I have had this calculator for as long as I can remember, and it has truly been a loyal companion on my mathematical voyage!
~~~EXTERIOR~~~
The actual body of the calculator is made out of navy blue/black soft plastic, it measures 7.5cm in width and 13cm in length, so it is quite a big calculator but it isn't as chunky as some of the old models of calculators.
Although it isn't exactly chic, it is very functional and the buttons are colour coded such as black for functions, light grey for modes and dark grey for numbers etc. This is great for inputting functions quickly
The buttons are slightly hard to press and aren't exactly ergonomic, but it is only a calculator I guess! One disadvantage is that the lid doesn't have a snug fit and it can easily can lost, which is infuriating at times.
The actual display is quite small but it is very clear as it is has a horizontal flashing line as opposed to vertical which is very mathematical and it allows you to clearly see which mode you are in at the top.
~~~MATHEMATICAL FUNCTIONS~~~
This calculator is fine for daily use e.g. totting up bills, but in terms of academic maths, I only recommend it for GCSE Maths and not for A-level.
This is because although it has all the modes which are relevant like radians, but it doesn't leave answers in surd form which is important in topics such as trigonometry and this can be frustrating. In addition to this, it doesn't leave anything in terms of an irrational number like pi, which isn't idle when answering questions specifying this.
This calculator has all the statistical functions like permutations/combinations however, it doesn't have advanced functions such as integration/differentiation which is imperative in A level.
In fairness, it does have all the basic functions such as logarithms and basic powers. It is sometimes annoying as when you are entering indices specifically for raising numbers to powers greater than three you have to use an index symbol which is time-consuming. To the contrary it performs demanding calculations quicker than other calculators and leaves them in standard form which is great!
~~~OTHER INFORMATION~~~
This calculator is very reliable due to its two way power system since it has an integrated solar panel and it lasts for years! And I mean years! However, the calculator doesn't turn automatically off when idle for a long time, which means that the battery can easily deplete.
It is quite heavy to other calculators and can seem rather dated at time in both aesthetics and function. It doesn't list all modes on the screen due to the small display and hence you keep have to press the mode button which can take a lot of time.
This calculator is quite reasonably priced at only around £15.00 a few years ago at WHSmiths (I'm sure its value has depreciated!)
It is definitely recommended as a staple item in the office!
I have, in my not very long life, been the proud owner of six different Casio calculators, four of which are the FX 85MS model. The FX 85MS scientific calculator, being approved for general classroom usage, public examinations and university assessments, helped form the absolute foundation of my serious school then university education, and has been my most trusted companion for all the academic tasks I had to perform.
It has a two way power supply of solar cells and an auxiliary battery, a TwinLine display (the top being the raw data input, and the bottom is the intermediate or final answer calculated) where 12 and 10 digits can fit comfortably on the top and bottom lines of the LCD screen. It comes with a hard plastic case with a total dimension of (H x W x D) 12.2 x 85 x 155 mm, weighing at 110g.
I find the buttons to be well separated and response well when pressed, there is no sign of numberings, or any printed ink letters, to have come out, even after years of quite rough handling. The calculator has been dropped onto the floor countless times and it is still going strong. I wouldn't know how long the battery lasts but I would assume when it does the calculator would be powered solely by its solar cells. The reply button has saved my life many times, because as long as you use the 'AC' red button to switch to a new calculation and not the 'ON' grey button, you can press Up side of the 'Replay' to find your previous calculations. I have used the calculator for all my science exams, further maths and statistics, and it has given me the most stable performance.
Online retail price range from 10-25 pounds but schools often sell them for much cheaper. If you fancy yourself a shiny new device for everyday calculations, statistical analysis, or just as a nostalgic item, the FX 85MS would not disappoint.
*Full list of functions can be found on the manufacturer's website.
I have been using this calculator for as long as I can remember, years in fact. It has never let me down, never malfunctioned, survived being painted with tipex at school and not a sticky button in sight! Even the battery (coupled with the solar panel) lasted right up untiol only a couple of months ago, so the lifespan of this product is just remarkable.
