Simple way to play Soroban
Understand the structure of the Soroban abacus
- Each vertical bar on the Soroban represents a digit in the number you are calculating. The beads on the bar are divided into two parts:
- Upper bead: each bead has a value of 5.
- Lower bead: each bead has a value of 1.
- When the bead is pushed to the central horizontal bar, it is counted in the total.
How to move on the abacus
- Number 7 = 1 bead on 5 + 2 beads on 2
- Number 3 = 3 beads on 3
- Addition: Move the beads according to the value of the number to be added. If it exceeds 9, move the bead to the corresponding left bar.
- Subtraction: Push the beads away from the center bar according to the value to be subtracted.
- Multiplication and division: Work by digit, combine multiple addition or subtraction steps, or apply advanced methods once you are familiar with Soroban.
