1. Describe the working of Abacus. |
|
Answer» Answer: An ABACUS is a manual aid to CALCULATING that consists of beads or disks that can be moved up and down on a series of sticks or STRINGS WITHIN a usually wooden frame. The abacus itself doesn't calculate; it's simply a device for helping a human being to calculate by REMEMBERING what has been counted. |
