      Advantages

      Disadvantages

      It is outdated and not really suitable anymore as better ones can be found at similar prices.

      This was the very first scientific calculator I ever owned, many years ago. At the time I had just started high school and had only just been introduced to more complex mathematics where a basic calculator just wouldn't cut it hence why I needed one with more functions.

      At the time, the calculator was about £10 from any stationary shop. I believe I got mine from WHSmiths but this model is now only available online, usually through re-sellers, as it is a very old model. It is now priced at around £5 and it can only usually be found used.

      I was expecting there to be a huge step up in the complexity of the calculator when I was only used to ones with numbers and basic operators, however I got used to it surprisingly quickly and easily which helped me a lot when there were so many other things I had to get used to at the time in terms of my education - the last thing I needed was not being able to use a device which is intended to made my life easier!

      The calculator had a variety of functions and modes, many of which I never actually got to explore, such as squaring, rooting, modulus, trigonometry and so on. However, the features on this device come no where near to the amount that are now available on later models. For this reason, people who are doing very high level mathematics may find that this calculator is not suitable to them as it doesn't offer the functionality they are looking for.

      The display by today's standards is pretty poor as everything was in-line and functions such as putting something to the power of 3 would be denoted by "()^3" instead of superscript which we see on today's calculators. When you have long equations, all of these unneccasary symbols becomes confusing and can get in the way.

      The battery life of this calculator is theoretically unlimited thanks to being both battery and solar powered. For the few years I had it, before it being stolen, there appeared to be no fading of the display which indicates it running only on solar power.

        Advantages

        Disadvantages

        Very useful for what I needed it for

        When I was at university this was the calculator that I had used. I needed a calculator which did more than just the basic functions like add, subtract, times and divide. This calculator give me different options and this is why I purchased it. It seemed to be better than other calculators at a similar price so it was an easy decision in the end.

        Price

        The price for this when I purchased it was £14.99, for a calculator like this it is a very good price and I wasn't fussed about paying this at all. With the model being a bit dated I am sure you could get one of a better standard or if you wanted this you could get this for a lot less if they still do it.

        Description and Usability

        The calculator is easy to understand if you know exactly what is on it. It is a nice design with buttons in an easy enough position to use. This is pretty much for people that need to do more things than the basic. It has things like x2,x3, Tan, Sin and Cos. I won't go into further detail because this could get a bit confusing for some people I am sure. If you are looking for just a calculator then I do not recommend purchasing this one as you will find buttons on it that you just don't have a clue what they can do.

        Overall

        If you are in need of a calculator for whatever your taking at college or university then this is a very hi-tech one. As I stated earlier this is for a person who is needing the calculator for something which is a bit more complex than just a simple calculator. I found that this helps a lot in doing things you just simply can not do with a simple calculator. Would definitely recommend this as it is very useful.

          Disadvantages

          Great all round calculator

          Calculators... can't stand the things, they remind me of school maths exams and trying to remember the general pointlessness of Pi and its numerous decimal places (sorry if I've offended any of you crazy maths nerds...). Although the majority of computers these days have calculators built-in, I still prefer the portable old-skool variety which you can carry around with you and do your sums on the go.

          Now, when someone asks us to name a calculator brand, 99% of us will answer "Casio" - the Japanese electronics firm has been making mathematical instruments since 1946, with their first electronic calculator (the '14-A') released in 1957.

          My current calculator is Casio's fx-82, a fairly small solar-powered model which can be purchased for £15 from Amazon. Measuring 15 x 8 centimetres, the calculator sits comfortably on a desk without taking up too much space. There are thirty-nine buttons on the device in total - the bottom half being the standard numbers and basic functions, with the top portion representing the strange mathematical symbols which I haven't got a slightest clue what they mean... there's tangent, log, hyp, sin-1 and many, many more - all things which I wouldn't use in my wildest dreams (not that i'd have wild dreams which are loosely based around mathematics...). If you want to hear about the calculator's full potential, then it's capable of "Trigonometric and inversely trigonometric functions, conversion of polar coordinates, hyperbolic and inversely hyperbolic function calculations in new degree and old degree, and curve measure conversion of sexagesimal in decimal and inversely automatic break computation" - did that make sense to anyone!?

          The number keys are nicely spaced out and in easily accessible positions, and the 'On' and 'Cancel' buttons are coloured red to avoid confusion. The fact that it's solar powered means that you don't need to worry about replacing batteries, and the overall feel of the device is robust and well made. The calculator is lightweight at only 47 grams, which makes carrying it around very easy. Although the screen of the fx-82 is pretty small (5 x 1 centimetres), it's clear to read even in bright light - you can even do that schoolboy joke where you type in '58008', and then flip the calculator upside down to reveal a naughty word - how immature...

          Overall, the Casio fx-82 is a decent little calculator which I have found to be reliable and easy to use (barring the technical functions) over the course of the last ten years - recommended.
