مقارنة بين المعداد الهندي
والمعداد القديم
Sliders
العداد القديم
Beads and background are of constant colours and there is no differentiation, which is the biggest weak point in this version of abacus. Photographic / visualization not so strong and much stress to eyes felt by children.
العداد الهندي
Sliders are chosen to hide and unhide the value positions, displayed through the colour images (red and green). Visualization / Photographic memory possible at its best. The images are of bright and contrast colours. There is absolute clarity and the stress free learning.
