      A cool gadget for science students

      As I am an engineering student I know the value of calculators & it's importance in our study so choosing a good calculator is always an important issue & I always prefer a Casio calculator which is in fact a international company and their gadgets are pretty cool & simple to use also I am using Casio calculators for 4 years now at first I used FX 82MS which was also a good calculator but couple of months ago I just bought this model of Casio and I can see this is a quite improved version than FX 82MS as the display is quite improved & it is little bit easy to use now and it also got a attractive design as well than FX 82 MS though the functions are same as the previous one I used as it has 240 functions it also has 2 line 7 segment display each of line can be consists of 11 digits. So if you are new to a scientific calculator it could be your choice to buy as I have never experienced any bad things while using this calculator. You can also buy this calculator from amazon.uk market place where the prize starts from £6.99+shipping.

        Beats the competition

        As a Maths tutor in my spare time I have to use a calculator on a regular basis. This is the calculator that I swear by and the one that I recommend to all my students and I will explain the reasons for this below.

        Firstly just in case you never went through education and don't know what a scientific calculator is I will break it down for you. It is more advanced than a standard calculator with many extra features including trigonometric features, exponential functions like roots and square roots as well as quick shortcut buttons like pi. It is the standard for all students at GCSE and Alevel maths. Now on to the reasons that is my favourite scientific calculator

        Usability is higher than previous Casio calculators as with this version there are not only left and right arrows but up and down arrows. This might seem like only a minor points however when adjusting fractions it is a blessing and much more use friendly. The fractions actually look like a fraction and you just use that up and down button to scroll between the numerator and denominators.

        The buttons are also much improved with a faster responsiveness than ever before and they have shifted where a few of the buttons are. I don't quite agree in this regard but that is simply as I was used to the old format where all my favourite buttons were. I have got used to the new format but don't particularly find any advantage of where the new buttons are located. I could understand if it saved time but that is not the case here.

        In terms of price this is £7.99 at Ryman's and actually only £7.50 at Amazon however there is a £3 p&p here which makes Ryman's the best value. I have to add that you can buy this off Ebay but of course prices vary on EBay so only use my price as the guide price. This is very good value though and I would be happy to pay as much as £10 for this calculator.

        Overall this is a must have piece of kit when I teach my students and the most comfortable scientific calculator I have ever used. It has clearly been made with the end user in mind and it is clear why Casio has a stranglehold and overtaken Sharp as the number 1 calculator provider.

          Perfect for every day use

          I bought this calculator when I was doing my maths GCSE and since then it has come with me through A Levels, and now I'm using it every day at University. As I'm doing a chemistry degree, we use these for calculations nearly every day and it's never let me down. The model I have has a solar panel and a battery, which gives me extra piece of mind incase the battery runs out or the sun goes in! A cover for the calculator is also provided which protects the front of the device, and also has a sticker with instructions on how to do a few different calculations.

          The calculator has a large and clear display so you won't find yourself squinting to look at your calculations. An extremely useful feature is that you can scroll through your previous calculations to check what you've typed in case you've carried forward an error in the subsequent calculations. You can also use the circular navigation button at the top to scroll through the current calculation and change any numbers without having to clear the whole thing. This is incredibly useful if you've typed in a calculation with loads of brackets, for example.

          As well as the standard Maths mode, this calculator also features a handy Stats mode. To be honest, I never really used this mode until University, but many questions for A Level biology and Chemistry require the use of Standard Deviation, which can be easily done on the calculator, rather than by hand. There are many different videos on YouTube giving walkthroughs on how to use the Stats mode on the calculator.

          This calculator is perfect for every day use as the buttons are very clear to use and it works really well for just simple calculations. For around £10 you're getting a really solid product which is going to last you a long time.

            Disadvantages

            Excellent calculator for anyone on a budget and needing basic science functions

            I have to have a scientific calculator for my course and have needed one since GCSE, so I bought this some years ago. It still works perfectly! Mine has a dual component to it - solar panel and battery so I can use it in any conditions and not have to replace the battery so often which is a major bonus as my previous calculator battery died just when I needed it most! It costs around £7.99 (in most stores and online) which isn't very expensive for a good quality basic scientific calculator especially from a trusted brand like Casio.

            The calculator itself is very light and compact so it fits easily into a bag/is easy to carry around day to day if you need it regularly. It also has a hard plastic casing including a lid so it's quite durable, I've never known anyone to break theirs. The screen has a hard protective plastic above it (very transparent it doesn't affect the view) which is better than some calculators that just leave the film which is prone to breaking - thankfully this calculator circumvents that.

