## Let's calculate (1 + 2) on Abacus

Equals Three (3)   Figure (A)
Figure (B)
Figure (C)
1. As shown in figure (A); add one '1' on units rod of abacus, by moving one lower bead towards the bar.

2. As shown in figure (B); add two '2' on units rod of abacus, by moving two lower beads together at a time, towards the bar.

3. As shown in figure (C); Now, count value of the beads that are near and touching the bar it is three '3'.

Let's calculate (3 + 1) on Abacus
Equals Four (4)   Figure (A)
Figure (B)
