Abacus Trainer: Learn Soroban

Learn how a Japanese abacus represents numbers, then move the beads yourself.

Follow eight guided lessons covering digits, place value, addition, subtraction, exchanges using five, carrying and borrowing. Watch each demonstration one bead action at a time, then try three checks at your own pace.

Practice with ten-question sessions in Addition, Subtraction or Mixed mode. Start with Foundations for direct bead moves from 0–99, or choose All Basics for numbers up to 999 with exchanges, carrying and borrowing. Hints and answer guidance are available. Results separately count answers correct on the first check and questions where help was used....