This is one of the perks I find of having both means of power: that in light you conditions you dont even have need of the battery, so you can have faith that the calculator will survive for a long time, which it has in my case.
The buttons are very simply laid out and even complex equations are easy to construct, knowing that you can scroll back and review them easily.
So all in all it has served me well for a number of years, staying in charge and not dumbfounding me in terms of its functionality. I would recommend this to any scientist, whatever their level of needs or understanding.
I bought this calculator in year seven to start secondary school and it managed to do everything I needed it to do right through all seven years at school including doing maths and further maths at A-level and its still going string studying maths at university.
It has lasted remarkably well for its age and all the more for the fact that it was left in the side pocket of a bag and dropped and kicked around all the time. It comes with a protective cover that slides of the front and can be put on the back to keep it safe while using it. It has done a brilliant job and the front is hardly even scratched. The back and the case are not looking new but by no means are they in bad condition.
The operation of the calculator is very intuitive and easy to use. The display has two lines allowing you to see the whole equation that you are typing in. The top line (for the equation) is 12 characters long and the main line (answer) is 10 digits and has the ability to write in standard form for larger numbers (rather than giving an error as some do).
It has an 'anti rounding error' feature in it that stops it truncating answers (eg (1/3)x3 = 1 not 0.99999999999 etc). It has the facility to save 9 numbers at any one time and to do calculations with these numbers by typing in the letter associated with the up and down arrows or scroll through and edit the current calculation with the left and right arrows.
Another useful feature is that you can scroll through previous answers using the y
If anyone is looking for a calculator for school or college work, this is the one I would recommend every time.
I have had this calculator since I started my GCSEs - that's over four years ago. I have used it right through my GCSEs and A levels and it still works in the condition it did from day one, which is quite astonishing. It's a very reliable gadget and popular amongst students even to this date. It is great for all subjects ranging from mathematics to physics and business studies. It has many functions, which enable you to perform a variety of different things.
The calculator is dark grey and comes with a lid, which simply slides over the buttons to protect it. When using the calculator, you can slide the lid onto the bottom, so your calculator comfortably sits on the lid. This way, you won't lose it. A standard number pad in grey buttons with white writing is on the bottom half of the calculator including all signs such as multiplication, division and plus or minis signs. There is also a decimal point for use with decimals.
On the top half of the calculator are black buttons with white writing, which look very strange, complex and confusing at first. However, their functions will become clear to you as you advance through courses - especially mathematics. If you do mathematics to Advanced Level, you may encounter topics that will require some of these buttons such as logarithms and exponentials and of course - everyone's favourite: trigonometry. Above the black buttons is a set of light grey buttons, which includes shift and alpha. These are like the shift button on your keyboard, and enable you to access more functions, as keys will have more than one action. There is a directional pad in the middle, used to scroll through digits on the digital screen so you can place the curser and delete or add where you want. There are also 'mode' and and 'on' button. The mode button gives access to all different things, which may be used in statistics for example. The calculator is a lot more capable than it even looks; it has many features and you will need such a calculator if you do choose to do Advanced Level mathematics and even other subjects like physics and chemistry.
The top of the calculator has a solar panel, which is great as it uses natural light to prolong the battery. With all classrooms having adequate light, this enables you to run the calculator on the same battery for.. years! After almost 5 years, my calculator still has a decent display and isn't faded. The addition of the solar panel is brilliant as the calculator doesn't need much energy to work anyway, so can almost solely be powered by the solar panel.
The calculator is very well made and resistant to drops such as when you're walking into the exam room with shaking hands. Not only is it ideal for students, but may be useful for certain job areas where mathematics come into play. With 7 screws in the back, it won't fall apart easily. The lid is great as it protects it too, but note that you're not allowed to take these into exams nowadays as they contain some formulas on the inside. The lid has a Casio logo on the outside and is dark grey to match the base of the calculator.
