Advantages: great features, easy to use and is cheap
Disadvantages: newer models available
This calculator has been with me now through thick and thin in everything that I have done so far. Purchased around 4-5 years ago, this reliable workhorse has helped me in GCSE, additional, AS and A2 maths. This version comes without the solar panel but actually that doesn't work that well and I find my calculator lasts just as long as a friends who has a solar panel (I have only replaced the battery twice).
The main reason that I like this calculator so much is because of it displaying fractions as actual fractions. This 'natural display' as Casio call it, has made inputting equations and reading off answers much simpler and reduced errors as you don't need loads of brackets to separate divisions. As for the rest of the calculator it has everything needed for someone to complete their further mathematics A level and actually the first few years of an engineering degree (I am only upgrading now as I am somewhat lazy and have found a calculator that will integrate for me).
This calculator can perform trigonometry, statistics and show in radians, degrees or gradians. Personally for statistics and some other maths exams I found it easier to also have a graphical calculator by my side for help with drawing graphs and inputting statistics into tables for finding variance or similar problems. However this calculator can perform statistics for you but just not as clearly and with a little more button pressing.
Another couple of handy features that I feel are worth a mention are the replay buttons that allow you to look through your calculation history so it saves you typing out the same calculation again and also allows for editing of calculations. The memory storage buttons are also the easiest to use that I have ever seen on a calculator. This product allows for 7 answers, numbers or calculatiosn to be stored at once and it is simple to recall or overwrite these.
---Ease of Use---
For exams or everyday use this calculator a great choice with a large clear screen and good processing power so that it hardly ever lags and you can input values quickly in a mad hurry to finish before time runs out. The buttons are fairly large so even big fingers can use them and they always fire when pressed so that you don't miss a value out accidentally and wonder why your answer is wrong. The layout of the buttons is also very efficient and after a while you realise how similar functions are grouped together nicely and you start to remember where buttons are without looking at the calculator, it's that intuitive.
Admittedly not the main basis of what makes a calculator good but yes this sadly does affect sales. This calculator has now been superseded by a newer and more stylish design but actually I find that it is still a very pleasant calculator to use and look at. The finish is blue grey plastic with colour coded buttons and functions so that it is clear where everything is.
This calculator is very good and comes with some easy to understand instructions (though you probably know the best way to learn a calculator is to use it repeatedly, personally i becamee familiar in just a few minutes due to its simplicity) and a sturdy lid to keep the product safe. Over time my calculator has developed a few scratches and pen marks but has not broken and continues to work perfectly like the day it was bought. A great buy for a decent and simple yet powerful calculator that is actually very cheap and does everything you need.
Summary: A great calculator that will last you out.