            It's very simple to work, the number pad is at the bottom with the basic + - / x = functions. All of the others are in a smaller key pad in the middle of the calculator, some you need to press shift or alpha for (as there are too many functions to fit on one calculator) but this is easy to figure out and doesn't use much more effort than the other buttons. It does every function that you will really need on a basic scientific calculator.

            One annoying point about the calculator is that when I get an answer it gives it to me in a fraction. There must be a simple way of fixing this on the options menu but I can't find it, and neither could my tutor when I gave it to her. This means that you have to press another button to get the number and decimal view, which although isn't that taxing, it's still annoying.

            Overall, this is a well priced durable calculator suitable for the majority of scientific calculations. It may not be suitable for someone doing complex maths/physics but it definitely has enough functions to cover most subjects. I would definitely recommend for anyone looking for a reliable calculator but not significantly invested in it to spend a lot of money.

            Disadvantages

            a must have for those who cant do maths....or who love maths....or anyone!

            I first bought this calculator as i needed it for my maths exams. Since then, i haven't looked back and this calculator is all i use, even for simple things. After all, it helped me to pass my exam!
            Looking at the calculator, it is much more stylish than any other scientific calculator out there. The mix of colours of a blue on button, an orange clear button and black for the numbers means you can get your fingers working quickly because it is clear what does what. The buttons are also quite big so you dont end up pressing the wrong one. Even if you do, you can just delete that number instead of the whole equation.
            The big middle button at the top allows you to scroll up in your memory to see previous equations you've done.
            What i found extremely useful is the ability to change an answer into a fraction or decimal (by pressing
            S<->D button when your answer appears) and you can even work out percentages easily with a special % key (press "shift" and the left bracket key "(" to bring this up). Because of this handy tools, i can use this calculator for all of my maths needs as it does everything. Even if you are looking for a basic calculator, i would still recommend this for its ease of use and reliability.
            The best part about this calculator is that you can even have fun with it! you can make words on it too such as BEE, FEED by pressing the "alpha key" and then then button that has a red letter by it. If you want to have even more fun, just press "shift" and the "x-1" button.....you'll have to see what that makes for yourself!
            It is honestly a great calculator. Definately recommended for maths exams and even for general usage.

            Fantastic calculator from secondary school to university

            Had this calculator for about 7 years now, still works like a beast.


            Build>>>Throughout its existence i couldn't tell you how many times this has been dropped, hit and generally thrown about, absolutely no signs of any damage at all, and works perfectly. Great if your buying this for your child, especially if you don't want to fork out for another one ever again.

            Features>>>> Great set of features, that allow you to save scientific constants to set variables, whilst having a lot of pre-installed features for easy access. The set variables were great for physics as you constantly have to enter in these 10 digit numbers, but with this feature its at the push of a button.

            This calculator has all the features for maths up to and including GCSE, and physics up to and including A-Level. (Based on personal experience)

            The screen is very clear, and comes with a hard plastic protective case, essential in keeping it damage free.

            It also has an excellent delete key, perfest for making small changes, and a past calculations recall button, good if you have poor memory



            Great buy for the price.

            Every person needs a calculator, and this should have a place in everyones home!

            I did A-Level maths, and a must for the subject is a scientific calculator. I bought mine from John Lewis, and at the time in was £20. I was so impressed with what it can do! It has obviously got the basic calculator functions, but I sort of expected even that to be complicated to work, but its actually very simple.

            There are a multitude of other funtions avaliable ranging from the ability to use log, natural log, sine and cosine to being able to put into different modes (degree/radion/comprehensive/standard). What I found particuarly pleasing was the fact that the screen shows you all that you have inputted, which is useful for long calculations. However there is a limit to the amount of numbers that you can input at a time, and you have to pay attention to the screen, otherwise you could carry on pressing buttons and nothing will be inputted.
            They also come complete with a slide on cover, which keeps it protected in your bag, and stops you accidently turning it on.

            Not only that but I have had it for 3 years, and the battery is still going strong. I've finished my a-level now, but I still keep my calculator to hand by my computer, and use it reguarly. Even if you don't do a mathematical subject, for the price you can get it for I would recommend you buying it, simply because it works well and makes you feel professional :)

            Great for Alvl or GCSE maths

            I had to use this calculator all through my schooling and it is brilliant. It is a bit confusing to understand at first as you have to press certain buttons in order to get certain symbols, but once you have used it for a while it becomes second nature. The battery lasts for ages I had one that lasted 4 years and I used it most days during the week but some versions of this calculator come with a sola panel on the front so they last even longer. You can do pretty much anything on this calculator as there is a button for pie, recurring decimals, fractions, surds, sin cos tan, and much more. It's the calculator to use if you are taking GCSE or ALVL maths as it has all the formulas you need on it. It also has a function that changes the values for different number for certain types of calculations but i never had to use that function so don't know a huge amount about it.

