Indian Abacus for students:
This Abacus when the sliders are manipulated reveal colour images
representing numbers / value equivalents.
The projection of colour images was focused to be the very strong
feature of the invention. Colour images
meaning numbers / values form strong stimulus.
The projections of colour images draw the attention of the eyes faster,
easier and in a stronger measure, resulting in the response becoming easier,
faster and equally stronger in the paying of attention. The sliders revealing colour images when
moved towards the bar do not also trickle / fall down in the slots to its
Original position even if the abacus is held upright which is again a new
feature which gives the children scope to read well the images keeping the
abacus upright during the initial learning and to also show to the tutor the
final answer to see from a distance.
