Mental Calculation and Flush Calculation

​Continued training of Soroban makes it possible to mentally calculate numbers only using the image of Soroban.  This skill is "mental calculation", which does not require physical use of Soroban.


And further continuous training will enable an advanced level of mental calculation, where even no finger movement in the air is needed. 

This calculation skill uses only the clear image of Soroban installed in the brain, in which Soroban counters are freely moved with accuracy to calculate the digits of numbers in a speedy manner.   


Overtime, the learners find his/herself with the ability of flush calculation, where calculation is complete with accuracy only by looking at the numbers pop up one after another on the screen.
