When a man needs more computation. Whether it's mathematics. Or science Mathematicians and scientists have invented a device. To bring help to count and calculate. And when, about 2600 years before the Christian era, the Chinese have invented count. This is the first calculator called Abacus (Soroban or Abarcus) for use in the calculation is quite simple. Abacus and a calculator that is widely used today. The behavior of the abacus Use counting Which is the basis of Digital computer (Digital Computer), but also disadvantages abacus is not able to calculate it is not checked. Man trying to find a way to force. By creating a computational tool types up to the year 1617: John Boone in Orlando (John Napier) mathematician Scottish Highlands. Has created a device that helps in removing the root, multiplication, division or easier. This device is called Table logarithmic or Napier's bone in later years: William out of Szeged (Willium Ougtred) British mathematician has produced Ruler Calculator (Slide Rule) to assist in the multiplier, which are most commonly used in engineering and work. Science in 1623: Belk's Pascal (Blaise Pascal) philosophers and scientists through France, which has been known in history as the pioneer and inventor calculator. World's First It is a machine that can be positive and negative, in the form of a decimal number. The gear ratios are well placed eighth in parallel to the landscape. The position of the wheel is visible from the outside. The number will appear on the cover reels. Each band will have a backlash on the 10's, each of which will represent one-digit numbers, so that when a gear rotates 10 will start at 0, then make the next gear to rotate the main one, which is Tdelk to it. The work of this adding machine. The principle is the same as the distance measurement. As shown on the dial General Motors in the year 1646: Scotland's Richard Wilhelm wind lip Venice (Gottfried Wilhelm Leibniz), American inventor. Has invented a calculating machine which can multiply. Divide and square root Run this tool that R. Ritter meter module (Arithmometer Machine) , then hundreds of years. Evolution journey continues. Until the era of William Viet number Shamrocks (William Seward Burroughs) was invented in the calculation. First up And filed a patent application in 1885 for the 'Calculating Machine', which was patented in 1888 and has built a system of calculation for the banks in that period came after William died, the company of his family, he continued to develop. Complex calculations increasingly patent image. The world's first calculator of Burroughs developed and developing computational tools of ancient people in those days were so many people. Get inspired to innovate. Finally, there is something new Occurred during the year 1970 or 42 years ago that the company that invented the world-renowned technology companies like Texas Instruments, Incorporated (TI), first created in 1966 by a team of highly Jerry D. Merryman, James H. Van Tassel and Jack St.Clair Kilby, all have been inspired by the imagination and the idea of people coming past. Almost capped
