The Mental Playlist

Hello Adventurers, this playlist is dedicated to Mental Calculations where the Answers are 'automatically displayed' after a few seconds, long enough for you to solve each question before its answer gets displayed. These videos will keep your Abacus Mental Calculations razor-sharp long after you have mastered any given concept of the training program. I will keep uploading videos covering every single concept of abacus course overtime. You may increase the PLAYBACK Speed of these videos if you like to raise the bar!
