Simple Soroban 2.1.2

This application is a simple Japanese abacus (soroban / そろばん). It offers both a free mode for freely using the abacus and a challenge mode which includes four operations (addition, subtraction, one and two-digit multiplication, and division) and three difficulty levels (easy, medium, hard). In the challenge mode, you are required to perform calculations against the clock.

The application includes tutorials covering basic concepts as well as addition, subtraction, one-digit multiplication, two-digit multiplication, and division.

Additionally, there is a custom challenge mode where you can customize the number and types of questions as well as the difficulty.
