Hi
I will be conducting abacus(soroban) classes for adults online. If anyone is interested please send an email to "enrich [dot] brains
The whole course is organized into 6 levels. For now, Level 1 course will cover addition and subtraction with visualization. You can learn multistep addition and subtraction involving all possible combinations. The course durations is 6 hours split into 1 hour class a week. A one-on-one session will be conducted. The course fee is USD199 (I bet you can't find a cheaper course than this).
If anyone is interested to have a demo session, please mail me and I can work with you for a suitable timing.
