Its frame divides two parts, the upper part call heaven, and the bottom part is called Earth.ĪBACUS is a wooden frame consisting of rows of holding horizontal wires and beads in those wires. ![]() This helps to teach counting to young children. This device used for simple calculating like addition and subtraction can feature by moving the beads according to certain rules.
