It was designed in such a way to calculate up to limitless precision The Chinese call it the 2:5 abacus, based on its structure. Typically made of hardwood, the Suanpan abacus was 20 cms long. Since then, they have started using it as the main mode of calculations. That is when the Chinese termed abacus as the “ball arithmetic”. Undoubtedly, It was widespread towards the end of the 16th century. The Modern numbering system was based on Hindu-Arabic mathematics. It was eventually a failure because of its construction. However, this invention was quite a complication to the calculations since it had two beads on the upper deck. The ancient Chinese abacus, called SUANPAN, was developed in the twelfth century and did not attain fame till the fourteenth century. As time passed by, with the advent of modern technologies, the Romans switched to micro calculators in 1974. The lower grooves marked the place value from tens to millions. The beads in the upper groove marked the place value of fives. The last two columns were used for the Roman mixed- base math. On the other hand, the lower ones had four beads. Their Abacus kit consisted of seven long and shorter grooves. Also, they called the counting board Calculi. The Romans used Abacus to calculate, by using the Roman numerals.

However, there are no facts that support the confirmed statement about the invention of the abacus. The design of abacus kits remains to be in a combination of rods and pebbles. Time, people and technology improved the abacus. As time passed by, the design of an abacus kit has widely varied in terms of style, size and material. Countries like Taiwan, Korea, Malaysia and Japan were smitten by the abacus fever.
