Simple Soroban

3,167

This application is a simple Japanese abacus (soroban / そろばん). It has a free mode where you can use the abacus freely, and a challenge mode with 4 operations (addition, subtraction, one and two digit multiplication, and division) and 3 difficulty levels (easy, medium, hard) where you must race against the clock to perform calculations.

Contains tutorials for:
* basic concepts
* addition
* subtraction
* one-digit multiplication
* two-digit multiplication
* division

Also has a custom challenge mode where you can set the number of questions, type of questions and difficulty.

(This is just a hobby project I'm doing for fun. This app is free and doesn't have in-app purchases or ads).
