Overall development with abacus. This machine could add and subtract two numbers directly and multiply and divide by repetition. In Japan and China, Abacus competition is a big thing. The abacus is now available in the form of a portable computing device. Surviving notes from Wilhelm Schickard in 1623 reveal that he designed and had built the earliest of the modern attempts at mechanizing calculation.

A calculation tool used by sliding counters along rods or grooves, used to perform mathematical functions. The beads above the horizontal crossbar are known as Heaven beads and the bottom one is known as earth beads. Each rod can represent any number between 0 to 9 that is 10 numbers. The standard abacus can be used to perform addition, subtraction, division and multiplication; the abacus can also be used to extract square-roots and cubic roots. The smaller groove’s beads were denoted as five units, five tens, etc. Nowadays, abaci are frequently constructed as one having a bamboo frame with small beads sliding on wires. However, the reason why abacuses are still being used and taught in schools today is that it helps children to enhance their mental arithmetic skills instead of relying on machines and devices to calculate for them.

Old Babylonian scholars such as Curricio believe that the old Babylonian used their sexagesimal number system in Abacus to calculate. Between 2700bc to 2300 bc, Sumerian used the first abacus to count. Use of an abacus to solve mathematical problems is no surprise. There are many kinds of abacus present but the Japanese abacus or soroban is the widely used one. Fig.Photograph of Salamis tablet. It is a calculating device which is widely used in the eastern countries in the ancient times. Abacus has traveled a long way and had transitions as it traveled through different countries. By relying too much on electronic devices, children are unable to learn math properly as most calculators do not show how they reach their final computations. The bead on the upper deck has the value five and each bead of the bottom deck has value one.

In 1820, a device in a patent filed in France by Thomas de Colmar, became the first commercially viable counting machine. This new award will be called the IMU Abacus Medal, and will be awarded at the International Congress of Mathematicians for the first time in 2022, and will continue to include a cash award of €10,000 and a medal. This was requested by a primary school teacher. The abacus essentially consists of a number of rows of movable beads or other objects, which represent digits. When it traveled from one country to another it transited also. However, the exact design of this suanpan is not known. From 5000 years ago to this 21st century, the abacus went through many transitions. The slide rule is basically a sliding stick (or discs) that uses logarithmic scales to allow rapid multiplication and division. The abacus is a mechanical aid used for counting; it is not a calculator in the sense we use the word today. The calculator is proven to be much more convenient to use than the abacus, as the electronic device calculates the total value for you as opposed to the abacus, where you still have to compute the numbers on your own. The two beads indicate that the value of the second line is at 2, but since it is at the second column, we must add a 0 next to the 2, which means that the correct value is 20.
