@Streak I only know the basic, but the number of beads on a row is you base (10 beads = Base 10)

Each line is another magnitude of digits, so 6 lines can count upto 1,000,000

how many beads pushed a cross represent the value of that digit.

@Streak
It's quite ingenious really.
Every bead on the lines has a set value.
The first set represent Ones
>Then Tens
>Then Hundreds
>Then Thousands
>etc

The set of beads on the side, I am unsure of it's true purpose. I always used it for carrying numbers to help with math.

Anyways.
Say you have the number 124. To represent this on an Abacus, you would slide a 100-Bead, two 10-Beads, and four One-Beads.
Now add 53...
Slide over five additional Ten-Beads and three additional One-beads.
You now have 177.

Does that make sense?

Oh! Right! Now I remember what the side-set is used for
They are placeholders. In some Abacuses, there aren't a full set of 10 beads on the line, so those are used to represent an integer up.
Say there were only 5 beads on the line. There should be two accompanying beads on the Placeholder side, each having a numerical value of 5 (and it's varieties for the other numerical sets)

Its a little complicated, but lets say we want to represent the number 156.
Slide over one 100-set bead, one placeholder-set 10-set bead, a placeholder-set 1-set bead and a normal 1-set bead.

Your highness, I always wondered how multiplication and division operations can be performed on abacus. Can you explain this to me?
