**The Calculator: A Brief History of Calculator**

**The invention of the Calculator:** The calculator has become an important part of all of our lives today. The calculator has made calculations extremely easy. With the calculator, not only do students solve big numerical numbers easily but also shopkeepers and domestic women can easily calculate and calculate the transactions related to it.

Considering the usefulness of calculators, nowadays it is also available in smartphones and computers. Where earlier it used to take a lot of time to do big calculations and adding and subtracting numbers was difficult.

Now, with the help of a calculator, it is done in a pinch, but do you know how this calculating machine i.e. the calculator was started and who invented it? If not then read this post.

## Invention and history of calculator

**What is Calculator?**

The calculator is a small-sized portable electronic device used for adding, subtracting, multiplying, dividing numbers, or for any economical operation.

Due to this, even the most difficult calculations can be done very easily in seconds. At the same time, computers are used for big calculations, but where it is not possible to use a computer, small calculations are done with the help of a calculator.

At the same time, calculators have made it very easy to solve math calculations and many questions, so people use the calculator a lot in their daily work.

At the same time, calculators are also available in smartphones and computers. Apart from this, there are many digital calculators available in the market, some of which are powered by cells, batteries and some are solar calculators which are charged with sunlight.

**Who Invented Calculator?**

Nuclear bones or hand-toes were previously used to make calculations, but this became difficult for large calculations, so mechanical calculators were used in the 17th century. The first mechanical calculator was invented by Wilhelm Schickard in 1642, named Blaise Pascal.

Although the 17th-century calculator is used at that time these mechanical calculators were made. In 1642, the Mechanical Calculator was invented by Wilhelm Schickard and the mechanical calculator was named Blaise Pascal. Over time, many changes were made to the Calculator. The nineteenth century saw a lot of changes after the Industrial Revolution and invented the Dalton Edging Machine in James L. Dalton of America and 1948 created the Curta Calculator. This calculator was very expensive but it was easy to calculate large numbers. Electronic calculators started being made in 1960 and it was reduced to such an extent that any person could easily keep it in his pocket. Later in 1970, a Japanese company and Intel together created an electronic device with the help of which any calculation can be done easily and it is very small to carry anywhere and today we use this same calculator.

**Electronic calculators developed after much improvement – **

**Electrical Calculator**

As mankind evolved, so did many changes to the calculator to calculate overtime. At the same time, in the 19th century, when there was a revolution in the industrial world, and there was rapid development, there were many changes in the calculator because of the people’s need.

In the US, James L. Dalton discovered the Dalton Edging Machine and then developed the 1948 Curta Calculator, which was quite expensive, but with the help of large numbers and calculations of data was easily possible.

Subsequently, small size electronic calculators were invented in the 1960s. Then in the year 1970, a Japanese company Busicom and Intel jointly created a modern-age calculator, which can be easily calculated from hard to difficult, and the main thing is that humans keep it in their pocket with them somewhere. Can also be carried, which are still used today.

**Before the invention of the modern calculator, calculations were done like this –**

**Ishango bone for calculation – Ishango**

Around 32 thousand years ago people used the Ishango bone for calculus. The lines drawn on these bones were unique and were calculated through these lines.

2. **Abacus for calculation – Abacus**

It was difficult to make large calculations through these bones. Therefore, AWACS was invented about 2700 years ago to calculate more numbers. It was the first calculating machine, it was invented for the Hindu and Arabic number system. It was made in parallel by placing a small frame made of wood or plastic.

Let us tell you that each rod of this instrument used for calculation has numbers from 1 to 9, in which people used to do big calculations by increasing the frame, although it also took a lot of time to calculate. .

**3. calculating clock – Calculator Clock**

It was built by Wilhelm Schickard in 1623, it was the first edging machine with a multiplying device for multiplication.

**Slide Rule – Slide Rule**

In the 16th century mathematician, John Napier discovered algorithms to solve mathematical questions. There were two types of tracks in the slide rule, which also shifted relative to each other.

**Stepped reckoner (world’s first modern calculator) – Stepped Reckoner**

The stepped reckoner device was the world’s first modern discovery, it is also known as the world’s first modern calculator. It was discovered by Gottfried von Leibniz. With this device’s help, economic operations such as multiplication, division, occurrence, etc. were made very easy.

**Arithmometer (first successful machine calculator) – Arithmometer or Arithmomètre**

In the year 1820, Thomas Day created the world’s first most successful machine calculator, which was used the most from 1851 to 1890. This was largely successful, as it could easily add, subtract, multiply, divide.

**Innovation of Comptometer (equipped with keyboard facility) – Comptometer**

The machine calculator comptometer was discovered in the year 1887 with the keyboard. It was based on the Pascal Calculus machine. The most special thing in this was that it included the facility of printing with modernity.

**Analytical Engine (Programmatic Device) – Analytical Engine**

It was the first programmatic device in the world to function under a programmer.

**Millionaire (used to be very easy to multiply) – Millionaire**

Leon Boli discovered the Millionaire device in the year 1893, with the help of this, any number could be multiplied by another number in a few minutes.

Apart from this, the calculator written below was created before the invention of modern digital calculator and today after many experiments we can use modern calculator, so let’s know about some such calculators –

**6 Different Types of Calculators | On The Basis Of Purpose**

**1. Abacus**

**2. Basic Calculators**

**3. Scientific Calculators**

**4. Graphing Calculators**

**5. Printing Calculators**

**6. Online Calculators**

In this way, modern calculators were used after many inventions, which has made calculating extremely easy. At the same time, it saves tax time in the toughest calculation a few seconds and gives accurate results.

However, we should not use it excessively and should not use it for easy calculations because doing so becomes such a habit of using a calculator, and then there is again a lot of difficulty in doing small calculations.
