The various types of calculators you can choose from

The calculator is a device that makes it easier for people to compute large numbers and arrive at the right answer. More often than not, people end up making errors while performing basic mathematical calculations as well. Therefore, there are various calculators such as electronic organisers and many more that are available today for people to choose from based on the nature of their job.

While a simple handheld calculator is ideal for businessmen, it is probably more suitable for scientists and people in professions that involve compound calculations to have at hand a good digital organiser. Before you choose the most suitable one to match your needs, it is better to increase awareness about the options available to you so that you can make the right choice.

The first mathematical contraption to come into use was the abacus. This was a very simple calculating aid that was made using stones or beads which were used to represent the numbers. William Schikard, in the year 1645, invented the first machine for calculations. This machine was initially used to perform astronomical calculations when it first came into existence. The first calculator that was created to perform simple addition and subtraction was created in 1645 and called Pascaline because it was created by the notable inventor Blaise Pascal. He created this machine to decrease his workload which involved a lot of computation. Though it was unlike the calculators and electronic organisers available today, it was considered a useful machine then.

Commercial calculators were introduced to the world only in the 19th century. Many people made improvisations to the device that was created by Pascal and this led to the birth of different types of calculating machines. The calculating machines that were in use till the second half of the 20th century could only perform basic calculations. It was only during the latter part of the 20th century that these calculating machines underwent a huge transformation to perform compound calculations as well. Electronic organisers, financial calculator, graphics calculator and many other types of calculating machines came into existence during this period.

Most calculators and electronic organisers worked only on battery up until a few years ago, where today they are powered using solar cells. Considering the need to conserve electricity and harness the potential of renewable sources of energy, an increasing number of people prefer the solar powered calculating machines.

In modern times, life without calculators has become unimaginable. These calculating machines are used not only by businessmen, traders and people in other professionals, but also by students in schools and colleges. Electronic organisers are used extensively by people working in the field of science and research to compute complex numbers. There are a number of calculating machines on the internet as well that can help you calculate anything under the sun, ranging from the due date for pregnant women to the amount that you will have to pay as EMI  if you avail any type of loan. Grade point average, calories consumed and the calories burned during your workout can also be calculated using these devices.
