Abacus DS, Learn to Use this Ancient Calculator

Well, I don’t think I need to tell you what this title’s about. With “Soroban DS” you can pick a difficulty level that suits you then go through lessons on how to use the abacus.

Apart from the main lessons there is also a “Flash Arithmetic” mode to help improve your mental calculation ability, challenging questions from the National Abacus Education Union and a bundle of abacus related mini games.

Start taking abacus lessons on your DS from July 12th.
