About Anzan Zen: Mental Math
Anzan Zen is a calm mental math trainer built around flash anzan, the Japanese abacus drill: numbers flash one at a time, you add them in your head and say the total out loud. Climb 20 levels, the 10 kyu to 10 dan of the Japanese exam: from two 2-digit numbers up to fifteen 3-digit numbers flashed in 3 seconds. FLASH ANZAN, 20 LEVELS Numbers appear one by one and vanish. After the last one, give the sum of them all. • Levels 1 to 20, from 10 kyu (two 2-digit numbers in 4 seconds) up to 10 dan (fifteen 3-digit numbers in 3 seconds) • Custom: 3, 5, 10 or 15 numbers, 1 to 3 digits, 1.5, 1.0, 0.7 or 0.4 seconds per number The levels follow the Japanese flash anzan exam table. They are not an official certification. One wrong total ends the run. Every level and setting keeps its own record: how many totals in a row you got right. DICTATION Nothing on screen. The phone reads the numbers…
