Addition on Abacus

Let's see step by step representation of addition on the abacus:
Input your initial range. Say you've to feature 1234 and 5678. Enter 1234 on the abacus by pushing up four beads in the one's place 3 in beads tens place, 2 in the hundreds place 1 in the thousands place.  
Start adding from the left.
The first numbers you will add are the one and five from the thousands place, during this case moving the one bead from the highest row of that column right down to add the five, and feat the lower bead up for a complete of half dozen.
Likewise, to feature half a dozen within the hundreds place, move the upper beads within a hundred column put and one bead from the lowest row up to urge a complete of eight.  

Complete an exchange. Since adding two numbers in the tens column can lead to ten, you will carry over a 1 to the hundred places, creating a nine in this column.
Next, place all the beads down within the tens place, leaving it zero.  
In the one's column, you will be an equivalent 8 and 4 equal twelve. Thus, you will carry the one over to the tens place, creating it one. You will have 2 in the one's column.  

Count your beads to urge the solution.
You will have.  6 in the thousand's column.  9 in a hundred column, a 1 in the tens, and a two b in the ones: one, 234 + 5,678 = 6,912.  

Summary

 To use an abacus for addition, first, set it to zero by moving one or two beads to the top of each row and four beads to the bottom.
Assign each column a place value, such as the farthest right column for ones (1-9), and the next column for tens (10-99). If working with decimals, designate the farthest column as the tenths place.
To add numbers, start by pushing up the appropriate beads in each column to represent the first number. For example, to add 1234 and 5678, push up four beads in the ones column, three beads in the tens column, two beads in the hundreds column, and one bead in the thousands column to represent 1234.
Next, add the second number, 5678, by lowering beads from the thousands place. Here's a visual representation of addition on the abacus.