Overall, this is a superb gadget and pretty much necessary if you're studying maths. It can be bought for around £10.00 in shops that haven't renewed their stock, as there are newer versions out there now. Considering some more advanced calculators are banned from exams due to their functions, you would be better off taking this calculator into an exam as it's allowed and already has a whole host of functions.

This calculator has taken me through all my years in school of maths in the sciences and pure maths. Having taken maths for A level, this calculator was necessary for me during the exams as it is a fully scientific one with all the functions needed.
It is grey and comes with a case to protect it (these are never allowed in exams though). The case has the Casio logo on it and simply slides over the calculator. The calculator itself has grey buttons consisting of the normal numerical side of things with all the mathematical signs too such as 'x', '+' and '-'. There are two red buttons above these including a delete key, which is very useful when you make a mistake. This way you can delete a certain figure by scrolling back along what you have typed in using the directional pad at the top. Beside this D-Pad are the 'on', 'mode' and shift/alpha buttons. The shift/alpha buttons are like the shift button on a computer and simply give secondary functions to keys when pressed. There are many different modes that you can go to such as statistics for use in this subject area.
This calculator is very capable and has always been used in exams. It's very easy to use once you get used to it and will take you through Advanced Level maths without a problem! I would highly recommend it, as it costs a few pounds. It may be harder to buy as most shops are now getting the newer Casio versions in with a larger screen able to fit more on so you can enter more complex sums.

This Calculator, Casio FX 85 MS, is a great calculator for hanging round the house, or for those of you awho are getting ready to go off for your A-Levels, GCSE's or SAT's, it's primary function keys are exactly what is required for the aforementioned exams and i can asuure you, it's a well known and trusted brand of calculator! You can also put your mind at ease if you're thinking "My child has to get a scientific calculator, which one though?" This one!!! It got me through my SAT's GCSE's and is currently getting me through my A-Levels so it has everything that any paper will want you to have! It also has total recall up until the last shutoff point, and well marked buttons so there is no confusion between buttons and what to press! Casio, Overall it's a great calculator for those on their way to success!
A very nice calculator that is very popular with people everywhere. You can't go wrong with puchasing this calculator, because of it's classic appearance and very scientific functions and buttons.
Its very good and easy to use for any person, well, except a young child of course. This Casio has accompanied me on many of my GCSE exams and has proven very useful and reliable. It has not broken down on me and looks very nice.
It comes with a very good cover that slides on and off to protect the calculator and keep it in tip top condition.
It has many buttons that will help to carry out numerous calculations in both maths and science topics. There are different modes to use, but I have not understood what they do yet!
So, overall, a great piece of equipment that is very good and allows you to get a lot of use out of it.
This is, or at least should be, the standard calculator in schools and offices up and down the country. Its greatest plus point is its ease of use, so many calculators try to cram hundreds of functions and writting onto a small space. This however is simple to use, the buttons and words are spaced out and is small enough to fit into a pocket. Yet it is still able to carry out complicated operations, it includes inverse trigonometric, logarithmic and exponential functions, all on a sleek looking, pencil thin piece of kit. The solar panel on this model is a possible as (although using a calculator is not particularly energy consuming) the battery will run down, and although inexpensive to replace, it is very irritating if you go to use a calculator and you find out the battery is dead. In my opinion, although this might sound odd, Casio calculators are an outstanding piece of engineering
I have still got my calculator from school having done maths and sciences at A level. It is a scientific calculator that proves to be very useful in subjects such as statistics and pure maths. It is very easy to use once you get used to it because everything makes sense.
The bottom of the calculator features all the numbers needed and symbols for working out sums. The important keys are highlighted in red, which are AC/OFF and Delete. The delete key is a real bonus and very useful if you make a mistake in a long sum so you do not have to start over.
