The first adding machine was first used in the United States of America to calculate basic dollars and cents. These machines were able to perform addition and subtractions directly and multiplication and division with repetitions. There were many ups and downs before any company started manufacturing it, but after trial and perseverance the adding machine proved to be a success. That initial success, with what is basically a simple calculator, sparked thought which in turn facilitated visions of a new approach to audit and control which in turn drove the development of the basic adding machine into more process specific tools. Let's see how adding machines were replaced over time by new instruments as calculation methods became easier to integrate and support specific process and activity.

They say necessity is the mother of invention, but it was a bit different in the case of the adding machine, which was invented out of boredom. The first adding machine was invented by William Seward Burroughs during the early 1880s and was filed for patent in 1885. He was the son of a mechanic and had worked with different machines since his early childhood.

Burroughs grew up to be a bank clerk who was not happy at all with his job, especially because of those hefty manual calculations and long working hours. He quit his job due to bad health conditions and joined a machine shop. The fusion of knowledge of the long process/repetition involved in the clerical activity and his honed skills with machinery allowed him to conceive, develop and invent the adding machine.

This machine was the first of its kind, massively improving on manual tools which included arithmetic tools like the abacus and adders. With time, adding machines grew to include a full keyboard and were able to print the numbers and sums, becoming a key component of modern accounting and in common use in banks and businesses. These machines were used in most banks until the introduction of electronic calculators in the 1960s.

The very first calculator that could be held in one hand was invested by Curt Herzstark in 1945. This first hand held calculator was a mechanical calculator and its portability meant that activity could take place whilst on the move (on a train etc.). Although rlatively heavy and bulky compared to modern calculators, it was produced and consistently used until the lighter, more user friendly digital calculators, the first made by Japan, came into existence in 1970. As people becamce more familiar with the electronic calculators and the costs reduced, the demand for mechanical calculators faded away and they were replaced with advanced calculators as you know today.

Electronic calculators were first produced after the introduction of the transistor in the early 1950s. These early electronic calculators used to run on vacuum tube technology and were introduced in 1961. First calculator using integrated circuits appeared in mid 1960, which were then developed into even smaller circuits.

This development, born of improving technology was also the cause of shrinkage of the size of the basic calculators, led to the introduction of smaller calculators that were built with a small chip inside and were introduced in the early 1970s.

Today, you don't need a physical calculator to do your arithmetical calculations. All you need is a smartphone or a computer to access a calculator. One of easiest calculators that is available is the Basic Online Calculator by iCalculator.

These basic calculators are capable of doing all the arithmetical calculations, but today online technology has made it possible for us to have a wide range of calculators for numerous formulas and processes required for professional and personal use.

Performing addition, multiplication, subtraction and division is made easier by these calculators. The basic arithmetic calculations are just a part of a very huge concept of mathematics.

The oldest known mathematical development after the basic arithmetic is believed to be the Pythagorean triples or the Pythagorean theorem as we know it. The Pythagoreans were also the people who came up with the term Mathematics.

You can find traces of Mathematics in almost all the ancient civilizations like, Egyptian, Babylonian, Greek, Indian, Chinese, Roman, Islamic Empire, Maya. Travelling through these civilizations the method of instructions crossed Medieval Europe and reached the Renaissance.

The 17th century was the time of the Scientific revolution and Mathematics grew with science together. It was time for Mathematics to spread globally, along with applied Mathematics. Several calculation methods evolved during the 18th and the 19th century.

Today, we have numerous calculation methods that are used for solving different kinds of problems or equations. In the absence of a quick and automatic calculator, using these metrics and comprehending the formulas can be challenging for many of us and some of us might not be able to do calculations simply due to the time taken to compute the functions.

The advancement of adding machines may seem limited to these mathematical calculations, but it goes much beyond that. Finance industry runs and functions with all of these arithmetic and advanced mathematical metrics. Let's see how the adding machine was related to finance and what are the advanced metrics of calculations that are used in finance today.

As we discussed earlier, the adding machine was mainly used in banks but things changed with time and, along with all mathematical metrics and techniques, finance grew. This is because humans use finance to calculate money and calculating money is pretty important to us.

Just like Mathematics, finance has several branches, and you have used many of them whether you are aware of the separate financial disciplines or not. You might not even be aware that you are in touch with finance constantly.