            If you are doing long calculations sometimes i would recommend splitting it down into certain parts as sometimes it calculates it wrong or split it down just to check but it normally can handle long complicated calculations.

            Bright screen for easy viewing and does everything you need for a calculator.

            Top calculator

            As a 19 year old who has been through my GCSE's A levels and now at university in the past 5 years I know first hand that this is THE only calculator which is recommended by teachers and lecturers and also several industries.
            It is easy to use, light weight and has every function you would need in a calculator.
            The calculator is accompanied by a detailed instruction booklet and a cover lid with further simple instructions, which is extremely useful for homework at every level of education!
            Furthermore there is no need for batteries as it is solar powered and therefore it is a one off price.
            I have bought a different branded basic scientific calculator before and it was not anywhere near the level of the Casio one, especially on the ease of use and function level.
            I know that I will never buy another type of calculator again other than a Casio one as there is nothing on its level for academic use.

            A great all round product that really could only be better with a tin-opener extra

            Through all my years of education it appeared every time when it really was needed like those fun times called tests, the spurious calculators would cough, splutter and bow out with maximum inconvenience. Distraught and distrustful of all other brands and models I found myself searching far and wide for anything new with the some sort of reliability. This was the model I found.

            I was definitely impressed initially by the price, a mere £5 for what seemed like a very extensive set of functions. Not only did it impress at first but continued to provide a satisfactory product further more. It is hard to convey the excitement of having a calculator, something that will always be associated with those awful math classes that never seemed to end, but it really has been an essential piece of kit since I have continued my education on towards university.

            The display screen is easy to read, the wonderful tool of switching between natural displays is a great boon as well, the buttons are big enough for the fattest thumb and it can't be killed! It has survived a certain fall in the drink once and coming out working fine. I heartily recommend this sleek, small and suitable for every requirement calculator.

            Advantages

            Disadvantages

            Ideal for GCSE's

            I'll keep this brief, it's only a calculator after all.

            I've had a casio calculator of some kind since I done my SAT's about 10 years ago. Now might be a good time for me to admit my dirty secret, Im a calculator nerd.

            I get a bit pissed off with how often casio release new calculators, justifying themselves by the fact it now has a silver cover, or a new button which you're never going to use in 10000 years.

            This is the first time I feel that they've actually taken a look at the calculator and had a serious rethink. I mean realistically, there's not much they can do, I admit. Maths hasnt changed that significantly in the last 10 years.

            The first change is they've altered the body shape, it now feels a lot more ergonomic and useable, its alot lighter too which is a bonus. I do feel that they've used a cheaper plastic to achieve this making the product less... lasting. But it costs under a fiver these days, so I shant complain.

            Secondly, theres some improvements to help imrove speed when entering sums. The fraction key is now able to create a natural fraction by pressing 1 (fraction key) 2 for instance to enter a half, whereas previously one had to press (fraction) 1 (down) 2... the new way makes alot more sense.

            The third thing is some new functions, I've not used them, I've done too much maths to want to use them. But thining back to my GCSE days they would have been a god-send. It can give prime factors of a number and convert seconds into minutes and hours etc.... all very useful if you're lazy.

            Anyway. Im guessing not many school kids read dooyoo. But to any teachers / parents out there... this is a really decent calculator. They last a lifetime and do most things you'll come across. For those doing a-levels or their degree, theres a more expensive model that solves equations. This one is also permitted in exams!!!

            After a straightforward scientific calc with a touch of flair? This is it

            Casio have had the school scientific calculator market pretty much sewn up for as long as I can remember. Back when I was doing my GCSEs - shortly after we'd stopped carving notches on mammoth tusks - I had one of the original fx-82 models, and variants of that trusty machine served me well for the rest of school and beyond. The spiritual successor to that calculator is this one, officially dubbed the fx-83GT PLUS. Why Casio felt the need to use that idiotic ALL CAPS formatting is beyond me, but given that car-like "GT" moniker maybe it can be considered the equivalent of go-faster stripes.

            Styling is not something I care much about when it comes to calculators, and in fact I am perfectly content with the classic "rounded-off rectangle" shape. However, Casio decided to add some (relatively mild) swoops and curves to the GT. They're not offensive to the eye, but I don't think they add much either. The keys, which are made of the usual hard plastic and are fairly comfortable, are mostly fairly subtly coloured, except for the bright orange DEL and AC buttons. The overall impression is nothing special, but it'll do.