The calculator is great for long sums, with the use of brackets too. If you know how brackets work, then you can type in a large variety of sums on here and get the answer quickly. There are many different modes that prove useful in statistics and other subjects, enabling you to work out anything from standard deviation and variance to product moment coefficients and more. There are two keys that enable you to type more from the keys shown. The shift and alpha keys at the top set you in mode, so that when you press a button with a secondary function highlighted in the corresponding colour, it will put that on the screen. Its similar to a shift key on a keyboard really, in the way that some keys have secondary functions such as the explanation mark, question mark and @ logo.
Overall, it is really easy to use and can do anything a modern calculator should do. It is not the newest version but it is currently the standard version that the majority own. It is reliable so shouldn't break during exams! It also has a two way power so it can gain energy from natural light as well as the battery. The battery itself lasts ages anyway and should easily work through your A levels/GCSEs or even both! It also switches off after around 2 minutes if you have not touched any keys anyway, to save power, which is a great selling point. It comes with a lid to protect it and all of this is for around £6.99 in shops such as WHSmith and Partners.

This calculator has been with me through the hardest times. When I was studying maths and sciences, I needed this calculator, especially for maths and statistics to get me through the exams. It went through some mind-blowing exams with me and we both survived the journey! I love my calculator, and it works brilliantly. I customized it when I got bored by putting Tip-ex on it in a certain pattern, and then later colouring it in with highlighter pens. I also stuck some stickers on the back to lighten it up.
Anyway, this is a proper scientific calculator that is ideal for current examinations up to degree level. It has 240 functions with 164 scientific functions and 9 variable memories. It also has two way power, because it comes with a battery but also has a solar panel that does actually give it some extra energy. The battery has lasted me years of good usage, and is still going so you don't need to worry about it running out during an exam, although you can never be to cautious!
The curser allows you to move along the screen to see what you have written if you think you went wrong whilst inputting data. Also, the delete button I have found extremely useful when I always input something wrong by accident whilst in a hurry. I couldn't live without that button! It can work out all the statistical things such as standard deviation, regression and all those fun things with graphs.
You simply input the data using commas or semi-colons depending on what you are doing (make sure you are in STATS mode too), and you then press some more to get the answer right in front of you. So much easier than doing the insane looking formula by hand to work out regression and correlation coefficients with graphs! NOTE: In exams, and they did this in one of my statistics exams, you had to use the long way by hand to work out something, so always learn the long hand way!
The calculator has an automatic power-off function so it will switch off when its not been touched for a few minutes, which is very useful and saves battery. It looks really cool and has loads of buttons, that you will have to learn what they do if you go into higher mathematic courses. It is very useful and can work out all modern day calculations.
It isn't the newest Casio, but does everything you need it to and I think it still has to be from the most popular range and generation of the Casio calculators. It is grey, with the solar panel at the top right and the logo and model code on the left of this. Below is the curser in the middle with the on button to the right. All the important buttons are at the top such as 'on', 'mode', 'shift', 'alpha'. The shift and alpha keys are used like a shift key on the keyboard, just to access more symbols and digits you may need to input. Below these top buttons are a range of black buttons that provide you with all the symbols and most of the inputs. Then below this, you have all the numbers and symbols for adding, subtracting, dividing and multiplying as well as the equals sign and more.
The delete key is in red to make you aware, which is good and the AC key is too, which will reset what's on the screen (delete it). It is important and a good point that these keys are in red, because the last thing you want to do is accidentally press the AC button after just inputting a big sum with lots of brackets! Therefore, because these buttons stand out, it prevents this!
The calculator also comes with a hard plastic sliding cover that protects it well. They are pretty tough things anyway and well built. No buttons have fallen off or got damaged, the cover works brilliantly and protects it and the screen isn't scratched too much and still displays every part of the screen well. It is easy to use if you know what you are doing, and the instruction manual is simple and helpful that comes with it in many languages, if you know what you are looking for.
At £9.30 on amazon.co.uk and around £9.00 in shops offline, I would say this is a great scientific calculator to buy. I have had no problems with it, and it is relatively easy to use, although it looks complicated. It can perform every function you need for modern day exams and is well built with a strong cover to protect it from any other damage. I would recommend this calculator to anyone taking mathematics exams...and good luck too!
