Who knows how to use the Abacus?...
I learned it back in 1st or 2nd grade I think. after that I chose calculator..hehe.. I find it hard, but i find it as a good tool to use in order to learn the basic math and have a better fast calculation technique inside your brain I guess...lol..and its good to impress people..haha
Check out this Video of kids with Amazing super fast calculation using the Abacus...this is insane...I don't know who can compete with this people.
I think Im going to have a nosebleed if I learn to adapt the way they calculate things. Everytime I watch this, the kids look like they're going to the matrix world..Im not sure how to fully explain that...lol
