There was a time when calculation was a huge challenge for mankind. They literally had to dig deep for objects such as beans, twigs, sticks and so on, that would help them add together several constants or variables and arrive at a result. With advancement in technology and man’s mind, man invented devices such as the abacus, the computer and the calculator which would make solving complex numerical and scientific equations simpler. To combine the advantages of a computer and a calculator, online scientific calculators were invented. This form of calculator, not only calculates mathematical equations, but also scientific and engineering ones.

They are usually used in every educational institutions irrespective of which grade. Starting from junior high level to university, students throughout their major academic prefer using online scientific calculators. This calculator is a digital version of the calculator incase one is not equipped with a physical calculator. It is designed with all the features of a physical calculator. **Age calculator** Some websites such as web2.0Calc.com or encalc.com provide handy digital calculators.

A pertinent question asked repeatedly is why do people use online calculators? Most people go online to calculate numerical’s because they do not possess a calculator at hand or are unable to arrive at the right solution manually. With every new technology hitting the markets, there are numerous pros and cons that arrive with them. Similarly there are numerous benefits that come with an online scientific calculators. Some of them are listed below:

Easy to use- Online calculators are the easiest to use. In case, one is a first timer, there are manual or guides to help a novice to make his way through.
