【How to Use】
Visible Mode
• Instead of moving the beads up and down, you operate by touching (on/off).
• Use your thumb for the yellow single bead, your index finger for the orange five-bead, your right hand for the ones place, and your left hand for the tens place to calculate.

Mental Arithmetic Mode
• Touching the icon in the upper left corner switches to "Mental Arithmetic Mode," where the beads are not displayed when you touch them.
• Visualize the shape of the beads in your mind and calculate, then check your answer using the "💡" button at the top when you're finished.

*This app does not include a math problem-solving function.
