Casio FX 83 ES
Advantages: Easy to use, Price, displays fractions, many features, design, Memory store.
I have had this calculator for many years now, I remember I carrying this with me throughout my time studying GSCE, and A levels, I even took it with me to University just in case I needed it, however studying Psychology meant the calculator stayed in my bag most of the time.
This calculator is really cheaply priced compared to other scientific calculators;
Amazon has it for sale for around £7.00
Supplies Group: £9.42
It's worth noting the shipping costs, as some online stores have a hefty postage & packaging price. I am sure that it can be found at high street stores, it is worth shopping around.
==FUNCTIONS & USE==
This calculator is packed with features that any mathematician would find very useful, it is perfect for GCSCE maths, AS & A level maths and of course even university courses that require math calculations. The features such as fraction displays are extremely useful, for example the Casio display is perfectly sized so that it can display full fractions, making it incredibly easy to type in equations or algebra type fractions. I personally use to find it really frustrating before using this calculator and having to input each bracket to make equations etc; it was quite time consuming and can be a hindrance during exam conditions.
I know there are those out there that prefer to view fractions as a decimal answer, and thankfully this calculator can easily switch from fraction display mode into decimal view mode by tap of a button.
I personally like the idea of the use of the shift and alpha buttons located near the top of the calculator. This makes the calculator a lot easier to use and not too overwhelming or overloaded with unnecessary buttons, it impressively allows a few buttons to have more than just one function. This is a lot like having a shift key on a key computer keyboard and pressing that with the 1 key allows for the exclamation mark to be used.
The calculator is also useful when dealing with radians, degrees/gradians, statistics, and trigonometry; however I am not that clued up on these areas so I have not used these functions that much really explain the jargon correctly, however when calculating degrees and angles and some statistics I did find it very useful.
The use of the navigational buttons located on the top of the calculator makes correcting equations or simply tracking back through a long equation really simple and useful, there were many times when I had to go track back through a really long equation or input and found this function to be a life saver. The memory function is simply brilliant, it allows up to 7 calculations to be stored in the system, and with a press of button it can retrack back to the previous calculations used.
This calculator is really top notch; I have never had any issues with lag or delays when inputting data or when getting answers. I personally love the overall design of the calculator; the colour coded buttons themselves are large enough for both skinny and bigger fingers to skim through. The buttons are organised into similar function groups making them easy to find and easily accessible.
I found that the processer is highly efficient, as answers are swiftly given which is a must during exam conditions. The screen display is sized perfectly, allowing plenty of room for long inputted data to view clearly.
