So I’ve bought a 17 rod abacus last May and started practicing addition. I’m focusing on addition for now. And, I could now add up to 7 digit number to another 7 digit number with great accuracy and speed. So 3 days ago I’ve tried doing the Flash Anzan. (I know some of you would say that I have to practice more on the actual abacus before moving forward to this). But I’ve just tried it. And I did it. I could be able to add 2-3 digit number to another 2-3 digit number. I’m practicing 1 and a half hr every night before I go to bed. And I want to make sure that every night I made some adjustments or improvement. So to anyone who can do this, do you guys have any tips? Any suggestion would help. Thanks a lot!
P.s: I could already add, subtract and multiply fast using mental math. But I still tried the abacus because it’ll be helpful in some problems.
