Japanese Abacus SOROBAN

Excellent . Now I understand what I have to do. Look for the small white numbers at the top of the soroban and add or subtract from the running total. The calculation is continuous against time. It appears to only give you practise in addition and subtraction but it's OK.

my name is David from this game is asm

Best

the game starts and all you get are numbers, with nothing telling you what to DO with them. Do I ADD, subtract, multiply, divide ???
