Indian Abacus at Anna Nagar

            Salient features of the products is, Unhide and hide the colour images:  The          student while operating this Abacus moves the Lower and the Upper sliders to unhide and hide the colour images which represent values. 


The display of colour images and specific values makes the visualization many times better, stronger, faster, stress free and error free calculation, when compared to the earlier Abacus.
