One of the advantages of the abacus is that it is easy to use. Another is that it does not require electricity to work. You can use it no matter where you are.
abacus helps us to calculate maths easily
An Abacus has beads and strings.
ABACUS is a name of a calculating apparatus - it is not an acronym.
If you are refering to Chinese abacus their earliest rudimentary design of abacus has 1/4 rod beads (quite similar to the later Japanese soroban abacus). Various other types of abacus design were also seen afterwards, but the advance type of 2/5 rod beads became standard and classic.

They come in various sizes, but a typical abacus is about eight inches square.
Improves maths skilla
China invented the abacus .
An abacus is used as a tool to train children how to perform complex mathematical operations quickly and efficiently. One of the advantages of an abacus is that it gives a color coded physical representation of a number system. This allows a student proficient with an abacus to eventually start performing mathematical operations in his/her head as they can visualize how the abacus would look if they were to perform the operation physically. The abacus has another positive use as it is a good teaching tool to help blind students learn math.It is significant because it was the precursor to the modern calculator. It is a portable device that can be carried on person to perform mathematical operations without the need for a writing instrument or paper.Source: http://en.wikipedia.org/wiki/Abacus
