- This video shows you basic multiplication with the Soroban and compares it with long-hand on paper. NOTE: I know where I made the mistake multiplying by hand, see if you can spot it and let me know in the comments!
I was pleasantly surprised to see Trachtenberg Method of multiplication being used in a soroban! Thanks for the video!

My coworker & I were playing with our abacus which are in our phones, we were multiplying numbers together & both of us got Confused af. 😅. We're still trying to figure it out.
Try some Soroban-based games, they teach you and increase level and complexity as you learn, making it fun!
Thank you soooo much
Glad to help!
my brain hurts
Once you practice it becomes automatic, even faster than a calculator. There are games you can use on your phone to play and learn and then you don't even think anymore, you just do it!
@@devhackmod can you share apps to improve soroban learning
@@fatihakhan4381 I would search the app store for "soroban"... Lots of fun apps to practice and games available!
I concern I might lost my paper and pen way of working it out as well.
Best
Soroban's are awesome, too bad more people don't know about them here in the Western Hemisphere.

Can there be a faster way?
Once you learn how to use a physical Soroban to calculations, experts begin to imagine a virtual Soroban in their heads and can do calculations faster than a calculator just in their heads. So yes the Soroban can be faster than calculators in certain situations and by experts. Just watch the Soroban competitions, even young students are amazingly fast!
Yes, for 3 digit by 3 digit, there is a faster way. Look up vedic multiplication. Soroban can help in it as a nice accumulator register.
Sorry Sir,why is your soroban even and odd?
What do you mean even and odd? The columns are grouped into 3-digit to represent thousands, millions, etc. if that's what you mean.
This is BS, not only do you have to learn the math, but the abacus also. Its much easier on paper, the method never changes. Learning the abacus is more work, furthermore there are more calculations within it you have to do. Why are you subtracting 6 in a multiplication. Then theres making sure you don't misplace a bead. So when you add it all up theres a possibility in adding up the wrong answer, cos a bead might slip. Theres a reason the calculator was invented.
I'm not gonna pull an abacus out my pocket if I need to do some number crunching 😂
Leave the abacus in the dark ages where it belongs.
It helps learn the mental math better, and when you’re in a test with no calculators, when you have an abacus in your head you have a calculator on you at all times.
Abacus for kids is a great tool.
The abacus is the ancient computer. And it's not bs. It's how you're able to type on the internet rn.
