1. What is Chinese Abacus Calculation?

The Chinese abacus (suanpan) is an ancient calculating tool that uses beads on rods to perform arithmetic operations. It has been used for centuries and remains an effective method for manual calculation.

2. How Does Abacus Calculation Work?

The abacus consists of beads arranged on rods, where each bead represents a specific value. The calculator simulates manual abacus operations for:

• Addition and subtraction of numbers
• Multiplication and division operations
• Decimal calculations

3. Importance of Manual Calculation

Details: Learning abacus calculation improves mental math skills, enhances concentration, and provides understanding of fundamental arithmetic principles without electronic assistance.

4. Using the Calculator

Tips: Enter two numbers, select the desired operation, and the calculator will demonstrate the manual abacus calculation process and result.
