How abacus works?

Abstract numbers are converted to concrete images / pictures which help children to understand numbers, number concepts and basic operations easily.

As illustrated below, the Indian Abacus, or abacus, is a calculating instrument with a number of counting slider / beads that slide back and forth along column / rods.

A crosswise bar (center bar)  divides the  Indian Abacus into two parts. The  upper  part  consists of a row of the  “5” value slider / beads and the lower part consists of  four rows  of the “1” value slider / beads. Every single slider / bead above the bar has the value of “Five" and  the beads  below  the  bar  have the value of “One" respectively. The columns toward the left always have higher digit values (1, 10, 100, 1000 …) than those toward the right.

Dots are to be used to indicate the unit point of numbers or a decimal point (after the pointer / first digit of right side is meant for decimals).
