Abacus For iPhone - A Simple Soroban Abacus
Detailed App Info:
Application Description
A simple soroban abacus that also shows the number representing the value of each column.
An abacus is a tool that has been used since ancient times to calculate. Calculations with numbers in the millions have been performed using the abacus, showing that it is a powerful tool.
The reason that I wrote this app, is because I have read that mental math can be performed incredibly accurately by those who have mastered the abacus. And after witnessing some incredible mental math skills by a person who has used an abacus during his early years as a salesman. I decided to create a "beginner's abacus" based on the soroban abacus, which is a Japanese variant of the abacus.
I dedicate this app to my code brothers who have just graduated from high school on March 31st. I wish them well, and I hope this app will be of use to many people who are starting some interest in the abacus.
[ Usage ] :
= swipe up/down on the beads to make them move.
= Shake the device to reset the beads.
= Numbers on the top show the "actual" numbers of each column
