About the tests
Sums per minute counts every sum you finish in the minute; right first time counts only sums you got without a hint or a second try. Results are saved on this device and shown in your stats.
Flash anzan (Japanese for mental calculation with flashed numbers) is how abacus learners practice picturing the beads. Begin with three 1-digit numbers at the slow speed; when that is easy, add more numbers before making them faster.
