I play a game called Space Engineers. I do a lot of math and number memory in my head when building and deconstructing creations in-game. Most gamers use digital calculators plus a pen and paper. I bought an abacus to learn something new.
hi joe am 40 and hv always had problems with adding even basic numbers by head. is it too late to learn the abacus and do u think it can help adults too like me?
4 beads in Russian счёты - are used to represent division into quarters as well. I remember a time when there was a Russian abacus in every grocery store.
Thanks, I have a legally blind friend who can do crazy math in her head. I found out she learned on a cramer abacus. I am looking for the best way to learn.
This series of videos, using the Cranmer abacus, is a good place to start, because it uses the counting method, which is the easiest way to learn. th-cam.com/video/mmatTQ5hynw/w-d-xo.html The Cranmer abacus has a felt lining that prevents the beads from inadvertently moving on their own.
Joe I have used a Japanese abacus for years. When my children were learning math I taught them using an abacus. I told them when you start thinking of numbers like 88 as 90 -2 or 49 as 50 -1 it will all become easier to you. They now teach their children the same way. I wish american schools would just touch on this and math would loose allot of it's mystery to young kids. When they think of numbers as multables of 5 rather than 10 it all falls together.
When I was in high school and college, in order to break the monotony of using an electric calculator to figure out chemistry stoichiometry problems, I'd use my wooden Chinese abacus and a book of log tables. I still use the abacus in conjunction with Turbo Tax to figure out my taxes.
@@serglian8558 how long did it take you to come up with that though? ;) Because my definition just seemed so tailor made to the term and it came to me as I was building my own first abacus. Being that the first electronic computers were pretty much strictly used for calculating sums, I stand by my mine. I do say that with a smile on my face though, and I send you KUDOS for taking an interest.

It is never too late to start, and the abacus makes learning fun!

Thank you!
💯 Excellent video! Thanks.

Thank you for your detailed and clear explanation and instructions on types of abacuses 👍👍👍

Good for you. Thanks for watching.

That is neat!
What a cool thing to collect!
Nice collection.
Good informative video, thanks for posting.
we were taught using 10 bead per row abacus in Australian schools in the 1970s
This is the most oddly interesting thing ever. I've learned something today.
Good day! May I ask how to count the abacus that 1 line in the upper and 5 lines in the lower? Thank you 😊
See this video: th-cam.com/video/oCbwquVh1PY/w-d-xo.html
Very interesting, thank you.
Thank you for your detailed information! Very interesting!
Abacus - A BAck-up for Computer USers
Yes!
@@Joe_VanCleavewhich poses the question: Which came first, the computer or the abacus.
Could also stand for: A Built device Aimed at Calculations for US

Wonderful video!
A little about my abacuses:
my first one was an all plastic one with lots of different coloured beads (which irregularity makes it hard to concentrate on counting to be honest).
I bought it about a year ago or so, on a whim on "our" version of Ebay - without knowing what it was.
I quickly learned some of the basics and was hooked!
So when I found a more traditional one at a second hand store, I believe it was still brand new in it's packaging, I was super happy.
It's one of the Japanese kinds with 1+4 beads, very smilar to the black ones in your video. Mine came with little instruction leaflets too (one in English and one in Norwegian), that says ©1948, revised in 1969 (by Tomoe Soroban Co., Ltd.).
The instructions says that it's beads are made from bamboo, and I can tell the rods are too.
It's the frame that I'm a bit confused about. It looks like it could be bamboo, with a slight graining effect and maybe some of the "dotting" you see at the ends when bamboo is cut.
However, because of it's shiny black exterior (coating) it looks and feels almost like plastic.
Moreso to throw me off, is that the four black rods on the back really seem to be plastic.
But overall I still get the feeling that the outer frame is made of bamboo. The ends of the soroban have that almost rounded shape you where talking about. It just doesn't look like it was made in a mold!
It doesn't really matter what it's made of though. It's just fun to try figure it out! I will have lots of fun with my abacus either way, that's for certain.

Greetings from Sweden!
I love these little details of their construction, it reminds me that they we designed and made by craftsmen.
Not taught in American school.....kids should learn this In grades 2
