I was provided this calculator by my school so didn't purchase it myself but I know it is readily available in most shops (WHSmith - £9.99, Tesco, Argos).
The calculator is made by Casio which is a well known and trusted brand for calculators. The dimensions are 84x155x12mm and it is light to carry. It comes in two parts - the main calculator (black face and grey base) and plastic sliding lid (grey). The lid is easy to use although personally I just keep the lid on the back leaving the calculator displayed all the time. The keys are large enough for easy use and also all writing is clear on and above the keys.
This is a scientific calculator with 249 functions (164 scientific functions) - including statistic functions. It is ideal for and aimed at secondary school students (11-16) but can also be used post 16. (I got through my A-levels and degree with an ordinary scientific calculator - never needed a graphical one).
One of the key features of this calculator is the 'Revolutionary Natural Textbook Display'. This allows you to enter expressions as seen in a text book and displaying answers in the same way. For example, fractions are written as one number over another. In a regular scientific calculator you can only display this using the ‘a b/c’ button and end up with a symbol like this ┘. But with the natural display you can type a fraction as a fraction should be written and the answers are given in the same manner. This works for surds as well, but for other functions you can type it in text book manner but will get your answer as a number (for example in indices 7^4 x 7^3 gives the actual value and not 7^7).
I think this feature is very useful but I find it fiddly to use as you have to use the scroll button to get the number in the right place. It’s easy to get use to, especially if this will be your first scientific calculator.
It is solar powered so will hardly ever require battery replacement (I have never changed the battery in my own Casio solar calculator which is over 5 years old now!). The calculator came with fold out user guides in several languages. I think a booklet would have been more useful; nevertheless, it is easy to follow and covers all the functions of the calculator and everything you will need to know about it, e.g. getting started, precautions, and technical information. Lots of diagrams and examples are included making everything clear.
Overall, I would describe the as a modern calculator and the natural display is probably something that most new calculators will feature. Personally I wouldn’t buy it as I am very happy with my older model.
It is definitely a good buy though! Casio is a well known calculator maker so you can be assured that you are getting a good product. Being solar powered saves on batteries and a good scientific calculator can be used throughout all education years (secondary onwards, not needed for primary).
Advantages: Reliable, Long battery life and very handy! Disadvantages: Long mathmatical equation inputting not so good.
This Casio calculator has been at my side for approximately at least 5years now, and is in more demand now than previous use. I have used this calculator in 3 main areas. 1. General GCSE
2. Chemistry and Biology A-level and now
3. Chemistry degree (first year only so far…)
GCSE:
Harking back to the good ole days (why are they called the good ole days? Someone please tell me why!) My calculator joined me in my quest of maths at the tender ... ...asked to do was to deal with are such aspects as addition, subtraction, multiplication, division, square roots, powers and bracketed equations. These are the basics of most maths until a level maths, and on these small calculations it doesn’t fail. One would think that if it did it wouldn’t really be a good calculator! (By the way don’t forget good old trigonometry and standard deviation!)
A-level:
More complicated calculations that are ...

Advantages: Very cheap and solar powered Disadvantages: No
Casio is the leader brand in calculators worldwide up to now it's the only brand I ever use. Bought this one from Argos two years ago only to have it as a spare in case the other dies of batteries in the middle of the exam since it was cheap and it was solar powered so no need to have to worry about batteries.
When I first switched it on I freaked out when I saw the natural typing they added in this new series of models and was very relaxed when ... ...to use.

Advantages: Natural textbook display, Easy to use, Good value for money, Casio, everything!! Disadvantages: None!
...I never once regretted it. Casio have always been my favourite brand of calculators, but this is definately their best yet. I have found it extremely useful in both core maths and statistics.
The ability to view your calculations as you would see them on paper helps to see what you are doing and make sure you get the operations in the right order (no more BODMAS mistakes with this calculator!) It's a very easy calculator to get the hang of, and ... ...do you see sums as you type them in, you can also view data in tables, or even find out which numbers would occur in a series without having to work it out. The log to any base function is also very useful as an A level student. I would recommend this calculator to anyone, whether they do complicates maths sums or simple ones. If you're going to buy a calculator, buy this one - It's not expensive, around £10 in most shops, and, although there are ...

Advantages: Great for A levels and beyond! Disadvantages: can be a bit fiddly to begin with
...one cos i trusted the Casio brand and also i liked the colour :P...
the first thing you will notice is that the display is completely different to other calculators. it has a natural display, meaning that what you type in to it will come up on the screen as you would see it in a textbook or on paper. at first it took a while to get used to and figure out where the buttons where. but after i was used to it it made my life soooooo much easier!
And ... ...new electronic stuff, the included manual teaches you all you need for this.
AS levels are hard enough! but this calculator actually makes them much easier. having a display that looks like the textbook makes working out and reading off calculations much easier! it also saves time as multiple things can be done at the same time that would not normally have been possible with the old '2 line display' calculators. Overall if you are doing A levels ...
