## What are calculators and how did they come about?

Calculators are used to make mathematical calculations. These machines were invented by a French mathematician, Blaise Pascal, in the 17th century. Calculators have changed over time into something that is fast, easier to use, and more convenient. They were not always easy to use or simple. Blaise Pascal’s calculator was simple enough for the average person to understand and operate, but at the same time it was complicated and tedious. The only way to communicate with his machine was by using a complicated and long process of signals by hand.

Pascal’s calculator used letters to represent numbers. There were no other means to convey his message. If he wished to express twenty-five he would have to write down two five-letter groups and then use a staff, a system by which a piece of wood with letters was used in front of the person making the calculation. This complicated process is summarized in the table below:

Coded signals: ____ ___ ___ ___ ___

Message to send: twenty-five

Step 1. Write down three five-letter groups, each using one type of signal. The first letter signifies that you want to multiply by five, the second letter signifies that you want to multiply by fifty, and the third letter signifies that you want to multiply by five hundred. After this process the message would look like this: _____ __ __ __ __

## How have calculators evolved over the years, and what impact have they had on society as a whole?

Calculators have evolved over the years in order to make them more user-friendly. They have gone from being only used by scientists, mathematicians, and engineers to be used by almost everyone. Today’s calculators are much easier for non-technical people to use and understand than the calculating machines Blaise Pascal invented. These machines were also more expensive and took longer to use. The price of calculators has constantly decreased over the years, and they can now be bought very cheaply. These changes mean that calculators have become far more useful to a wider range of people, especially the young. They are used by young people for their SAT tests and financial problems, as well as by adults for their taxes.

Pascal’s calculator was invented in 1642. This machine needed to be attached to a desk; it weighed over 50 pounds and cost about 500 francs. It could only add and subtract numbers, but it was able to handle fractions accurately. These machines made calculations quicker than handbooks, but this machine was very complicated for non-technical people to use.

Calculators can be very helpful in determining an exact number of seconds that have passed from one time to another. This allows for a much more precise representation of time. It can be used in telephones to tell you exactly how long you have been on the phone. This was not possible with the clocks that existed before.

## What are some of the most popular types of calculators available today, and why are they so popular among consumers and businesses alike?

Some of the most popular types of calculators that are available today are graphing, scientific, and programmable calculators. They are popular among consumers and businesses alike because they are capable of performing a lot more complicated equations than simpler models. They can also be used for things such as graphing a function. The graphing calculator is particularly useful for this. The programmable calculator is the most expensive of all calculators, but they are available in a variety of grades or prices. These calculators are capable of functioning as a personal computer by using a program card. This allows the users to handle several calculations in one program and then print out the results.

Some of the most popular types of calculators available today are graphing, scientific, and programmable. These calculators are extremely useful in the classroom and for business applications.

Graphing calculators are the most popular type of calculator because they can perform complicated equations that simple calculators cannot. They can also be used to graph functions by following a number line from one point to another. The graphing calculator is particularly useful for this. The scientific calculator is capable of performing all the same calculations as a graphing calculator but it is simply more durable. The scientific calculator also has more memory than a graphing calculator. The programmable calculator, which is the most expensive type of calculator, is capable of performing calculations in addition to its other functions. The program card allows the programmable calculator to function as a personal computer since it can run programs and print out results.

## How will calculators continue to evolve in the future, and what new features or functions can we expect to see in upcoming models?

Calculators will continue to evolve over the years, and with these new developments, calculators will become even more useful. Scientists are developing new models that will do an even greater amount of calculations and data calculations. These machines have the capability of performing a wide variety of mathematical calculations, in addition to storing information such as temperature and other statistics. These programs can be easily used by businesses, schools, and governmental agencies in many different fields. Businesses will be able to use them for financial problems involving loans or leases, taxes or insurance policies; .

Scientists and mathematicians also use calculators to make complex calculations in the fields of engineering, architecture and physics. Many calculators even have graphing capabilities which allow students to plot many different types of functions and to find points of intersections or maximum or minimum values. Graphing calculators can be used greatly in mathematics classes both in high school and college. They can be used to find out information about how a certain mathematical equation changes with different variables. This in turn allows students to see how much change will occur when a certain input value is changed.
