In the good old days, people had unique ways to calculate things. Items and objects such as leaves, sticks, and even beans were extensively used for calculation purposes. This method, although in use for a very long time, soon became obsolete.
And many times, the outcome of a calculation depends largely on the honesty and integrity of the person entrusted with the role of calculating things.
These conditions eventually led to the invention of a wooden calculator called Abathia. A wooden framed machine came with wires in which the beads were to be assembled for calculation purposes.
Interestingly, these calculators were used for long and easy calculations in offices. But, limited in their functionality, they were sidelined and thus other forms of gadgets came into the picture.
With the economies and technologies growing at a rapid pace, the need had been felt wide and across to have gadgets that could perform all basic functions automatically and quickly.
This lead to emergence of basic calculators that were capable of performing minor calculations like ‘plus’, ‘minus’, ‘multiplication’ and ‘division’. Programmable calculators were later invented to make complicated calculations.
The scientific calculators we see today are the latest inventions in these sections. Now widely used in companies and universities for calculation procedures. With the advent of the Internet, these calculators have been further revised to make them available in the online version.
