Colour and non-Colour position
العداد القديم
The Same is not possible here because of the non-colour position of the beads. In the old abacus where the beads are homogenous / uniform in colour and therefore distinction between the value and non-value beads is very difficult. Further the non-value beads tend to disturb the vision and the abacus practitioner has a blurred vision of the value beads and the values.
العداد الهندي
In the Indian Abacus, the colour and non-colour positions of slider positions remove the confusions and the disturbing view. The features mean either value or no value positions which are clear and understanding & memory registry are easier.
