the job.
    Your way of explaining is very terrible and boring. You can give lessons animals but not humans. Saying 3 or 4 times same thing is very annoying. I would never subscribe in my life on your channel.

  8. Too much time is wasted on simple things. Explaining moving up and down doesn't need much of explanation.Just a critique for improvement.

  9. OMG!!!!! PLEASE, FOR THE LOVE OF GOD!!!!, Get ON WITH IT! Who cares what finger you use to reset the beads, use your f****ing toes if you want. As long as they are back to the default position who CARES! No wonder you have 33 videos about learning to use the Abacus, not because it's complicated, because you're a moron. I'll find another video to learn about the Abacus, you're ruining the fun of learning about something new. Sheesh!

  10. As far I know I was invited 5000 years ago and some historians believed that the abacus was invented by ancient Chinese while many more believes it was actually invented from Babylonians or the Egyptians!
