## What is an electronic calculator?

In order to perform not only basic arithmetic operations but also the complex mathematical operations, an electronic calculator is used & this calculator can be termed to be quite small besides being a portable electronic device. It was way back in 1960s that the 1^{st} solid state electronic calculator was invented (or you can tell created). And it was then that the era of building or creating some of the extensive history of tools like that of the abacus came in to being.

This abacus was developed somewhere around the 2000 BC whereas a mechanical calculator was developed way back in the 17^{th} Century AD. More importantly this was developed along with the analog computers of the present day. In addition to the ones stated above, these pocket sized devices came to be available in 1970s. However, one could see that such calculators were brought forth sometime after Intel developed 1^{st} microprocessor for Busicom, a Japanese calculator company. With time, the Oil & Gas Industry started using these calculators.

On the other hand, the computer operating systems which dates back to the Unix days were a part of the interactive calculator programs like that of the hoc & dc while the calculator functions means PDA – type devices. But as far as the modern electronic calculators go, they basically differ from being quite inexpensive to being in the built – in form in the printers which would come along with those sturdy desktops.

However, as the world grew so did the market for calculators (grew). And to meet the demands of the problems & the solutions, scientific calculators were included to the list of the calculators in order to continue giving their helping hand to not only the statistical but also the trigonometric calculations. Apart from this, there are those other calculators which have been for the fact that they are able to do the computer algebra stuff.

If you wish to have the graph functions defined that too on a real line or for that instance the higher – dimensional Euclidean space then the graphical calculators are put in to use. Another aspect of these calculators is that although the basic calculators seem to be not so expensive but when the question is about the scientific or the graphing models then they tend to be a bit highly priced when compared to the basic calculators.

### What is the design of a math calculator?

As for the math calculators, the design of such a calculator is inclusive of the input followed by the display output. Besides this, the other aspects which play an important role include memory, power source & the key layout.

## How to use an online math calculator?

To make use of an online math calculator is a childâ€™s play. As, all the user will have to do is punch in the required keys on the keyboard or you can click on the screen because this would be a better idea to know the result.
