Crash Course on Abacus: What is it and How to use it?

Published on October 16, 2025 | By Jainam Online Classes

Long before the age of smartphones and the internet, we had tools and objects that were used in place of those. Maybe not all youngsters will remember what a physical letter looks like or how pigeons were used as messengers. But that doesn’t mean they didn’t have their charm. As ancient as they are, their use defined the future. In that same way, before calculators, we had a thing called an Abacus. So in this article, we will learn a few historical significances of this tool, and how is an abacus used.

Counting before Numbers

Now math consists massively of numbers and elements like letters. But did you know that these numbers were invented far in the future, and counting existed way in the past? 20,000 years ago, to be exact, where in central Africa, Ishango bones were discovered which had notches for counting. But by 3000BC, merchants from around the world had already been familiarised with a manner of counting with beads sliding across a thin line. It was called calculi, which roughly translates to Calculate. That is our old calculator with beads, which later became renowned as an Abacus.

Did anyone invent the Abacus?

As unique and groundbreaking as it may be, there is no historical proof that it was invented in a single place or by a single person. As it stands, suddenly merchants from all over the world simultaneously invented this tool, and it was known that they had only done so after their trade reached to the West, where most things are recorded. That’s why we see various kinds of abacuses out there. Some have seven beads, some have five, and some even have 10 or beyond. That symbolizes the diversity of the abacus, and how is an abacus used.

But wait, wasn’t there a turning point somewhere in history? Well, yes, and it again goes back to our classical Roman Empire. They had a thing called Hand Abaci, which was inspired by the Salamis Tablet from Greece. Technically, both are the same thing; it’s just that the hand abaci is more portable. And since the Roman Empire was a trade hub at the time, the idea quickly circulated. That may have been the biggest turning point, but not the only one.

The Mental Abacus

The old calculator with beads soon became a thing of the past, as people learned the way to make a mental image of an abacus and use it to calculate. This was not just quick, but also efficient since now you no longer needed to use your hands to hold and move the beads physically. Heck, people even stopped looking at the person speaking; the ear is all they needed to hear the number, and the rest was handled by the brain. Credit for this turning point goes to Japan, which truly glorified mental math to its finest. India also had some big hand in it, and so did Vietnam. These trade-heavy places were the first to take full advantage of the old calculator with beads, until the calculators arrived.

Did Calculators Kill the Abacus?

In a sense, it looks like calculators killed the abacus and depopularized it. But in reality, it didn’t. Let’s stop for a bit and understand for whom the calculators were made. It was made for the commercial sectors like banks and corporations. Because adding a massive list of numbers and getting instant results was important. Like, come on, no one would like to wait for hours at a bank counter, right? Slowly this trend spreaded across all sectors like education and even home accounting.

Fundamentally, calculators just gave an easier way of calculating that didn’t require the time and efforts needed, like how is an abacus used. You can’t do math like crazy from day 1 with that old calculator with beads, but with the modern one, you can.

Overall, the abacus is very much alive, and a lot of countries like Japan have mandatory curricula in schools for the soroban or suanpan methods. We all know that an abacus is more than a tool; it is an experience that comes with important skills like critical thinking, concentration, memory, etc, which digital calculators just can’t provide.

How Abacus Works?

Well, by now it should be clear why the old calculator with beads has such significance. With that out of the picture, now let’s see how abacus works in the most simplest form. Remember that if you want to learn this in more detail, click on the read more link above. Anyways, here’s how it works:

  1. Get the simplest abacus possible. Let’s assume you got the 13-column or rod one.
  2. Each rod will have five beads, that’s your number.
  3. Each rod, on the other hand, represents powers of one, ten, hundred, and so on from the far right.
  4. Now let’s do some basic calculations like four. Slide the beads from the first rod from the right to the top. That’s number four.
  5. Let’s do seven this time, slide all five beads from the first rod up, that’s number five.
  6. Each bead from the second rod represents the number five. So now you can trade your five beads from the first rod for one bead from the second rod.
  7. So slide one rod from the second rod up, and slide all five beads from the first row down. Now we have five, but in different ways.
  8. Now we need to count two more, so slide two beads from the first column up. That’s number seven.

Congrats, you just learned how to do basic math with your very own old calculator with beads. Was it difficult? Well, not for now. But as you learn other forms of calculations like addition, multiplication, division, and so on, it will become a bit more challenging. Still, the reward is worth the struggle, and learning how is an abacus used.

Positive Effects of the Abacus on the Human Brain

At this point, it is painfully clear that Abacus does more good than harm. It stimulates the brain so much that it is forced to evolve and turn its host into a superhuman being who can do it all, without breaking a sweat. But that’s only one of the few effects in its arsenal, and the rest looks like this:

  1. Brain Development
    1. By stimulating the left and right hemispheres of the brain simultaneously, it awakens logic and creativity at its peak.
    2. Neural connections weakens over time if the brain isn’t used properly. An abacus counters that with continuous calculation and immense visualization day after day.
  2. Concentration
    1. Humans have an attention span of just 8 seconds, which is even less than a goldfish. But the abacus also slowly improved that with intense focus on bead movements, numbers, and training of the brain.
    2. It also helps adults and children live in the moment and avoid distractions, even in the most awkward setup possible.
  3. Brain Power
    1. Efficiency is the name of the game, and as always, the abacus takes it to the next level with cognitive processing speed and enabling faster problem-solving.
    2. By listening, visualizing, and calculating simultaneously, the abacus trains the mind for doing multitasking by default. This goes a long way and spills over into every other work imaginable.
  4. Confidence
    1. Being bad at math is one of the biggest weaknesses a child or an adult can have. No one likes being reliant on a calculator all day. But an abacus also fixes that by turning you into a calculator and giving a massive boost in confidence all year long.
    2. Mastery over a large number allows you to do big calculations on the fly, providing a much-needed dose of self-esteem.
  5. Imagination Power
    1. Mental abacus isn’t just for doing calculations; it helps improve visualization of all things, from building architecture to maps, all in your brain. You will be surprised how good you have become in manual navigation just by training with an abacus for a month.
    2. Innovation is the backbone of a successful business, and the abacus again takes it to the next level. Especially for artists who need to imagine what they will draw months before it’s finished.
  6. Memory Power
    1. This is all about retraining and recalling information from our brain, or we can say the hippocampus. The effects are almost instant, and people quickly realize that now they can remember what they ate a week back without any issue.
    2. Long-term retention also improves and allows you to pinpoint a memory and then recall it back. It may sound easy, but not everyone can achieve it. The abacus makes it possible.
  7. Mental Abacus Skill
    1. Simple math is child’s play. But what about complex maths? Well, an abacus trains you to do all that purely in the mind without any tool.
    2. And when you are the master of a mental abacus, your photographic memory skyrockets along with visual thinking, converting insignificant numbers into mental images.

The abacus has much more to offer than these seven bullet points. If you want to learn more, then buy your abacus now and find out. After all, treasure hunting is the real fun around this tool, and the good part is only getting started.

Conclusion

Learning how abacus works is a moderately challenging tool that comes with a lot of additional benefits that no other tool can ever hope to provide. It has a rich past that also gives it historical significance, which makes it even more attractive. Overall, a tool is still just a tool, and if you don’t need it, there is no point learning it.
