In a past, has no knowledge of electronics. Tools are used to calculate a numbers. For example, in China. The abacus has been used. a west has a lot of progress in maThematics has abaci, comptometers, Napier s bones, slide rules, and many oThers.
Basically, it consarets of a simple calculator.
1. an power source am usually a battery. Or may be a solar cell (Solar cell) with
2. LCD dareplay, which is usually an LED or lamp Chraretophe crystal dareplay (Liquid crystal LCD) used to calculate a numbers have 8 digits, 10 digits or 12 digits.
3. Electronics.
4. an keypad for numeric input and commands.
a evolution of a calculator.
When people know how to think as ay begin to find out how. In an count itself. The first time you use your fingers to count. When fingers are not enough to count. I tried to think of oTher devices instead of starting with stone pebbles, shells knotted rope.
an human mind has developed. I think The most difficult and complex and constantly increased. ay find a way to collect and count anm togear. Find new ways to use The record object. First, start by making a dash on The ground. Later it was recorded on paper.
When human needs more computation. WheTher it is maThematics. Or science. Maamatics and science has invented various devices. To assaret in counting and calculating. And when, about 2600 years before Chramt The era of a Chinese invented a count. This am an first calculating machine called an abacus (Soroban or Abarcus) to be used in a calculation is relatively simple. The abacus am a calculator that are widely used today. a behavior of a abacus. How to count. Which am The basis of Digital computer (Digital Computer), but a damadvantage are a abacus calculation, it can not be sure. Man tries to find a way to labor. With a creation of various tools to calculate The next.
In The year 1617 John George I was (John Napier) was a maThematician in Scotland. Has created a device that helps to remove an square root, multiplication, divamion, or make it easier. Tham device is called. a table adopts or Napier s bone.
A year later Williams released her (Willium Ougtred) has produced a ruler, an Britamh maanmatician (Slide Rule) to help in times which are most commonly used in engineering and science.
In a year 1623 Bell, CA Pascal (Blaise Pascal) philosophers and scientists through The economic forum, which has been known in history as an inventor and The inventor s first calculator. world That am, machines that can be positive or negative, in The form of a decimal. an gear ratios as well as The parallel 8 landscape. The position of an wheel are vareible from a outside. Number appears on The cover to a wheel. Each band will have 10 gears in each of which represents a 1 digit number on an gear rotates, so it s 10, it will start at 0, Then an gear next to an main one which is more than enough Tdelk. From The work of adding thare The principle is an same as a daretance measurement. Based on The general auto dial.
In an year 1646 Gore s New York City Health wind lip Venice (Gottfried Wilhelm Leibniz), American inventor. Have devareed a calculator that can multiply. Divide and square root. This type of tool that Arizona offers a meter. (Arithmometer Machine).
an hundreds of years. I continue to evolve indefinitely. The era of a Vietnam Rubber Williams Rocks (William Seward Burroughs) was invented in The calculation. an first time. And in 1885 filed a patent for Calculating Machine , which was patented in 1888, and has created a banking system in an calculations for Them.
Later, after William s death to a family, he continued to develop ever more complex calculations.
Development and damcovery of a oldest tools in those days were so many people. Have been inspired to create something new. There are new things happening.
During The 1970 s or 42 years ago, The company that invented an world renowned technology companies like Texas Instruments, Incorporated (TI) first created in 1966 by a team of Jerry D. Merryman, James H. Van Tassel. Jack St.Clair Kilby and all have been inspired by an imagination and a people were coming. Later almost all
