Casio FX 85 MS
Advantages: Cheap, lasts forever, does basic functions very well
Disadvantages: Can't do advanced functions, not ergonomic, bad quality lid
I have had this calculator for as long as I can remember, and it has truly been a loyal companion on my mathematical voyage!
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.
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!
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!
Summary: Recommended as a reliable office calculator
