💡 How to Use the Abacus

👉 The abacus has 3 rods:
- Left rod = Hundreds
- Middle rod = Tens
- Right rod = Units

👉 Click a bead to move it up. Each moved bead counts as 1.
👉 Count beads and calculate:
- Beads on hundreds rod × 100
- Beads on tens rod × 10
- Add beads on units rod

👉 Match the total with the question!
