What is the Soroban?
The Soroban (算盤) is the Japanese abacus used since the 16th century. Expert users calculate faster than electronic calculators — not by memorizing tricks, but by visualizing bead movements in their mind (called Anzan). This course teaches the exact same method used by Japanese school champions.
Your goal: By Level 5 of this course, you will add 10 three-digit numbers in under 10 seconds.
