Description
■ What is flash anzan?
Flash anzan is a "soroban-style" (Japanese abacus) way to do mental math: numbers flash on the screen one after another, and you add them up in your head. No abacus experience needed — start at the beginner level and work your way up.
■ Who it's for
Kids and students who want faster arithmetic
Soroban / abacus learners practicing for tests
Adults who want a quick daily brain workout
Anyone looking for a habit they can actually keep
■ Certification-based ranks
Question count, number of digits, and flash speed are designed around flash anzan certification standards. Begin at the entry grades, pass a promotion exam, and your rank goes up — from your first dan all the way to 20th dan. Your skill is shown clearly as a real rank.
