Abacus has got the place of great importance in the history of mathematics. One can easily say that the history of mathematics starts with the invention of abacus. Abacus solves the basic arithmetic problems with so much ease and reliability that it is still taught in the various parts of this world in this modern day. Abacus is not like the modern electronic calculators that perform all of the functions of their own and then present the result in an electronic form on their screens. It is rather a tool that helps in counting the numbers with the help of reference in its beads. The beads of the abacus help in remembering the numbers counted and thus make the calculations very easy to perform. This attribute of the abacus has caused it to stand high in the history and made a significant place for it in the lives of people throughout the history.

The Roman numeral for five is V and the numeral for one is I. Five is V, Six is five plus one or VI, and Seven is six plus another one or VII.

An abacus. The roman abacus worked on the same principle as the Japanese abacus, but looked very different. The Japanese one had a number of beads strung on wires, grouped in twos and fives. The roman one was a small slab of stone, with small round depressions cut into the surface. These were arranged in straight lines and grouped in twos and fives. The Romans put pebbles into the depressions, and manipulated them in just the same way as the Japanese did their beads, though rather more slowly. If you know roman numerals, you will know that they are grouped in twos and fives. Incidentally, the latin word for pebble is calculus. So, the word calculate . . .

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
