What is the first item that you look for when you need to do any calculations? Some people will say that they reach out for their computer, but the majority will still say that it is calculators that they would depend on. Think about this - we are an advanced species that has everything available to make our lives easier. Yet sometimes we still prefer to use those older gadgets to perform some of the tasks. Scientific calculators - contrary to what some people think - have not lost their importance at all. In fact, as we counter more and more complex mathematical calculations, these are gadgets that still deliver a reliable solution, while being the most convenient to carry around with us.

The first of the scientific calculators was the HP-9100A that was released in 1968. The standard calculators came way before 1968. There was a time when people simply couldn't work without them. From students to employees in accounts department to store clerks - everyone had their own calculator to use. Then we saw the advent of computers and with this, the whole world changed. People now started to think that computers could do everything - all calculations, all problem solving and all decision making. The sales figures of the calculator came down.

But things soon reverted back in favour of the calculator as people re-discovered the value of this simple gadget. If you think about it - you cannot open up your laptop when you need to do a simple exponential calculation. And no way can you carry your desktop with you. You have the option of carrying your smartphone but these phones have basic calculators and not scientific calculators. Smartphones, at the end of the day, are for making and receiving calls and not do trigonometric and exponential calculations.

This is where the value of the calculator comes into its’ own and why you will still find so many students carrying their own standard calculators or scientific calculators. These gadgets hardly occupy space and they can be used in a jiffy when someone needs them. Moreover, you don't have to be a master of machines to work on them. Put down the numbers that you need to calculate, then simply press the appropriate button and the value will be there. This can be a much more convenient method than using a computer, especially if you need to do your calculations on the move! It is not difficult to understand why people still use standard calculators and scientific calculators for quick calculations.

Buying standard calculators and scientific calculators has now become very easy thanks to online shopping. There are many websites that sell these gadgets, some of them actually specialise in selling these gadgets. All you need to do is look up the available items and choose the one that you want. If one website doesn't have the model of the calculator you want to buy, then you simply need to switch to another website.

As long as our lives require us to make mathematical calculations, there will always be a place for calculators and scientific calculators. They don't have to cost you a fortune, they are easy to maintain and they do an invaluable job. You just cannot do without them.