            If you are coming from a simpler and/or more traditional calculator, you may briefly be irritated by the fact that pressing the AC key doesn't turn the 83 on. For that, you have to use the dedicated "On" button up on the top row. I don't like this particular design choice: pressing AC to start makes perfect sense and works well, so why change it after all these years? It doesn't help that to switch off, you *do* need to press the AC button, albeit shifted. (Another change: on the old fx-82, the Shift function was called "Inv".) When you turn off, the display shows a large "CASIO®" splash, which though brief is intensely annoying.

            The big deal with this machine over a traditional calculator is the display. Banished is the traditional eight-segment LCD, and in its place comes a rather nice two-line display on which numbers - gasp! - actually look like numbers and - another gasp! - both sum and answer can be shown at the same time. This is certainly a very useful feature, especially as it is possible to use the four-way pad as a "replay" function to step through a sum, altering or deleting as you go along, which greatly speeds up repetitive calculations. More impressively, fractions, roots and powers are all shown more or less as they would be written.

            This being a school calculator, intended for GCSE and A-Level students, there are a few functions notable by their absence. For example, the GT will not do integration or differentiation, and it cannot solve simultaneous equations. The reason for these omissions is simple: calculators which can do them are not permitted in school exams, and so had Casio built them in they would immediately have lost their core market! Those are about the only obvious functions missing, however, and everything else you are likely to need in an everyday calculator is present and correct.

            Fraction handling, as I touched on a minute ago, has improved markedly in this model. I can still remember when calculators couldn't handle fractions at all; then for some years there was a rather clunky system of manipulating them. With the improved display on offer on the GT, fractions are shown naturally, as they would be written. If you multiply 1/3 by 2/5, you will see 2/15 shown as the result. You can convert this to decimal with the press of a button, but here is another new feature: recurring numbers are now shown in conventional notation, with dot(s) above the relevant digit(s).

            Another clever feature which I have not seen before on any of my calculators is automatic factorisation. This allows you to enter a number and have the GT break it up into its constituent factors - assuming it has any. For example, if you enter 12345678, press equals, and then press the [FACT] key, the result will come up (after a moment or two; this is tough work!) as 2x3^2x47x14593. (The power is actually shown as a proper superscript, but I can't do that in this review!) Of course, if you try this with a prime number such as 17, factorisation is of no use, so you'll just get back what you put in.

            One minor drawback of this calculator is that it is purely battery powered. It runs off a single AAA cell, which shouldn't be too hard to replace, though some fiddling around with screws will be necessary. The fx-83's sister model, the fx-85 GT PLUS (yep, same shouting in the product name!) is basically identical to this but boasts "dual power" with both battery and solar panel. You do pay a couple of pounds extra for that, so it's a toss-up whether to bother. There aren't many other real problems, though build quality doesn't seem quite what it was on the older fx-82 calculators: it's rather plasticky and the keys are very slightly loose.

            Because of the enormous volume in which these calculators are sold, you should be able to find the 83 pretty cheaply without having to search around too much. For example, at the time of writing Argos had them available for £8.99, but I've certainly seen them for less. WH Smith, not always the place I'd recommend looking for a bargain, can have some very good deals on school equipment, and at least once I've seen one of these in there for £4.99, which is outstanding value. The GT isn't a perfect calculator, but it's probably the closest you're going to get for that sort of money.

              Disadvantages

              Very good for a A Level standard

              I bought this calculator as my old one was a hand me down from my sister, who used it during her high school times, which must make this at least 7-10 years old. As technology has progressed since then, current calculators can do some fantastically advanced things mine cannot do, for example showing surds in the answer bar.

              The calculator has a sleek and round design, which is OK. I personally prefer crisp lines but almost all calculators today have this horrid shape... oh well... Judging more about the function, this calculator does everything I need and more.

              It has a large display which allows you to see everything you are typing into it, and the replay button allows you to edit your sums and calculations after you worked out the answer, which is a nice feature instead of having to punch in all the numbers again, extremely frustrating if you are working with long sums.

              The work that I've been using that needs to use this include Modulus, Exponentials, Logarithms, Statistics (combinations and permutations) and much more, all of which can be inputted into the calculator. It cannot directly do integration and differentiation. There are also some subtle features which are quite neat such as being able to turn minutes into hours, minutes and seconds, and turning radians into degrees and so on.

              One small thing I am going to have to criticise is once you have worked out your answer and want to input a new sum including your answer, the answer disappears on the bottom display, although is retained if you use the ANS button, which at times could be misleading. Also, it does not have mini solar panel which my old one does... so if it dies, I'll have to get new batteries, whereas my old one has lasted 10 years without replacing the batteries.

              The calculator cost me £7.99 from WHSmith and I managed to use a voucher I acclaimed somewhere so it was in essence "free" which I am very pleased about. I would highly recommend this calculator as it does everything you need and more- an essential item for students in high schools and universities.
