When having a layman’s look at abacus all we see is a rectangular case with beaded columns. But these beads and columns, have way more significance. To start with, each column represents the place value beginning from the column in the right, its place value starts from unit, tens, hundreds, thousands and so on. In case, we need to calculate decimals up to two places then, we can start with the place value of decimals from the left end and then continuing the same pattern for units, tens, etc. Beads on the other hand, represent the number value in the place value column. The topmost bead out the five beads in each column represents number value of 5, whereas the other beads have the number value as 1.
Therefore, starting with the first column as unit’s place, one bead represents 1 and two beads as two, but for the second column, one bead would become 10 and two beads would become 20, with similar values considered for the following columns.
For a column, when considering number value as 5, the topmost bead is selected whereas, for numbers greater than 5, we eventually add the beads one by one to increase the number value. For example, 6 is top bead + 1 bottom bead. And after, the number value of a column reaches to its highest value i.e. 9, then the next number is carry forwarded to the next column and the entire cycle is repeats itself again for each place value.
